§511. General Requirements

[formerly paragraph 13:011-1]

A. Connections to Community Sewerage Systems.

Where an established community sewerage system

(either public or private) is available, and there is ample

water supply, all plumbing fixtures within any structure

shall be connected to such community sewerage system.

Determination by the state health officer of the

availability of a community sewerage system shall take

into consideration, among other aspects, the separation

(both horizontal and vertical) of the structure in question

and the sewer main or lateral, political or geographic or

legally created boundaries, and the available capacity of

the sewer system.

B. [Formerly paragraph 13:011-2] Community

Sewerage System Required. Community sewerage

systems shall be provided for all new subdivisions and

developments where lots are sold or leased. The

developer/owner shall be responsible for the provision

of adequate sewage treatment and disposal. The use of

individual sewerage systems in lieu of a community

sewerage system may be authorized and will be

considered under the following circumstances.

1. In subdivisions comprised of less than 125

lots, when the developer submits a comprehensive

drainage plan as well as a proposal for restrictive

covenants which detail requirements for perpetual

maintenance of drainage. This requirement shall

apply for all new subdivisions and developments.

2. When the total anticipated design flow to

the sewerage system does not exceed 1,500 gpd,

and where no food service is involved as per

§1301.A.2.

3. On large lots, where an area of one acre or

more is involved, having a minimum frontage of 125

feet.

4. The installation would be located on a lot,

plot or site which has a minimum area of 22,500

square feet, and a minimum frontage of 125 feet.

5. For subdivisions when each and all lots have

a minimum area of at least 22,500 square feet and a

minimum frontage of 125 feet, except that the 125

foot frontage requirement may be waived for up to

15 percent of the total number of lots in the

development if:

a. minimum frontage on each lot in question

is not less than 60 feet, and;

b. the width of each lot in question is at

least 125 feet.

6. For parishes in which the parish governing

authority has enacted and enforces a formal sewage

permitting system (requiring approval of individual

sewage disposal systems by the state health officer

prior to issuance of any parish permits) and when

the lots or sites in question meet any of the

following criteria:

a. minimum area of 22,500 square feet and

a minimum frontage of 80 feet;

b. minimum area of 16,000 square feet and

a minimum frontage of 80 feet where an approved

individual mechanical plant is to be utilized;

c. minimum area of 12,000 square feet and

a minimum frontage of 60 feet where an approved

individual mechanical plant is utilized and is

followed by 50 feet of modified absorption field

(see Chapter 7 Subchapter B, §733.A).

7. Where lots of "record" (i.e., lots created by

formal subdivision prior to July 28, 1967) are combined

(in accord with the definition of a subdivision) to create a

new, larger, single lot, and no re-subdivision of the

property is involved. On July 20, 2002 and thereafter, in

no case shall the newly created lots have less than 50

feet of frontage or be less than 5,000 square feet in area.

8. For single lots or sites, regardless of size,

remaining in substantially developed previously

established subdivisions, when, in the opinion of the

state health officer, a hazard to the public health will not

result.

9. For single lots or sites, regardless of size, when

the installation of an individual sewerage system is

proposed in order to renovate or replace a pre-existing

sewerage system. Such installation may be allowed

when, in the opinion of the state health officer, a public

health hazard or nuisance will not result. This provision

shall apply to the renovation or replacement of pre-

existing systems only and shall not be utilized to

circumvent other requirements, particularly those

relative to minimum lot size for new residences and

subdivision development, of this code.

C. [Formerly paragraph 13:011-3] Effective October

20, 2000, this rule applies to new individual sewerage

system installations, upgrades and/or modifications to

existing systems required as a result of an investigation

by the Office of Public Health (OPH) into an allegation

that a violation of Part XIII of the Louisiana sanitary code

has occurred or is occurring, and has the potential for

causing harm or creating a nuisance to the general public

(R.S. 40:1154). Such individual sewerage systems with a

capacity up to and including 1,500 gpd, that produce

treated effluent, and which, by design, do not

significantly reduce the amount of off-site effluent, shall

be followed by an effluent reduction system constructed

as described in Chapter 7 Subchapter B, §§731 and 733

of this Part.

D. [Formerly paragraph 13:011-4] The state health

officer may consider for approval, on an individual basis,

proposals for developments that are of a unique nature,

such as a development over water, or irregular

configuration, where individual sewage disposal is

proposed, where the development, by its very nature

(e.g., where commonly or jointly owned property is

involved), is clearly not addressed by the current

considerations of this Code.

[formerly Chapter 13 Subpart D]

Subchapter A. General Requirements

§701. Permits

[formerly paragraph 13:012-1]

A. A person shall not install, cause to be

installed, alter subsequent to installation, or operate

an individual sewerage system of any kind without

first having obtained a permit from the state health

officer. No person shall install, cause to be installed,

or alter subsequent to installation an individual

sewerage system of any kind except in accordance

with the plans and specifications for the installation

which have been approved as a part of a permit

issued by the state health officer. Such permits shall

be issued in a two-stage process in accordance with

§701.B and C.

B. [Formerly paragraph 13:012-2] Upon receipt

of a request for such permit, and approval of plans

and specifications for the proposed individual

sewerage system (which shall accompany any such

request for permit), a temporary permit, authorizing

the installation of said system, may be issued. Any

such temporary permit shall be in writing and shall

not be issued until, with respect to the property and

its surroundings, the state health officer has

determined that connection to a community-type

sewerage system is not feasible, and that the

condition of the soil, drainage patterns, the lot

size/dimensions, and other related factors are such

that the construction and use of properly designed

individual sewerage facilities are not likely to create

a nuisance or public health hazard.

C. [Formerly paragraph 13:012-3] A final permit

approving the installation, shall be issued only upon

verification that the individual sewerage system has

been installed in compliance with this code. The

verification of such installation shall be determined

by means of an on-site inspection conducted by a

representative of the state health officer and/or in

the form of a completed "Certification by Installer"

form submitted to the state health officer by the

licensed installer. The installer shall notify the

appropriate local Parish Health Unit prior to the

installation of an individual sewerage system. The

sanitarian shall not issue final approval for this system

unless he/she has received a completed and signed

certification by installer form. The certification by

installer shall be submitted to the state health officer

within 15 days after completion of the installation. A

final permit shall be issued and provided to the

owner/occupant of the premises to be served by the

individual sewerage system.

D. [Formerly paragraph 13:012-4] If a consumer

currently owns, is contemplating purchasing and having

installed, or is an installer of Individual Mechanical

Sewage Treatment Plants, that consumer should be

made aware that:

1. it has become apparent that the electrical

components of Individual Mechanical Sewage Treatment

Plants which require connection to a source of electricity

may not be properly connected to that electrical source

in some cases. Specifically, mechanical sewage treatment

plants, using electrical power may require a properly

installed Ground Fault Current Interrupter (GFCI);

2. the Office of Public Health has specific statutory

authority and mandates to protect the public health

from the improper treatment and disposal of sewage.

This office will offer the public consultation with regard

to the appropriate sewage treatment system that should

be used in a specific application, considering system

design for properly treating sewage, sizing for the

number of people using the system, location of the

system, and other health considerations, as necessary.

However, the Office of Public Health does not have the

authority to inspect or approve electrical connections,

are not qualified in the area of such electrical

connections and will not assume responsibility for such

electrical safety considerations;

3. accordingly, proper electrical connections must

be made to the air pump/blower and/or any other

electrical components that are integral parts of an

individual mechanical sewage treatment plant, and that

a qualified electrician should perform or examine the

installation(s) for appropriate wiring and installation, as

well as the connection to the ground fault current

interrupter.

E. [Formerly paragraph 13:012-5] Permits for the

installation of individual sewerage systems shall not be

issued for lots within a formal subdivision unless an

official recorded plat/property survey has been filed with

Subchapter B. Design and Construction

Regulations

[formerly Chapter 13 Appendix A]

§715. Septic Tanks

[formerly Section I of Appendix A]

A. [Formerly paragraph A:1.1 of Appendix A] A septic

tank is a watertight tank made of steel, concrete or other

approved materials in which the settleable solids of

sewage settle out and are largely changed into liquids or

gases by bacterial decomposition. The remaining residue

in the tank is a heavy, black semi-liquid sludge which

must be removed from the tank periodically. Although

the completely digested sludge contains relatively few

disease germs, in cleaning the tank it is impossible to

remove the digested sludge without removing some

undigested material. Therefore, it is particularly

important that the removed sludge be disposed of in a

safe manner. There are commercial service companies

that will contract for septic tank cleaning and sludge

disposal. Such commercial services are controlled by a

permit system in accordance with §901 of this Part.

B. [Formerly paragraph A:1.2 of Appendix A] Multiple

compartment septic tanks or single chamber septic tanks

in series provide more effective treatment than single

chamber tanks of the same total capacity; therefore, the

use of multiple compartment tanks or single tanks in

series is encouraged. However, single chamber septic

tanks are acceptable.

C. [Formerly paragraph A:1.3 of Appendix A] The

velocity of flow through the tanks must be such that

maximum solids and scum retention is achieved. Vertical

cylindrical tanks must have horizontal (inlet-to-outlet)

separation of at least 24 inches.

1. Tees or baffles must be used at the inlet. The

outlet must be designed so as to preclude floating solids

from escaping from the tank. The inlet tee or baffle

diverts the incoming sewage toward the bottom of the

tank without disturbing the scum which forms on the

surface of the liquid, and the outlet prevents the surface

scum from flowing out of the tank.

D. [Formerly paragraph A:1.4 of Appendix A] The

minimum total septic tank liquid capacity required is 2

1/2 times the estimated average daily design flow.

Sewage loading criteria for determining the average daily

design flow and organic loading are contained in Chapter

15 of this Part. One-bedroom residences may, however,

utilize a 500 gallon tank.

NOTE: The minimum allowable total septic tank volume

for all applications is 500 gallons.

E. [Formerly paragraph A:1.5 of Appendix A] The

distance between the inlet and outlet openings in

the tank wall, measured horizontally, shall be not

less than 24 inches. The distance between the inlet

and outlet shall exceed the width of rectangular and

oval-shaped tanks.

F. [Formerly paragraph A:1.6 of Appendix A] The

tank shall operate with a liquid depth between a

minimum of

30 inches and a maximum of 72 inches measured

vertically from the invert of the outlet (overflow

level) to the bottom of the tank. Recent septic tank

studies have indicated the shallower tank to be

more efficient and is therefore preferred.

G. [Formerly paragraph A:1.7 of Appendix A] For

tanks having straight vertical sides, the dimension

between the top of the tank and the liquid level

shall not be less than 15 percent of the liquid depth.

In horizontal cylindrical tanks, the volume of the air

space above the liquid shall not be less than 15

percent of the liquid capacity. In the latter case, this

condition is met if the liquid depth (distance from

outlet invert to bottom of tank) is at least 79

percent of the diameter of the tank.

H. [Formerly paragraph A:1.8 of Appendix A] A

single tank may be divided into two or more

compartments by means of internal partitions. Each

compartment shall conform to the dimensions

limitations for complete tanks and shall have a

liquid capacity of at least 250 gallons. The total

liquid capacity shall conform to the requirements

for single chamber tanks. No tanks shall have more

than three compartments.

I. [Formerly paragraph A:1.9 of Appendix A] The

tank shall be constructed of materials which are

corrosion resistant and provide a watertight

permanent structure. The cover of the tank shall be

designed for a dead load of not less than

150 pounds per square foot. Concrete covers must

be reinforced with steel and must be not less than

4 inches thick. Metal septic tanks shall comply with

the requirements of §715.O. Tanks of other

materials such as fiberglass will be reviewed for

acceptance on an individual basis. They will be

required to comply generally with the basic

applicable standards for metal septic tanks.

J. [Formerly paragraph A:1.10 of Appendix A] Access

to the septic tank for cleaning and inspection shall be

provided by a removable cover or manhole. Both inlet

and outlet devices as well as each compartment in

multiple compartment tanks must be accessible.

Manholes, when used shall be at least 20 inches square

or 24 inches in diameter and provided with covers which

can be sealed watertight. Septic tanks with removable

covers must be provided with an 8-inch inspection hole

over the inlet and the outlet.

K. [Formerly paragraph A:1.11 of Appendix A] Either

tees or baffles shall be provided at the inlet of the tank

and shall extend upward at least 6 inches above the

liquid level of the tank. The inlet tee or baffle shall

extend downward to at least 6 inches below the liquid

level, but it shall not extend below the level of the lower

end of the outlet tee or baffle. At least 2 inches of open

space shall be provided above the baffle or tee to

provide ventilation to the tank through the building

plumbing system.

L. [Formerly paragraph A:1.12 of Appendix A] On the

outlet side the tee or baffle shall extend downward to a

distance below the water surface equal to 40 percent of

the liquid depth of tanks with vertical sides and 35

percent of liquid depth of tanks of other shapes as

measured to the nearest inch. If a tee or baffle is used in

the outlet the upper end shall extend 6 inches above the

liquid level.

M. [Formerly paragraph A:1.13 of Appendix A] Inlet

and outlet fittings (tees or ells) must be of cast iron,

schedule 40 PVC or ABS plastic or other approved

material.

N. [Formerly paragraph A:1.14 of Appendix A] The

invert of the inlet shall be located at least 2 inches above

the invert of the outlet.

O. [Formerly paragraph A:1.15 of Appendix A] Metal

septic tanks shall be prefabricated of a minimum of 14

gauge commercial grade steel. Corrosion protection

shall, at a minimum, consist of a hot-dipped asphalt

coating of at least 0.025-inch thickness properly applied

to all surfaces of the new, clean, bare metal.

P. [Formerly paragraph A:1.16 of Appendix A] The

location of a septic tank shall comply with minimum

distance requirements from water wells, water lines, etc.

as contained in Part XII, of this Code.

Q. [Formerly paragraph A:1.17 of Appendix A] The use

of septic tanks in series is encouraged. The first tank shall

have at least a 500-gallon liquid capacity and all

subsequent tanks shall have at least 300-gallon

liquid capacities. The total capacity of all tanks in

series must comply with the capacities for septic

tanks as prescribed in §715.D.

R. [Formerly paragraph A:1.18 of Appendix A]

Piping from the house to the septic tank must be

such that the waste flow does not disturb the

retention of scum and sludge in the tank. To attain

this, the inlet piping from the house must have a

minimum diameter of four inches and be laid on a

slope of at least 1/8 inch per foot. The slope for the

last 10 feet of line preceding the septic tank must

not exceed 1/4 inch per foot. All plastic piping,

excluding perforated pipe, must be a minimum of

SDR 35 sewer and drainage pipe or equivalent.

S. [Formerly paragraph A:1.19 of Appendix A]

Backfill around septic tanks must be made in thin

layers thoroughly tamped in a manner that will not

produce undue strain on the tank. Sufficient soil

cover can be provided over the top of the septic

tank to permit grass growth. However, no other

obstruction to access (i.e., concrete slabs, buildings,

etc.) shall be allowed.

T. [Formerly paragraph A:1.20 of Appendix A]

Septic tanks should be inspected every six years and

pumped at least every eight years by a licensed

sewage hauler.

U. [Formerly paragraph A:1.21 of Appendix A]

Untreated or uncoated metal septic tanks shall not

be used.

V. [Formerly paragraph A:1.22 of Appendix A]

Abandoned septic tanks (tanks no longer in active

use) shall be pumped out by a licensed sewage

hauler, then removed or the cover discarded and

the tank filled with soil to natural grade. The

contents of the abandoned tank shall not be placed

into a newly installed individual sewerage system.

§717. Septic Tank Effluent

[formerly Section II of Appendix A]

A. [Formerly paragraph A:2.1 of Appendix A]

There is a common belief that sewage after

treatment in a septic tank is pure water, or very

nearly so. This is false. The effluent or liquid flowing

from the tank is still foul and dangerous. The septic

tank cannot be depended upon to remove disease

germs. The discharge of the effluent from septic tanks

into street gutters, surface ditches, or streams is

prohibited.

B. [Formerly paragraph A:2.2 of Appendix A] The

treatment level of a septic tank is referred to as primary

treatment.

C. [Formerly paragraph A:2.3 of Appendix A] The

preferred method of treatment for septic tank effluents

is accomplished through the use of soil absorption

trenches. Small oxidation ponds or sand filter beds may

be used in lieu of absorption trenches only where soil

and drainage conditions or available space prevent the

use of absorption trenches. The level of treatment of

these units is referred to as secondary treatment.

D. [Formerly paragraph A:2.4 of Appendix A] The use

of absorption trenches, oxidation ponds and filter beds

for the treatment of septic tank effluents is discussed in

detail in the following Paragraphs of these standards.

AUTHORITY NOTE: Promulgated in accordance with R.S. 40:4(A)(6)

and R.S. 40:5(9)(20).

HISTORICAL NOTE: Promulgated by the Department of Health and

Hospitals, Office of Public Health, LR 28:1349 (June 2002).

§719. Absorption Trenches

[formerly Section III of Appendix A]

A. [Formerly paragraph A:3.1 of Appendix A] Where

soil conditions are satisfactory and sufficient land is

available, septic tank effluent shall be disposed of in

absorption trenches. This consists of a system of covered

gravel (or other approved aggregate) filled trenches into

which the septic tank effluent is applied so as to permit

the liquid to seep into the soil. By action of

microorganisms in the soil, the organic matter is

converted into mineral compounds.

B. [Formerly paragraph A.3.2 of Appendix A] A

number of variables determine whether an absorption

trench is feasible, including: soil porosity (permeability),

ground water table, available space, and the rate at

which septic tank effluent enters the soil (percolation

rate). In general three conditions should be met.

1. The soil percolation rate must be within the

acceptable range.

2. The maximum elevation of the ground water

table should be at least 2 feet below the bottom of the

proposed trench system.

3. Clay formations or other impervious strata

should be at a depth greater than 4 feet below the

bottom of the trenches.

C. [Formerly paragraph A.3.3 of Appendix A]

Unless these conditions are satisfied, the site is

unsuitable for a subsurface sewage disposal system,

and an alternative method must be utilized.

D. [Formerly paragraph A.3.4 of Appendix A] The

acceptability of soil for an absorption trench system

and the required size of such a system is currently

based upon the "Percolation Test" described below.

1. Three or more tests must be made in

separate test holes spaced uniformly over the

proposed absorption field site.

2. Dig or bore a hole, with horizontal

dimensions of from 4 to 12 inches and vertical sides

to the depth of the proposed absorption trench. In

order to save time, labor, and volume of water

required per test, the holes may be bored with a 4-

inch auger.

3. Carefully scratch the bottom and sides of

the hole with a knife blade or sharp-pointed

instrument in order to remove any smeared soil

surfaces and to provide a natural soil interface into

which water may percolate. Remove all loose

material from the hole.

4. To conduct the test, fill the hole with clear

water. This pre-wetting procedure should normally

be accomplished on the day prior to the percolation

rate measurement. This procedure is to insure that

the soil is given ample opportunity to swell and to

approach the operating condition of the wet season

of the year. Thus, the test should give comparable

results in the same soil whether made in a dry or in

a wet season.

5. With the exception of sandy soils,

percolation rate measurements shall be made on

the day following the procedure described under

§719.D.4 above. Add water until the liquid depth is

at least 6 inches, but not more than 12 inches from

a fixed reference point. Measure the drop in water

level over a 60-minute period. This drop is used to

calculate the percolation rate. Section 1501.B.1

(Figure 1) shows methods of percolation rate

measurement. If the drop in liquid depth in the first

30 minutes is less than one inch, it is unnecessary to

continue the test for the full 60-minute period.

6. The distance the water falls in 60 minutes in

each of the three test holes is recorded. The average

drop for the three holes is used to determine the

total length of absorption trench from Table 1 below.

*-or per 150 gpd of design flow for non-residential applications.

E. [Formerly paragraph A:3.5 of Appendix A] Many

different designs may be used in laying out an absorption

trench system. The choice will depend on the size and

shape of the available disposal area, the capacity

required and the topography of the area.

F. [Formerly paragraph A:3.6 of Appendix A] The

septic tank effluent is applied to the absorption field

through a system of level bottomed trenches.

Conventional field lines are laid on a slope of 2 to 3

inches per 100 feet. Gravelless pipe and other

distribution chambers must be laid as close as possible to

a slope of 1 inch per 100 feet. A distribution box may be

required for equal distribution of the effluent. Section

1501.B.2 and 3 (Figure 2 and 3) show a typical layout of a

conventional absorption trench system for flat and

sloping areas.

G. [Formerly paragraph A:3.7 of Appendix A] To

provide the minimum required backfill depth and earth

cover, the depth of the absorption trenches must be a

minimum of 18 inches. Additional depth may be needed

for contour adjustment for extra backfill under the

distribution line or for other design purposes. However,

the total depth must not exceed 24 inches.

H. [Formerly paragraph A:3.8 of Appendix A] Careful

construction is important in obtaining a satisfactory soil

absorption system. Section 1501.B.4 (Figure 4) shows

details for absorption trench construction.

I. [Formerly paragraph A:3.9 of Appendix A]

Individual trenches shall not be greater than 100 feet in

length and not less than 18 inches in width. The center

line distance between individual trenches shall be at

least 6 feet. In addition, the absorption trenches

shall be located at least 10 feet from any dwelling or

property line.

J. [Formerly paragraph A:3.10 of Appendix A]

The location of the absorption trenches shall

comply with minimum distance requirements from

water wells, water lines, etc., as contained in Part XII

of this Code.

K. [Formerly paragraph A:3.11 of Appendix A] In

every case, at least two trenches shall be used.

L. [Formerly paragraph A:3.12 of Appendix A]

Trench bottoms must be level to promote even

distribution, thereby minimizing premature failure

of a portion of the trench. During excavation,

attention must be given to the protection of the

soil. Care must be taken to prevent sealing of the

surface on the bottom and sides of the trench.

Trenches should not be excavated when the soil is

wet enough to smear or compact easily. All smeared

or compacted surfaces must be raked to a depth of

1 inch and loose material removed before the

backfill is placed in the trench.

M. [Formerly paragraph A:3.13 of Appendix A]

Conventional field lines shall consist of perforated

non-metallic pipe meeting one of the following

standards.

PVC sewer pipe and fittings (Thin wall), ASTM D2729-93

Smooth wall polyethylene (PE) pipe, ASTM F810-93, for use in

waste disposal absorption fields;

SRP pipe and fittings, ASTM D2852-93.

1. In every case, the minimum acceptable

diameter is

4 inches. Although the trench bottom is level,

conventional field pipes must be laid on a slope of

between 2 to 3 inches per 100 feet to provide even

distribution of the liquid throughout the trench.

N. [Formerly paragraph A:3.14 of Appendix A]

Where conventional field pipe is used, it must be

surrounded by clean graded gravel or rock, broken,

hard-burned clay brick or similar material. The bed

material may range in size from

1/2 inch to 2.5 inches. The gravel must extend from

at least

2 inches above the top of the pipe to at least 6

inches below the bottom of the pipe. The top of the

stone should be covered with either untreated

building paper, or similar pervious material to

prevent the gravel from becoming clogged by the earth

backfill [see §1501.B.4 (Figure 4)].

O. [Formerly paragraph A:3.15 of Appendix A] Where

gravelless pipe or distribution chambers are used, the fill

must be porous soil or sand which allows the passage of

water in

all directions with a 6-inch layer below the pipe and filled

4 to 6 inches above grade and spread 3 to 4 feet on

either side of the trench. Only gravelless pipe or other

distribution chambers specifically approved for use in

Louisiana by the state health officer may be used. The

total length of gravelless distribution products required is

the same as for conventional absorption trenches.

P. [Formerly paragraph A:3.16 of Appendix A] For an

absorption trench to work properly, it must have access

to air, generally through the soil interstices of the

backfill. Therefore, the absorption trench should be

backfilled with 4 to 12 inches of pervious soil, hand-

tamped and then overfilled with about

4 to 6 inches of earth. Care should be taken to avoid

compacting of the backfill.

Q. [Formerly paragraph A:3.17 of Appendix A] All of

the above listed requirements, with the exception of the

protection of water supplies, are aimed at preventing

absorption trench clogging and premature failure. In

addition, the septic tank should be inspected every six

years after installation and pumped, as necessary, to

prevent solid overflow to the soil absorption system and

subsequent clogging and failure.

R. [Formerly paragraph A:3.18 of Appendix A]

Absorption trenches shall not be located:

1. beneath driveways, parking or other paved

areas;

2. in areas that may be subjected to passage or

parking of heavy equipment or vehicles, or storage of

materials;

3. beneath buildings or other structures.

§721. Oxidation Ponds

[formerly Section IV of Appendix A]

A. [Formerly paragraph A:4.1 of Appendix A] An

oxidation pond is a shallow pond designed specifically to

treat sewage by natural purification processes under the

influence of air and sunlight. The stabilization process

consists largely of the interactions of bacteria and algae.

Bacteria digest and oxidize the constituents of

sewage and render it harmless and odor free. Algae

utilize carbon dioxide and other substances

resulting from bacterial action and through

photosynthesis produce the oxygen needed to

sustain the bacteria in the treatment process.

During the detention period, the objectionable

characteristics of the sewage largely disappear.

B. [Formerly paragraph A:4.2 of Appendix A] The

minimum surface area of an oxidation pond must be

no less than 400 square feet with a 4 to 5 foot

average liquid depth and vertical side walls. This

minimum size pond is adequate for design flows of

up to 400 gallons/day (gpd). For design flows in

excess of 400 gpd, the pond area must be increased

to provide sufficient volume (at the 4 foot depth) to

hold 30 days worth of flow (a 30-day retention

period). For wastes with high BOD loadings, special

consideration for increasing pond size must be

given.

C. [Formerly paragraph A:4.3 of Appendix A]

Section 1501.B.5 (Figure 5) shows a typical layout

for a septic tank-oxidation pond system. The actual

layout of any pond system will be governed to a

great extent by the topography of the particular

location. However, an oxidation pond must be

located so as to comply with the minimum distance

requirements from water wells, lines, etc., as

contained in Part XII of this Code. It is also desirable

for aesthetic reasons to locate it as far as possible,

but at least 50 feet from any dwelling and no less

than 20 feet from the property line to water's edge

at normal operating line.

D. [Formerly paragraph A:4.4 of Appendix A] As

mentioned, the use of the minimum surface area of

400 square feet requires that an oxidation pond be

furnished with vertical side walls so that an

adequate volume for treatment is provided. Section

1501.B.6 (Figure 6) shows a type of construction

utilizing treated timber which under normal soil

conditions is acceptable for the vertical side walls of

a 20 foot by 20 foot oxidation pond with a 5 foot

average water depth. Section 1501.B.7 (Figure 7)

shows a similar type of construction utilizing

concrete blocks. Either of these designs requires

very little maintenance.

E. [Formerly paragraph A:4.5 of Appendix A]

Vertical side walls must be of cypress or treated

timbers or concrete blocks and so constructed as to

provide a permanent structure.

F. [Formerly paragraph A:4.6 of Appendix A]

Although not encouraged, a pond may be constructed

with sloping sides and earthen levees. Such a design is

shown in §1501.B.8 (Figure 8). The design requires a

minimum surface area of 625 square feet with a 5 foot

liquid depth at the center in order to achieve the

required volume. The cost of this design is less than that

of the vertical wall ponds referred to above, but more

space is needed and routine maintenance requirements

such as levee mowing are greater. The slope of the

natural earth side walls must not be shallower than one-

to-one (45-degree angle) [see §1501.B.8 (Figure 8)].

G. [Formerly paragraph A:4.7 of Appendix A] A septic

tank must precede the oxidation pond and must comply

with the septic tank requirements presented in these

regulations.

H. [Formerly paragraph A:4.8 of Appendix A] The pipe

from the septic tank to the pond as well as the outfall

pipe from the pond must be at least 4 inches in diameter

and placed at a minimum slope of 2 inches per 100 feet.

The inlet must extend 4 to 6 feet horizontally into the

pond and be directed downward at least 1 1/2 to 2 feet

below the liquid surface level. The outlet must extend 4

to 6 feet horizontally into the pond and consist of a tee

with the invert set at the operating water level of the

pond. One leg of tee must be open and extend above the

water level, while the down leg is extended 1 1/2 to 2

feet below the water level. The invert of the pond outlet

must be lower than the pond inlet invert [see §1501.B.8

(Figure 8)]. Additionally the invert of the pond inlet must

be at least 2 inches lower than the invert of the septic

tank outlet.

I. [Formerly paragraph A:4.9 of Appendix A] The

pond shall be enclosed by a suitable non-climbable fence

to keep out children, pets and livestock. An open type

fence (woven wire) is preferable because it will not

restrict sunlight and air which are necessary for the

treatment. The fence shall be at least

5 feet in height and be provided with a locked gate.

J. [Formerly paragraph A:4.10 of Appendix A]

Abandoned oxidation ponds (ponds no longer in active

use) shall be dewatered, allowed to dry and then filled

with soil to natural grade.

§723. Sand Filter

[formerly Section V of Appendix A]

A. [Formerly paragraph A:5.1 of Appendix A]

Another alternative for the secondary treatment of

septic tank effluent is a deep-type sand filter bed.

Treatment in a sand filter bed is accomplished by

the action of microorganisms in a sand bed in which

the suspended solids of the septic tank effluent

have been trapped by filtration. It is important that

the sand bed remain aerobic throughout the

treatment process. This is accomplished by exposing

the sand surface to the air as much as possible on a

continuous basis. Of course, the best way this can

be done is to place no cover whatsoever over the

sand bed. Since this is not aesthetically desirable for

homes, a coarse gravel cover of clean, washed

gravel, not to exceed 6 inches in depth over the bed

is permitted. No other cover is acceptable. A filter

bed system is shown in §1501.B.9 (Figure 9).

B. [Formerly paragraph A:5.2 of Appendix A] The

sand filter bed is constructed by placing perforated

pipe near the bottom of a rectangular area of the

required size in a layer of gravel covered by a layer

of coarse sand 24 inches deep. On top of this are

placed distribution lines (perforated pipe) likewise

encased in a layer of gravel [see §1501.B.10 (Figure

10)]. The septic tank effluent is distributed speedily

in the gravel cover spreading over the top of the

sand seeping slowly and vertically through the sand

to the bottom layer of gravel to be carried away in

the under drain line.

C. [Formerly paragraph A:5.3 of Appendix A]

Sand filter beds are to be constructed with a

minimum width of 12 feet and a minimum length of

25 feet. This minimum size filter bed is adequately

sized for design flows of up to 400 gpd. For greater

design flows, the required length shall be increased

by eight feet for each additional 150 gpd or portion

thereof.

D. [Formerly paragraph A:5.4 of Appendix A] The

bed must be drained completely. This may require

the bed to be raised above natural ground level.

E. [Formerly paragraph A:5.5 of Appendix A] To

prevent sand infiltration into the underdrain, a layer

of graded gravel must be placed over the

underdrain line and the entire bottom of the filter

bed. All gravel must be clean and washed.

F. [Formerly paragraph A:5.6 of Appendix A] Filter

sand shall conform to the following standard

specifications.

must be 4-inch diameter, 20-inch long farm tile, 2 feet to

3-feet lengths of vitrified clay bell-and-spigot sewer pipe

laid with open joints, or perforated nonmetallic pipe

meeting one of the standards cited in §719.M. The ends

of the distribution lines must be half-closed [see

§1501.B.10 (Figure 10)].

H. [Formerly paragraph A:5.8 of Appendix A]

Underdrain pipe materials are the same as those for the

distribution pipe, however, the slope must be no less

than 4 inches per 100 feet.

I. [Formerly paragraph A:5.9 of Appendix A] The

filter bed must be appropriately protected from surface

runoff water.

J. [Formerly paragraph A:5.10 of Appendix A] The

filter bed must be located no less than 10 feet from the

property line.

K. [Formerly paragraph A:5.11 of Appendix A] The

location of the filter bed shall comply with minimum

distance requirements from water wells, water lines,

etc., as contained in Part XII of this Code.

be disinfected, and chlorine is used as the disinfectant, a

chlorine contact chamber is required. Calcium

hypochlorite, labeled for wastewater disinfection, shall

be added in sufficient concentrations to maintain a

minimum residual of 0.5 ppm total chlorine in the

effluent. In order to achieve the required chlorine

contact time, a baffled chlorine contact chamber

[§1501.B.11 (Figures 11, 12, 13)] designed to meet the

needs for each system with the specified liquid holding

capacity shall be used as follows.

Disinfectant Chamber Minimum Liquid Capacity

Treatment Capacity of

Sewerage System

Contact Chamber

500 GPD or less

30 gallons

501-750 GPD

45 gallons

751-1000 GPD

60 gallons

1001-1500 GPD

90 gallons

1. Any other disinfectant proposed for use should

provide an equivalent level of disinfection.

B. [Formerly paragraph A:9.2 of Appendix A] Pumping

Stations. Pumping station, when required, must be

constructed of approved materials, and must comply

with the applicable provisions of this Code.

C. [Formerly paragraph A:9.3 of Appendix A] Effluent

Reduction Systems. Individual sewage systems, with a

capacity up to and including 1500 gpd, that produce

a treated, off-site effluent, shall include an effluent

reducer as part of the overall system [§1501.B.12

(Figure 14)].

D. [Formerly paragraph A:9.4 of Appendix A]

Special situations may arise where an individual on-

site wastewater treatment system is allowed as per

§511.B of this Code, but it is physically impossible to

install the required size of the effluent reduction

system or the effluent reduction system itself due to

lot size or when a limited use sewerage system is

installed in a marsh/swamp area or located over

water. The size of the effluent reduction system can

be reduced to the maximum amount the lot can

accommodate or the installation waived with the

authorization of the sanitarian parish manager.

Written notification of such authorization must be

submitted to the sanitarian regional director and a

copy attached to the "Application for Permit for

Installation of On-Site Wastewater Disposal System"

(LHS-47).

E. [Formerly paragraph A:9.5 of Appendix A] All

effluent reduction systems shall be installed by a

licensed installer. Existing field lines can not be used

as the effluent reduction system.

F. [Formerly paragraph A:9.6 of Appendix A] The

size of the effluent reduction system installed has to

correspond with the recommended size of the

sewerage system. For example if a 750 GPD plant is

required on the "Application For Permit For

Installation of On-Site Wastewater Disposal System"

(LHS-47), the applicant may install a 1000 GPD

plant, however the size of the effluent reduction

system only has to correspond to the minimum size

required for a 750 GPD plant.

G. [Formerly paragraph A:9.7 of Appendix A] The

sample port for a sewerage system must be installed

immediately downstream of the system and in

accordance with the appropriate edition and

Section of NSF Standard 40, as currently

promulgated, as well as the applicable provisions of

this Code.

100 feet in length. Clam or oyster shells may be

substituted for gravel in the effluent reduction field.

If used, gravel must be clean, graded and 1/2-inch

to 2 1/2 inches in diameter. Other media may be

considered for use if determined to have acceptable

characteristics and properties. Although it may not

be noted in the attached figures (§1501.B.1-19), the

end of the discharge line must have a 1/2 diameter

PVC end cap over the lower half of the endpipe,

causing longer retention of the effluent and

providing greater opportunity for absorption. If the

end of the discharge line is more than 2 inches

lower than the absorption line, other provisions

must be made to cause the effluent to be retained

in the reduction field.

12. [Formerly paragraph A:9.8-13 of Appendix

A] Gravelless pipe or other distribution chambers

may be used in lieu of conventional soil absorption

pipe. If gravelless pipe is used, the fill must be

porous soil or sand which allows the passage of

water in all directions, with a 6-inch layer below the

pipe and filled 4 to 6 inches above grade and spread

3 to 4 feet on either side of the trench.

B. [Formerly A:9.9-1 of Appendix A] Rock-Plant

feet from any property line. In addition, the RPF location

shall comply with the minimum distance requirements

from water wells and suction lines, water pressure lines,

etc., as contained in Parts XII and XIV of this Code.

3. [Formerly paragraph A:9.9-4 of Appendix A] If

there is not sufficient grade to install the sewerage

system and the rock plant filter with gravity flow to the

discharge point, then a pumping station in compliance

with applicable provisions of this Part must be installed.

4. [Formerly paragraph A:9.9-5 of Appendix A] In

order to prevent backflow, a backwater valve is required

whenever the discharge line is less than 12 inches above

the ditch flow-line.

5. [Formerly paragraph A:9.9-6 of Appendix A] Only

a standard shape bed may be installed with a minimum

width of 5 feet and of such length as to provide the

required square footage.

6. [Formerly paragraph A:9.9-7 of Appendix A]

Plans for any other configuration must be submitted for

review and approval to the sanitarian regional director.

7. [Formerly paragraph A:9.9-8 of Appendix A] A

liner will be required when the ground water level is

within 24 inches of the bottom of the trench.

8. [Formerly paragraph A:9.9-9 of Appendix A] The

polyethylene liner may be of more than one layer

provided a total thickness of 16 mil is achieved.

9. [Formerly paragraph A:9.9-10 of Appendix A]

When a liner is not required, the use of landscape fabric

is highly recommended to prevent weed intrusion.

10. [Formerly paragraph A:9.9-11 of Appendix A] The

bottom of the bed must be level and be no deeper than

14 inches.

11. [Formerly paragraph A:9.9-12 of Appendix A] A

depth of approximately 10 to 12 inches is best.

12. [Formerly paragraph A:9.9-13 of Appendix

A] Gravel must be 2-3 inches in diameter and laid to

a depth of 12 inches.

13. [Formerly paragraph A:9.9-14 of Appendix

A] An

8-inch water level must be maintained. Gravel

should fill the filter bed to above surface grade to

prevent erosion.

14. [Formerly paragraph A:9.9-15 of Appendix

A] The minimum 4-inch perforated inlet pipe must

be located no closer than 4 inches from the bottom

of the bed and supported by a footing of

noncorrosive material, such as concrete or treated

timber.

15. [Formerly paragraph A:9.9-16 of Appendix

A] The inlet should extend no more than 2 feet into

the rock plant bed and must be provided with a

"Tee" (with ends capped) extending the width of the

bed to within 1 foot of the side walls.

16. [Formerly paragraph A:9.9-17 of Appendix

A] The outlet pipe shall also be set in a footing of

noncorrosive material (concrete or treated timber)

on the bottom of the bed with the same "Tee" and

configuration. The outlet must be elbowed up and

out [§1501.B.14 (Figure 17)].

17. [Formerly paragraph A:9.9-18 of Appendix

A] Do not allow plants to grow within 3 feet of the

inlet and outlet of the bed.

18. [Formerly paragraph A:9.9-19 of Appendix

A] A levee support system around the perimeter of

the filter should be constructed to exclude surface

water. The use of landscape timbers for this purpose

is acceptable. Other materials, such as concrete, can

also be used.

C. [Formerly paragraph A:9.10-1 of Appendix A]

Spray Irrigation. The spray irrigation system

[§1501.B.15 (Figure 18)] uses an electric pump that

distributes the effluent to the yard through sprinkler

heads. It is highly recommended for spray irrigation

effluent to be chlorinated in a contact chamber,

sized according to §731.A, following the treatment

unit and preceding discharge. At a predetermined

level, a float switch activates a pump that forces the

effluent through piping to pop-up or elevated

rotating type sprinkler heads. Evaporation and soil

infiltration of the dispersed effluent should prevent

any run-off from occurring.

1. [Formerly paragraph A:9.10-2 of Appendix A] A

pump station system must be sized according to use and

comply with the applicable provisions of this Part.

2. [Formerly paragraph A:9.10-3 of Appendix A] The

pressure pump must be a minimum of one-half horse

power capable of producing a minimum flow of

12 gallons per minute and maintaining 25 pounds per

square inch at all sprinkler heads.

3. [Formerly paragraph A:9.10-4 of Appendix A] The

pump will be activated by a high/low water switch

through an automatic on/off switch. The pump must be

deactivated through a low-volume cut off switch.

4. [Formerly paragraph A:9.10-5 of Appendix A] A

time cycle device may be used to allow for specific

sprinkling times (e.g., nighttime, afternoon). The pump

chamber must be of adequate liquid capacity to allow

sufficient storage to accommodate the desired time

settings.

5. [Formerly paragraph A:9.10-6 of Appendix A] A

minimum of three 4-inch type sprinkler heads coded for

wastewater effluent, spaced a minimum of 40 feet apart

are required.

6. [Formerly paragraph A:9.10-7 of Appendix A] The

spray irrigation sprinklers shall comply with American

Society of Agricultural Engineers (ASAE) Standard S 398.1

(Procedure for Sprinkler Testing and Performance

Reporting).

7. [Formerly paragraph A:9.10-8 of Appendix A] The

slope of the land shall be such as to facilitate drainage

away from any water well or well suction lines. The edge

of the spray and its drainage must be a minimum of 50

feet from any private water well and its associated

suction lines and 10 feet from any property line. The

edge of the spray and its drainage shall be a minimum

100 foot from public any water supply well and its

associated suction lines, if any. In addition, the edge of

the spray and its drainage shall be a minimum of 25 feet

from any potable water (pressure) lines. As contained in

Parts XII and XIV of this Code.

8. [Formerly paragraph A:9.10-9 of Appendix A]

Exceptions due to lot size, topography or other

constraints may be authorized by the sanitarian parish

manager with written notification of such authorization

to the sanitarian regional director and a copy attached to

the LHS-47.

D. [Formerly paragraph A:9.11-1 of Appendix A]

Overland Flow. When the size of the property is 3 acres

or more, an overland flow may be utilized

[§1501.B.16 (Figure 19)].

1. [Formerly A:9.11-2 of Appendix A] The

discharge through perforated pipe must be

distributed in such a manner as to confine the

effluent on the property owned by the generator.

2. [Formerly A:9.11-3 of Appendix A] The

location of the overland discharge must have a

permanent vegetative cover.

3. [Formerly A:9.11-4 of Appendix A] The slope

of the land shall be such as to facilitate drainage

away from any water well or well suction lines. The

discharge point and the field of flow shall be a

minimum of 50 feet from any private water well and

its associated suction lines. The discharge point and

the field of flow shall be a minimum 100 foot from

public water supply wells and its associated suction

lines, if any. In addition, the discharge point and the

field of flow shall be a minimum of 25 feet from any

potable water (pressure) lines. As contained in Parts

XII and XIV of this Code.

4. [Formerly A:9.11-5 of Appendix A] A header

should be used at the end of the discharge line to

help disperse the effluent and to discourage

channelization. The point of discharge must be such

that there is at least a 200 foot flow of effluent over

the property of the generator.

5. [Formerly A:9.11-6 of Appendix A]

Construction of the system should be such that it is

not closer than

20 feet from the property line.

E. [Formerly A:9.12 of Appendix A] Mound

System or Subsurface Drip Disposal [§1501.B.17 and

18 (Figures 20 and 21)]. Either can be considered by
