or in the future. A gas deflection baffle or other acceptable outlet modification, and c dual
compartment tank or two tanks in series must also be provided.
B. Multi -compartment tanks or tanks in series.
a. Dual compartments are recommended for all tanks and shall be required on all torks with an
interior length of ten feet or more.
b. The first compartment or tank (inlet side) shall account for 60 - 757. of the required total
design volume.
c. The baffle separating the compartments shall extend from the bottom of the tank -:o at least
six inches above the invert of the outlet pipe.
d. Compartments shall be connected by a four inch vertical slot at least 18 inches in width, a six
inch elbow, or two 4 -inch elbows located at a distance below the liquid level equal tc
one-third the distance between the invert of the outlet and the bottom of the tank. /.t least
one access manhole shall be provided into each compartment.
e. Tanks in series should be connected by a single pipe with a minimum diameter of four
inches.
F. The volume and surface area for meeting the requirements of the design shall be based upon the
total volume and surface areas of all the tanks and chambers to be installed.
C. Concrete tanks.
a. Concrete shall have a minimum compressive strength of 2,500 pounds per square nch (psi)
at 28 days set; 3,000 psi concrete is recommended as a minimum.
b. Wall thickness shall be a minimum of three inches unless the design has been cer ified by a
New York licensed professional engineer as complying with all appropriate requirements
for thin-wall construction. All walls, bottom and top shall contain reinforcing to assure
support for 300 psf.
c. All joints shall be sealed such that the tank is watertight, joints below the liquid le gel must be
tested for watertightness prior to backfilling.
d. The walls and floor of cast -in-place tanks shall be poured at the some time (monolithic pour).
D. Fiberglass and polyethylene tanks. These tanks must meet the following additional requi-ements:
a. These tanks shall not be installed in areas where the groundwater level can rise to the level of
the bottom of the septic tank.
b. Particular care must be taken during installation, bedding, and backfilling of these units so as
to prevent damage to tank walls. The manufacturer's installation instructions shall be
followed.
c. All tanks should be sold by the manufacturer completely assembled. If, because of size, the
tank is delivered to the site in sections, all joints shall be sealed with watertight gaskets

House Sewer
1. House sewers are laid on firm foundation at a minimurn grade of one-quarter inch per foot preferably
without bends. At least one cleanout with a properly fitted plus: is to be provided. The house sewer shall
allow for venting of gases from the sewage system.
2. House sewer construction including materials shall comply with the applicable requirements of the State
Uniform Fire Prevention and Building Code contained in 9 NY6RR, Parts 903 through 907, inclusive,
and Part 1250.
3. A minimum horizontal separation of 10 feet should exist between the house sewer and any water line.
Where lines must cross, the water service line shall be at least 12 inches above the house sewer. If a
water line must pass below the house sewer, the vertical separation must be at least 18 inches.
4. Suction waterlines shall never cross under house sewers or any other component of the sewage system.
Distribution Devices
1. Gravity Distribution. The maximum length of absorption lines used in conjunction with gravity distribution
shall be 60 feet.
A. Distribution Box.
a. For accessibility, it is necessary that the distribution box be located and have a removable
cover not more than 12 inches below grade. Where, due to site conditions, a distribution
box must be greater than 12 inches below the surface, an extension collar sholl be
installed to within 12 inches of the surface.
b. All outlets from the distribution box shall be at the some level to insure the even distribution
of flow.
c. To minimize frost action and reduce the possibility of movement once insta'.d, distribution
boxes must be set on a bed of sand or pea gravel at least 12 inches thick.
d. The drop between inlet and outlet inverts shall be at least two inches. A baffle is required at
the inlet side of the box when the slope from the septic tank to the box exceeds 1/2 inch
per foot or when siph,. n dosin.a is used.
e. There shall be a minimum two inch clearance between the inverts of the ou'lets and the
bottom of the box to prevent short-circuiting and reduce solids carry-over.
f. Distribution boxes may be constructed in place or purchased prefabricated. When concrete is
used to construct boxes, it shall have a minimum compressive strength of 2,500 psi at 28
day set.
g. Prefabricated boxes may be constructed of concrete, fiberglass, or plastic. The boxes shall be
installed in conformance with the manufacturer's instructions in addition to the
requirements above.
Absorption Field Systems.
A. Site requirements.
a. The minimum distances that absorption fields shall be separated from other facilities ore
shown in the table provided.
b. A minimum of four feet of useable soil shall exist above bedrock and groundwater with a
minimum separation of two feet to the lowest part of any trench.
c. Absorption fields shall not be built under driveways, parts of buildings or ur der above-
ground swimming pools or other areas subject to heavy loading. Surface waters shall be
diverted from the vicinity of the system.
B. Design criteria.
a. The required length of absorption trench is determined from the percolation test results
and confirmed by the on site soil evaluation. The maximum trench width for design
purposes shall be 24 inches.
b. Adjacent trenches shall be separated by at least four feet of undisturbed soi. Individual
trenches shall be constructed parallel to the ground contours with trench bottoms as near
level as possible. They need not be perfectly straight but abrupt changes in direction shall
be avoided.
C. Materials.
a. Perforated distributor pipe shall be used in the trenches. Solid (non -perforated) pipe shall be
used between the distribution box and the trenches. Perforated pipe shall be made of rigid
or corrugated plastic and be labeled as fully meeting ASTM standards for use in septic
systems. Corrugated plastic pipe delivered in coils is not to be used unless provision is
made to prevent the recoiling or movement of the pipe after installation.
b. Aggregate shall mean washed gravel or crushed stone 3/4- 1 1/2 inches in diameter. Larger
diameter material or finer substances and run -of -bank gravel are unacceptable.
c. The aggregate shall be covered with a material that prevents soil from entering the aggregate
after backfilling, yet must permit air and moisture to pass through. The preferred material
for covering the aggregate is a permeable geotextile. Untreated building paper or a four
inch layer of hay or straw is acceptable. Polyethylene and treated building paper are
relatively impervious and shall not be used.
D. Construction.
a. Trench locations and depths should be marked by stakes before the trenches are excavated.
b. The natural surface shall not be significantly disturbed. If the site is regraded or similarly
disturbed, the soil shall be allowed to stabilize and new percolation tests conducted.
c. The trench depth shall be as shallow as possible, but not less than 18 inches. At least six
inches of aggregate is placed below the distribution line and two inches above tine line.
d. The earth cover over the aggregate should not exceed 12 inches in order to enhance
natural aeration and nitrogen uptake by plant life. Trenches shall be excavated tr design
depth with bottoms practically level. Heavy equipment shall be kept away from the field
because the weight may permanently alter soil characteristics due to compaction, cause
trench cave-ins, and/or misalign and break pipe.
e. Trench bottoms are to be raked and immediately covered with at least six inches of aggregate.
Any smeared surfaces on the trench walls are to be raked. Distributor lines are carefully
placed on the aggregate and covered with aggregate to a depth of at least two inches over
the top of the pipe. Additional aggregate may be required to bring the top of the aggregate
to within six to 12 inches of the surface.
f. in gravity distribution systems, the pipe shall be carefully sloped at between 1/16 inch and
1/32 inch per foot. Grades shall be determined by an engineer's level, transit or carpenter's
level.
g. After the upper aggregate is placed, the geotextile, untreated building paper, hay or straw is to
be immediately installed and the trench backfilled with native soil. If the trenches cannot
be immediately backfilled, they should be temporarily covered with an impervious
material such as treated building paper to prevent sidewall collapse and siltation into the
aggregate.
h. The earth backfill is to be mounded slightly above the original ground level to allow for
settling and after settlement the entire area should be graded without the use oi` heavy
equipment and seeded with grass.

a. For accessibility, it is necessary that the distribution box be located and have a removable
cover not more than 12 inches below grade. Where, due to site conditions, a distribution
box must be greater than 12 inches below the surface, an extension collar sholl be
installed to within 12 inches of the surface.
b. All outlets from the distribution box shall be at the some level to insure the even distribution
of flow.
c. To minimize frost action and reduce the possibility of movement once insta'.d, distribution
boxes must be set on a bed of sand or pea gravel at least 12 inches thick.
d. The drop between inlet and outlet inverts shall be at least two inches. A baffle is required at
the inlet side of the box when the slope from the septic tank to the box exceeds 1/2 inch
per foot or when siph,. n dosin.a is used.
e. There shall be a minimum two inch clearance between the inverts of the ou'lets and the
bottom of the box to prevent short-circuiting and reduce solids carry-over.
f. Distribution boxes may be constructed in place or purchased prefabricated. When concrete is
used to construct boxes, it shall have a minimum compressive strength of 2,500 psi at 28
day set.
g. Prefabricated boxes may be constructed of concrete, fiberglass, or plastic. The boxes shall be
installed in conformance with the manufacturer's instructions in addition to the
requirements above.
Absorption Field Systems.
A. Site requirements.
a. The minimum distances that absorption fields shall be separated from other facilities ore
shown in the table provided.
b. A minimum of four feet of useable soil shall exist above bedrock and groundwater with a
minimum separation of two feet to the lowest part of any trench.
c. Absorption fields shall not be built under driveways, parts of buildings or ur der above-
ground swimming pools or other areas subject to heavy loading. Surface waters shall be
diverted from the vicinity of the system.
B. Design criteria.
a. The required length of absorption trench is determined from the percolation test results
and confirmed by the on site soil evaluation. The maximum trench width for design
purposes shall be 24 inches.
b. Adjacent trenches shall be separated by at least four feet of undisturbed soi. Individual
trenches shall be constructed parallel to the ground contours with trench bottoms as near
level as possible. They need not be perfectly straight but abrupt changes in direction shall
be avoided.
C. Materials.
a. Perforated distributor pipe shall be used in the trenches. Solid (non -perforated) pipe shall be
used between the distribution box and the trenches. Perforated pipe shall be made of rigid
or corrugated plastic and be labeled as fully meeting ASTM standards for use in septic
systems. Corrugated plastic pipe delivered in coils is not to be used unless provision is
made to prevent the recoiling or movement of the pipe after installation.
b. Aggregate shall mean washed gravel or crushed stone 3/4- 1 1/2 inches in diameter. Larger
diameter material or finer substances and run -of -bank gravel are unacceptable.
c. The aggregate shall be covered with a material that prevents soil from entering the aggregate
after backfilling, yet must permit air and moisture to pass through. The preferred material
for covering the aggregate is a permeable geotextile. Untreated building paper or a four
inch layer of hay or straw is acceptable. Polyethylene and treated building paper are
relatively impervious and shall not be used.
D. Construction.
a. Trench locations and depths should be marked by stakes before the trenches are excavated.
b. The natural surface shall not be significantly disturbed. If the site is regraded or similarly
disturbed, the soil shall be allowed to stabilize and new percolation tests conducted.
c. The trench depth shall be as shallow as possible, but not less than 18 inches. At least six
inches of aggregate is placed below the distribution line and two inches above tine line.
d. The earth cover over the aggregate should not exceed 12 inches in order to enhance
natural aeration and nitrogen uptake by plant life. Trenches shall be excavated tr design
depth with bottoms practically level. Heavy equipment shall be kept away from the field
because the weight may permanently alter soil characteristics due to compaction, cause
trench cave-ins, and/or misalign and break pipe.
e. Trench bottoms are to be raked and immediately covered with at least six inches of aggregate.
Any smeared surfaces on the trench walls are to be raked. Distributor lines are carefully
placed on the aggregate and covered with aggregate to a depth of at least two inches over
the top of the pipe. Additional aggregate may be required to bring the top of the aggregate
to within six to 12 inches of the surface.
f. in gravity distribution systems, the pipe shall be carefully sloped at between 1/16 inch and
1/32 inch per foot. Grades shall be determined by an engineer's level, transit or carpenter's
level.
g. After the upper aggregate is placed, the geotextile, untreated building paper, hay or straw is to
be immediately installed and the trench backfilled with native soil. If the trenches cannot
be immediately backfilled, they should be temporarily covered with an impervious
material such as treated building paper to prevent sidewall collapse and siltation into the
aggregate.
h. The earth backfill is to be mounded slightly above the original ground level to allow for
settling and after settlement the entire area should be graded without the use oi` heavy
equipment and seeded with grass.

a. Dual compartments are recommended for all tanks and shall be required on all torks with an
interior length of ten feet or more.
b. The first compartment or tank (inlet side) shall account for 60 - 757. of the required total
design volume.
c. The baffle separating the compartments shall extend from the bottom of the tank -:o at least
six inches above the invert of the outlet pipe.
d. Compartments shall be connected by a four inch vertical slot at least 18 inches in width, a six
inch elbow, or two 4 -inch elbows located at a distance below the liquid level equal tc
one-third the distance between the invert of the outlet and the bottom of the tank. /.t least
one access manhole shall be provided into each compartment.
e. Tanks in series should be connected by a single pipe with a minimum diameter of four
inches.
F. The volume and surface area for meeting the requirements of the design shall be based upon the
total volume and surface areas of all the tanks and chambers to be installed.
C. Concrete tanks.
a. Concrete shall have a minimum compressive strength of 2,500 pounds per square nch (psi)
at 28 days set; 3,000 psi concrete is recommended as a minimum.
b. Wall thickness shall be a minimum of three inches unless the design has been cer ified by a
New York licensed professional engineer as complying with all appropriate requirements
for thin-wall construction. All walls, bottom and top shall contain reinforcing to assure
support for 300 psf.
c. All joints shall be sealed such that the tank is watertight, joints below the liquid le gel must be
tested for watertightness prior to backfilling.
d. The walls and floor of cast -in-place tanks shall be poured at the some time (monolithic pour).
D. Fiberglass and polyethylene tanks. These tanks must meet the following additional requi-ements:
a. These tanks shall not be installed in areas where the groundwater level can rise to the level of
