J. Diameter of circular tanks. No tank or compartment
thereof shall have an inside horizontal dimension less than 48 inches.
K. Inlets and outlets.
(1) Inlet and outlet connections of each tank or compartment
shall be arranged so as to obtain effective retention of scum and
sludge. An inlet baffle is not required when the tank is provided
with a vented pipe tee not less than four inches in diameter with
the bottom opening extending at least six inches below the surface
of the liquid, or as required by Commercial Standard 177-62 for metal
tanks. The invert elevation of the inlet shall not be less than one
inch (preferably three inches) above the invert elevation of the tank
outlet or the outlet of the first compartment.
(2) Outlet connections of the tank and of each compartment
thereof shall be provided with a tee not less than four inches in
diameter or a durable baffle equivalent in size. They shall be permanently
fastened in place with the bottom opening extending to a depth of
about 40% of the liquid depth. There shall be a clear space between
the top of baffle and the inside roof of tank of not less than one
inch.
L. Scum storage. The space between the liquid surface
and the top of the scum-retaining device on the outlet shall be not
less than 15% of the total required liquid capacity.
M. Access openings. In single-compartment tanks, an access
opening shall be located over the inlet. In multiple-compartment tanks,
access openings shall be located over each inlet and outlet. Access
to each compartment of the tank shall be by means of a sixteen-inch

shall be minimum diameter of four inches, and shall consist of a material
approved by the New York State Health Department.
O. Distribution.
(1) A distribution box shall be installed between septic
tanks and disposal fields or seepage pits. If only one seepage pit
is used, no distribution box is required. A dosing device shall be
provided where there are over 500 lineal feet of open-jointed or perforated
distribution lines.
(2) Distribution boxes shall be watertight, constructed
of concrete or an approved material and laid on a firm foundation.
They shall be so constructed as to provide equal distribution to the
disposal system. Distribution boxes shall be provided with a means
of access. The invert of the inlet shall be at least one inch above
the inverts of the outlets.
P. Disposal areas. The disposal area is the entire area
used for underground dispersion.
Q. Percolation tests.
(1) At least one percolation test shall be performed at
the site of each disposal area. More than one test will be required
where the soil structure may vary or large disposal areas are required.
(2) Tests shall not be made in filled ground unless the
soil has been compacted or allowed to settle to the satisfaction of
the health authority having jurisdiction.
(3) Percolation tests shall be performed in accordance
with the following procedure:
(a)
Dig a hole with vertical sides having a diameter
of approximately 12 inches. If a tile field is being considered, the
depth of the percolation test hole should be six inches below the
proposed trench bottom or approximately 30 inches below the final
ground surface. If a seepage pit or cesspool is under consideration,
then percolation tests should be run at 1/2 the depth and also at
the full estimated depth of the seepage pit. In order to facilitate
the running of the test, a larger excavation should be made for the
upper portion of the hole with the actual test hole in the bottom.
(b)
Fill the test hole with water and allow it to
completely seep away. This is known as presoaking and must be done
several hours before the test and again at the time of the test. After
the water has seeped away, remove any loose soil that has fallen from
the sides of the hole.
(c)
Pour clean water into the hole, with as little
splashing as possible, to a depth of six inches.
(d)
Observe and record the time in minutes required
for the water to drop one inch (from the six-inch to the five-inch
mark).
(e)
Repeat the test a minimum of three times until
the time for the water to drop one inch, for two successive tests
give approximately equal results. The last test will then be taken
as the stabilized rate of percolation and the time recorded for this
test will be used as the design basis for determining the square footage
of leaching or absorption area required for a subsurface system.
R. Minimum percolating area. The minimum required percolating
area per bedroom shall be determined from the following table:
|
Percolation Rate (time required for water
to fall one inch, in minutes)
|
Required Absorption Area in Square Feet

S. Subsoil and groundwater determination.
(1) Additional information will generally be required
relative to soil structure and groundwater elevations adjacent to
or below the proposed disposal area.
(2) The number of test borings or pits shall be made according
to satisfaction of the responsible health authority.
T. Disposal fields.
(1) Filter material. Filter material shall cover the distribution
lines and extend the full width of the trench or bed, shall not be

size from 1/2 to 2 1/2 inches, free of fines, dust, ashes or
clay. The filter material shall be covered by building paper or by
a two-inch layer of hay or straw.
(2) Distribution lines. Distribution lines shall be constructed
true to line grade. Agricultural tile, bituminized fibre, asbestos
cement or equally adequate pipe may be used. In case of agricultural
tile, openings between joints shall be 1/8 inch to 1/4 inch with the
upper half of the joint covered with treated paper.
(3) Backfill. Backfill over disposal trenches or beds
shall not be tamped and no grading machinery shall be permitted to
pass over the area.

(7) Backfill. The space between the excavation and seepage
pit wall shall be backfilled with at least six inches of coarse gravel
or crushed stone. Where cinder or concrete blocks are laid with core
openings exposed, the space between the excavation and seepage pit
wall shall be backfilled with at least six inches of two-and-one-half-inch
crushed stone or similar material.
(8) Covers. A watertight and structurally safe cover shall
be provided.
(9) Dry wells. Dry wells are permitted. A dry well may
be utilized to receive the drainage from roofs, basements or areaways,
provided its installation will not interfere with the operation of
the individual sewage-disposal system.
The provisions of this chapter shall apply to
reconstruction and repairs of existing septic systems; however, the
Engineering Technician II may vary the provisions of this chapter
if a variance is necessitated by hardship created by local physical
conditions.
The Engineering Technician II is authorized
to make necessary inspections to determine the satisfactory compliance
with this chapter. The owner or occupant shall give this official
or other enforcement official appointed by the Town Board in his absence
free access to the property at reasonable times for the purpose of
making such inspections. Failure to grant such access shall constitute
an automatic revocation of the disposal permit.
Any person may appeal to the Town's Zoning Board
of Appeals from the interpretation of any administrative decision
involving the interpretation of any provision of this chapter by filing
a written appeal within 10 days from such decision with the Town Clerk.
The Zoning Board of Appeals shall, on not less than three days' notice

not less than five days after such hearing, advise all interested
parties of its decision in writing.
Any person, persons, firm or corporation violating
any provision of this chapter shall be guilty of a violation which
shall be punishable by a fine of not more than $250, or by imprisonment
not to exceed 15 days, or both, and each day's failure to comply shall
constitute a separate violation. In case any septic disposal system
is constructed in violation of this chapter, or this chapter is otherwise
violated, the Town Board may also maintain an action or proceeding
in the name of the Town to compel compliance with or restrain by injunction
any violation of this chapter.
In any case where a provision of this chapter
is found to be in conflict with a provision of any zoning, building,
fire, safety or health ordinance or code of this Town, county or state
existing on the effective date of this chapter, the provision which,
in the judgment of the local health officer, establishes the higher
standard for the promotion of health and safety of the people shall
prevail. In any case where a provision of this chapter is found to
be in conflict with a provision of any other ordinance or code of
this Town, county or state existing on the effective date of this
chapter which establishes a lower standard for the promotion and protection
of health and safety of the people, the provisions of this chapter
shall be deemed to prevail, and such other ordinances or codes are
hereby repealed to the extent that they may be found in conflict with
this chapter.
