operation and shall require the approval of the Town Engineer.
[Amended 10-13-1987 by L.L. No. 8-1987]
G.
Wherever septic tanks are approved for installation
to service business or commercial buildings, a tank of 750 gallon
net capacity shall be considered adequate for 15 employees and shall
be increased by 25 gallons for each additional employee.
H.
Where wastes contain oil, such wastes shall first
pass through an approved oil separator (minimum capacity 25 gallons)
placed at an easily accessible location.
I.
Drains through the foundation shall be of four-inch
cast-iron soil pipe laid at a minimum slope of 1/4 inch per foot and
shall extend a distance of at least 10 feet from the foundation to
the installed septic tank. The house sewer shall be vented through
the roof with at least a three-inch vent so that full circulation
of air is established at all times. If kitchen or other plumbing fixtures
are vented into the house sewer, the vent shall be increased to a
four-inch pipe through the roof. No roof leaders or floor or cellar
drains are to drain to septic tanks. Septic tank effluents shall be
disposed of by discharging to subsurface tile systems, seepage pits,
sand filter or by such other means as approved, in writing, by the
Town Engineer. Sewer lines to septic tanks and from septic tanks to
the leaching system shall be made watertight and protected from damage
by roots and other causes.
[Amended 1-25-1999 by L.L. No. 1-1999]
A.
All tests shall be made within the area of the proposed
sewage disposal system. At least two soil percolation tests shall
be made in separate test hold locations and at least one test pit
dug in the area proposed for the sewerage disposal system.
B.
All soil test results shall be certified by a professional
engineer licensed in the State of New York.
[Added 10-13-1987 by L.L. No. 8-1987]
C.
The procedure noted below shall be followed in performing
a soil percolation test:
(1)
Dig a hole with vertical sides and approximately 12
inches wide. If a tile trench field is being considered, the depth
of the percolation test holes shall be between 24 and 30 inches below
the final ground surface. If a seepage pit is under construction,
then percolation tests should be run at 1/2 the depth and at the full
estimated depth of the seepage pit. Small stones shall be placed in
the bottom of the test hole to reduce scouring and silting action.
(2)
Fill the test hole with water and allow it to completely
seep away. This in known as "presoaking" and must be done 24 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.
(3)
Pour clean water into the hole, with as little splashing
as possible, to a depth of six inches.
(4)
Observe and record the time in minutes required for
the water to drop one inch (from the six-inch to the five-inch mark.)
(5)
Repeat the test (a minimum of three times) until the
time for the water to drop one inch for two successive tests gives
equal results. The last test will then be taken as the stabilized
rate of percolation, and the time recorded for this test will be the
design basis for determining the square footage of leaching or absorption
areas required for a subsurface leaching system.
(6)
Percolation tests shall not be made in frozen or newly
made fill. In fill areas, tests may be made after a six-month settling
period or after other suitable stabilization. Test pits shall be excavated
at least two feet below the elevation of the proposed disposal system.
A soil log shall be maintained and depths to groundwater and rock
noted.
A.
Subsurface tile field shall be used where the more
porous natural earth is close to the surface where it is desired to
give private water supplies the maximum protection and where the porosity
shall not be less than one inch fall to 60 minutes.
B.
Dosing tanks shall be used in systems with over 500
feet of tile and shall be equipped with automatic siphons and have
a dosing capacity equal to 60% to 75% of the interior capacity of
the pipe in the portion of the subsurface tile system which is dosed
at one time. Where the total length of the tile laterals exceeds 1,000
feet, the dosing tank shall be provided with two siphons, each serving
1/2 the tile field and dosing in alternation. Standard siphons must
be used, but alternating service shall be specified. If inadequate
head is available to permit the use of siphons, a pump shall be substituted
for each siphon.
C.
Main distributors shall have diameters of not less
than four inches and be laid with tight joints on uniform slopes.
Where a dosing tank is used, the slope shall be 0.5% or 1/16 of an
inch per foot. Lateral distributors comprising the tile field shall
be four inches in diameter and shall be laid in trenches not less
than 24 inches wide and not less than 18 inches, nor more than 24
inches deep, depth less than 24 inches being preferable. The bottom
of the trenches and lateral distributors must be on a slope of 1/16
inch per foot or 1/32 inch per foot. The spacing between lateral distributors
shall be at least six feet. Where excessive slopes are encountered,
drop manholes shall be used on main distributors. Distributors shall
be agricultural drain tile, clay tile, bituminous fiber, rigid plastic
or corrugated plastic pipe. When perforated pipes are used, the holes
shall be placed down in such a manner that the liquid will escape
at an equal rate along the entire lateral. If the laterals are constructed
of agricultural drain tile or vitrified clay pipe they shall be laid
upon open joints 1/8 inch to 1/4 inch wide and protected with strips
of tar paper or other approved material laid over the top and 2/3
around the circumference of the pipe. All laterals shall be surrounded
by graded gravel or broken stone 3/4 to 1 1/2 inches in size
from a level of at least six inches below the bottom of the pipe to
a level of at least two inches above the top of the pipe. Before backfilling,
a single layer of building paper or a thick mat of hay or straw shall
be placed on top of the gravel or broken stone and across the full
width of the trench. The placing of distributors or laterals over
water service lines is prohibited. Curtain drains of suitable depth
and location shall be provided to intercept surface and groundwater,
and the tile field system shall be protected from damage by roots.
D.
Laterals shall not be nearer than 100 feet to any
lake, stream, watercourse or other body of water, unless approved
by the Orange County Department of Health, and must not be laid in
swampy soil or in soil that cannot adequately drain. The bottom of
tile field trenches shall be at least two feet above the maximum groundwater
table and at least two feet above solid rock or other impervious formation.
E.
A distribution box or chamber must be provided, into
which the septic tank effluent discharges and from which the sewage
enters the subsurface disposal field lines. The inlet pipe should
enter at the end of the box two inches above the outlets. The sides
of the box shall extend 12 inches above the invert of the inlet pipe,
and the box shall be provided with a removable cover. The cover of
the box shall be placed no more than 12 inches below the surface of
the ground. Drainage lines shall be constructed with inverts at the
bottom level of the box or one inch above the bottom, and all shall
be set at the same elevation. They shall run straight, all horizontal
bends shall be avoided and they should be made with tight joints.
When set at the same elevation and operating under the same head,
pipes all of the same size shall receive an equal flow. The box need
not be more than 18 inches in width, nor longer than is necessary
to accommodate the drain lines. Baffles shall be installed when directed
by the Town Engineer. When a series of distribution boxes are used,
the invert of the pipe leaving a box to carry effluent to the next
box shall be at least 1 1/4 inches higher then the invert of
the laterals from that same box.
[Amended 1-25-1999 by L.L. No. 1-1999]
F.
Tile field trenches shall be of approximately equal
length. The length of an individual trench shall not exceed 60 feet
to 100 feet where dosing siphons are used. The minimum total length
of tile field shall be 200 feet. The length of tile trenches shall
be calculated using the data contained in Table 2.

A.
Seepage pits may be installed where the top soil is
underlain with sand, gravel or similar natural porous material. They
shall be made of durable material and construction and of such proportions
that the side area is approximately three times the bottom area. The
flow of settled sewage to the seepage pits shall provide equal distribution
to each pit, the minimum distance between center of pits shall be
at least three times their diameter.
B.
The bottom of the seepage pits shall be at least two
feet above the maximum groundwater table and at least three feet above
solid rock or other impervious formation. A minimum of two pits shall
be installed and the distance between any two pits shall be at least
two times the larger pit diameter.
C.
The leaching area required for such installations
shall be determined by the results of percolation tests in accordance
with Table 3, but no permit will be issued for a seepage pit unless
the character of the soil in which it is to be located is such that
groundwater flow appears to be away from any adjoining property within
50 feet and away from any source of water supply. No permit shall
be issued for any seepage pit where, in the judgment of the Town Engineer,
such installations shall be dangerous to adjoining property.
[Amended 1-25-1999 by L.L. No. 1-1999]
D.
Details for seepage pits shall be submitted with the
application and shall be subject to approval by the Town Engineer.
[Amended 1-25-1999 by L.L. No. 1-1999]
E.
Effective leaching area shall be calculated as the
outside area of the pit below the inlet. The bottom area is not considered
in these calculations.
F.
A test showing a rate of percolation slower than one
inch in 60 minutes indicates that disposal of sewage by the subsurface
method is not suitable and that other methods of disposal are required.
