All extensions to the sanitary sewer system
owned and maintained by the Town shall be properly designed in accordance
with the Recommended Standards for Sewage Works, as adopted by the
Great Lakes Upper Mississippi River Board of State Sanitary Engineers
and in strict conformance with all requirements of the New York State
Department of Health. Plans and specifications for sewer extensions
shall be submitted to and approval obtained from the Engineer and
New York State Department of Health before construction may proceed.
The design of sewers must anticipate and allow for flows from all
possible future extensions or developments within the immediate drainage
area.
Sewer extensions, including individual building sewer laterals to the property line, may be constructed by the Town under public contract if, in the opinion of the Town Board, the number of properties to be served by such extension warrants its cost. Under this arrangement, the property owner shall pay for and install the building sewer from the property line to his residence or place of business in accordance with the requirements of Article IV. Thereafter, each property owner served by the extended public sewers will be charged at the full service charge rate as outlined in Article X. Property owners may, in accordance with applicable law, propose sewer extensions within the Highland Sewer District or other parts of the Town by drafting a written petition, signed by a majority of the benefiting property owners, and filing it with the Town Board.
If the Town does not elect to construct a sewer extension under public contract, the property owner, builder or developer may construct the necessary sewer extension if this extension is approved by the Town Board in accordance with the requirements of this article. He or they must pay for the entire installation, including all expenses incidental thereto. Each building sewer must be installed and inspected as required by this chapter, and the inspection fees shall be paid. Design of sewers shall be as specified in § 85-30. The installation of the sewer extension must be subject to full-time inspection by the Town Engineer, and the expenses for this inspection shall be paid for by the owner, builder or developer. The Town Engineer's decision shall be final in matters of quality and methods of construction. The sewer, as constructed, must pass the exfiltration test required in § 85-32 before it is to be used. The cost of the sewer extension thus made shall be absorbed by the developers or the property owners, and thereafter the property owners will be subject to a sewer service charge proportional to their use of trunk sewers and treatment plant and their proportion of operational and maintenance costs as outlined in Article X.
Sewer design shall be in accordance with the
following provisions.
A.
Pipe shall be of a type approved by the Town Engineer.
B.
Trench widths.
(1)
Trench widths as measured just above crown of the
pipe shall not exceed the following:
|
Pipe Diameter
(inches)
|
Trench Width
| |
|---|---|---|
|
8
|
3 feet 3 inches
| |
|
10
|
3 feet 6 inches
| |
|
12
|
3 feet 9 inches
|
(2)
If the trench widths are found, during field inspection,
to exceed the limits in the above table, the sewer pipe shall be encased
with a minimum of six inches of concrete.
C.
Pipe shall be firmly and evenly bedded on a minimum
of three inches of No. 1A or No. 1 crushed stone (New York State Department
of Transportation specification).
D.
Pipe thickness and field strength.
(1)
Pipe thickness and field strength shall be calculated
on the following criteria:
|
Safety factor
|
1.5
| |
|
Load factor
|
1.7
| |
|
Weight of soil
|
120 pounds per cubic foot
| |
|
Wheel loading
|
16,000 pounds
|
(2)
Utilizing the above information, design shall then
be made as outlined in Chapter IX of the Water Pollution Control Federation
Manual of Practice No. 9, Design and Construction of Sanitary and
Storm Sewers.
Manholes shall be constructed at all changes
in slope alignment or at intervals not exceeding 400 linear feet.
The manholes shall be constructed with a poured three-thousand-pound-per-square-inch
concrete base, steel-troweled concrete or mortar inverts and precast
four-foot-diameter concrete manhole barrel sections and a tapered
top section. The manhole frame and cover shall be the standard design
of the Town and shall be set with no less than two courses of brick
underneath to allow for later adjustment in elevation.
A.
All sewers shall satisfy requirements of a final exfiltration
test before they will be approved and sewage flow accepted from them
by the Town. This test consists of filling the pipe with water to
provide a head of at least five feet above the top of the pipe or
five feet above groundwater, whichever is higher, at the highest point
of the pipeline under test and then measuring the loss of water from
the line by the amount which must be added to maintain the original
level. In this test, the line must remain filled with water for at
least 24 hours prior to the taking of measurements. Exfiltration shall
be measured by the drop of water level in a standpipe with closed
bottom end or in one of the sewer manholes available for measurement.
B.
When a standpipe and plug arrangement is used in the
upper manhole of a line under test, there must be some positive method
of releasing entrapped air in the sewer prior to taking measurements.
The test length intervals for either type of test shall be as ordered
approved but in no event shall they exceed 100 feet. In the case of
sewers laid on steep grades, the length of line to be tested by exfiltration
at any one time may be limited by the maximum allowable internal pressure
on the pipe and joints at the lower end of the line. The test period,
wherein the measurements are taken, shall not be less than two hours
in either type of test.
C.
The total leakage of any section tested shall not
exceed the rate of 100 gallons per mile of pipe per 24 hours per inch
of nominal pipe diameter. For purposes of determining the maximum
allowable leakage, manholes shall be considered as sections of forty-eight-inch-diameter
pipe, five feet long. The equivalent leakage allowance shall be 4.5
gallons per manhole per 24 hours for forty-eight-inch-diameter manholes.
If leakage exceeds the specified amount, the necessary repairs or
replacements required shall be made to permanently reduce the leakage
to within the specified limit, and the tests shall be repeated until
the leakage requirement is met.
All sewer extensions constructed at the property
owner's, builder's or developer's expense, after final approval and
acceptance by the Town Engineer, shall become the property of the
Town and shall thereafter be maintained by the Town. Said sewer extensions,
after their acceptance by the Town, shall be guaranteed for one year.
The guaranty shall be in a form provided for by the Town. At the sole
discretion of the Town, a completion bond or certified check may be
demanded as part of the guaranty.
[Amended 4-29-1987 by L.L. No. 4-1987]
A.
No builder or developer shall be issued a building
permit for a new dwelling or structure requiring sanitary facilities
within the improvement boundaries unless a suitable and approved method
of waste disposal is proposed. All new developments shall be provided
with an approved system of sanitary sewers.
B.
All new developments and all new construction shall
be equipped with ultra-low-volume toilets with a maximum tank size
or flush capacity of 1.6 gallons of water per flush or less and shower
heads with a maximum flow capacity of 2 1/2 gallons per minute.
[Amended 10-26-1994 by L.L. No. 5-1994]

building and fire code standards.
