A. 
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.
B. 
Plans and specifications for sewer extensions shall be submitted to and approval obtained from the engineer and the New York State Department of Health before construction may proceed.
C. 
The design of sewers must anticipate and allow for flows from all possible future extensions or developments within the immediate drainage area.
A. 
When a property is outside the boundaries of the Sewer Improvement Area but adjoins said boundary on at least one side, the owner of said property may, by contract approved by the Town Board, become a contract user of the Sewer Improvement Area, provided that the proposed user's sewer discharge is within 400 feet of the Sewer Improvement Area boundary line.
B. 
The contract user shall be assessed a property tax and sewer use fees calculated in the same manner as a property within the Sewer Improvement Area as defined elsewhere in this chapter. In addition, the contract user shall pay a proportional share of a special district construction assessment, if applicable.
[Amended 7-24-2000 by L.L. No. 2-2000]
C. 
The contract user shall pay legal fees incurred by the Sewer Improvement Area for contract preparation.
D. 
The contract user is subject to all rules and regulations as defined in this chapter.
A. 
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.
B. 
Under this arrangement, the property owner shall pay for and install the building sewer from the property line to the building in accordance with the requirements of Article IV.
[Amended 7-24-2000 by L.L. No. 2-2000]
C. 
Thereafter, each property owner served by the extended public sewers will be charged at the full service charge rate as outlined in Article X.
D. 
Property owners may, in accordance with applicable law, propose sewer extensions within a Sewer Improvement Area 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.
[Amended 7-24-2000 by L.L. No. 2-2000]
A. 
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 the section.
B. 
The property owner must pay for the entire installation, including all expenses incidental thereto.
[Amended 7-24-2000 by L.L. No. 2-2000]
C. 
Each building sewer must be installed and inspected as required by Article IV, and the inspection fees shall be paid.
D. 
Design of sewers shall be as specified in § 118-32.
E. 
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 § 118-34 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 plants and their proportion of operational and maintenance costs as outlined in Article X.
A. 
Sewer design shall be in accordance with the following provisions:
(1) 
Pipe shall be of a type approved by the Town Engineer. Trench widths as measured just above the 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. 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). Pipe thickness and field strength shall be calculated on the following criteria:
(a) 
Safety factor: 1.5.
(b) 
Load factor: 1.7.
(c) 
Weight of soil: 120 pounds per cubic foot.
(d) 
Wheel loading: 16,000 pounds.
B. 
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.
A. 
Manholes shall be constructed at all changes in slope alignment or at intervals not exceeding 400 linear feet.
B. 
The manholes shall be constructed with a poured concrete base of 3,000 pounds per square inch, steel-troweled concrete or mortar inverts and precast four-foot-diameter concrete manhole barrel sections and a tapered top section.
C. 
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 pipe line 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.
[Amended 7-24-2000 by L.L. No. 2-2000]
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 and/or maintenance bond or certified check may be demanded as part of the guaranty.
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.
