All extensions to the public sanitary sewer system 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 County Health Department and/or New York State Department of Environmental Conservation. Plans and specifications for sewer extensions shall be submitted to and approval obtained from the Engineer, Ulster County Health Department and New York State Department of Environmental Conservation before construction may proceed. The design of sewers must anticipate and allow for flows from all possible future extensions or developments within the immediate natural drainage basin area.
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 § 113-19. The installation of the sewer extension must be subject to full-time inspection by the Engineer, and the expenses for this inspection shall be paid for by the owner, builder or developer. The 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 § 113-21 before it is to be used. The charges to be made for the use of any such sewer extension shall be determined by resolution of the Town Board.
A. 
Sewer design shall be in accordance with the following provisions:
(1) 
Pipe: shall be of a type approved by the Engineer.
(2) 
Trench widths.
(a) 
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
(b) 
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.
(3) 
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).
(4) 
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, as may be amended from time to time.
A. 
When required by the Superintendent, the owner of the property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole, together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times.
B. 
If there is more than one street lateral serving an industrial user, the Superintendent may require the installation of a control manhole on each lateral.
C. 
The Superintendent may require that such monitoring station(s) include equipment for the continuous measurement and recording of wastewater flow rate and for the sampling of the wastewater. Such station(s) shall be accessibly and safely located, and the industrial user shall allow immediate access, without prior notice, to the station by the Superintendent, or his designated representative.
A. 
All sewers shall satisfy requirements of a final infiltration/exfiltration test before they will be approved and sewage flow from them accepted 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 the first 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 standard pipe 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 400 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 of 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 of 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 Engineer, shall become the property of the Town, at no cost to the Town, and shall thereafter be maintained by the Town. Those sewers not installed in public roads shall be installed in permanent utility easements. Easements shall be acceptable to the Town Attorney, approved by the Town Board and recorded in the Ulster County Clerk's office prior to acceptance of the sewer by the Town. Said sewers, after their acceptance by the Town, shall be guaranteed by the property owner, builder or developer against defects in materials or workmanship for 12 months. The guaranty shall be in a form provided for by the Town. At the sole discretion of the Town, a performance completion and maintenance bond or certified check may be required 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 area serviced by public sewers unless a suitable and approved method of waste disposal is proposed. All new developments shall be provided with an approved system of sanitary sewers.
