All extensions to the sanitary sewer system shall be properly designed in accordance with and in strict conformance with all requirements of the New York State Department of Environmental Conservation. Plans and specifications for sewer extensions shall be submitted to, and approval obtained from, the Village Engineer and the 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 drainage area. Nothing herein shall supersede the requirements of the Village of Chittenango Subdivision Regulations and/or Zoning Ordinance.[1]

Editor's Note: See Ch. 125, Subdivision of Land, and Ch. 148, Zoning.
Sewer extensions, including individual building sewers from public sewer to the property line, may be constructed by the Village if, in the opinion of the Village 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. Property owners may propose sewer extensions within the Village in accordance with the Village Law and as it may be amended. The cost of such extensions may be assessed to the benefited property owners in any manner determined by the Village Board in accordance with the Village Law.
A. 
If the Village does not elect to construct a sewer extension, the property owner, builder or developer (hereinafter called the "applicant") may construct the necessary sewer extension upon application and approval by the Engineer in accordance with the requirements of § 115-36. All expenses related to the cost of design and construction shall be borne by the applicant. Each building sewer must be installed and inspected as previously required. Design of sewers shall be as specified in § 115-39. The installation of the sewer extension is subject to inspection and approval by the Engineer.
B. 
The Engineer's decisions shall be final in matters of quality and methods of construction. The sewer, as constructed, must pass the exfiltration test required in § 115-40 before it is to be used.
C. 
The cost of sewer extension thus made shall be absorbed by the developers or the property owners, including all building sewers.
A. 
Sewer design shall be in accordance with the following provisions. Pipe material shall be either polyvinyl chloride (PVC) conforming to ASTM D3034, Class SDR35, or conforming to ASTM F789; extra-strength vitrified clay conforming to ASTM Specification C-200; or reinforced concrete conforming to ASTM Specification C-76. No standard strength clay pipe or nonreinforced concrete pipe shall be used. Minimum internal pipe diameter shall be eight inches. Joints for each kind of pipe shall be designed and manufactured such that O-ring gaskets of the snap-in type are employed. Gaskets shall be continuous, solid natural or synthetic rubber and shall provide a positive compression seal in the assembled joint such that the requirements of § 115-40 are met. Joint preparation and assembly shall be in accordance with the manufacturer's recommendations. Wye branch fittings shall be installed for connection to building sewers in accordance with Article IV. Trench widths as measured just above the crown of the pipe shall not exceed the following:

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. Pipe shall be firmly and evenly bedded on a minimum of six inches of No. 1A or No. 1 or No. 2 crushed stone (NYSDOT specifications). Pipe thickness and field strength shall be calculated on the following criteria:
(1) 
Safety factor: 1.5.
(2) 
Load factor: 1.5.
(3) 
Weight of soil: 120 pounds per cubic feet.
(4) 
Wheel loading: 16,000 pounds.
C. 
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, or any revision thereof.
D. 
Manholes shall be constructed at all changes in slope or 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 six inches thick, steel-troweled concrete or mortar bench walls and inverts and precast four-foot-diameter concrete manhole barrel sections with concentric tapered top section, as specified by ASTM C-478. The manhole frame and cover shall be the standard design of the Village and shall be set with no less than two courses of brick underneath to allow for later adjustment in elevation. All joints shall be sealed against infiltration. Manholes shall be constructed with manhole steps.
A. 
All sewers shall satisfy requirements of a final exfiltration test before they will be approved and sewage flow accepted from them by the Village. This test consists of filling the pipe with water to provide a head of at least five feet above the top of the pipe in the upstream manhole 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 convenient measuring.
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 or approved, but in no event shall they exceed 1,000 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. Low-pressure air tests may be used upon the Engineer's approval in lieu of exfiltration tests.
In addition to the requirements as set forth in the Subdivision Regulations of the Village of Chittenango for the acceptance of subdivision improvements,[1] the following conditions shall also apply for the acceptance of sanitary sewers:
A. 
Upon completion of the work, the applicant shall prepare and submit to the Engineer one reproducible copy of as-built drawings showing final rim and invert elevations, final station of all manholes, physical ties to manholes, location and length to the property line of all wyes and any other necessary information for the proper maintenance and operation of the system.
B. 
The applicant shall tender to the Village Attorney the originals of all deeds and easements, along with any necessary subordination or other agreements so as to convey an unencumbered interest in the proposed sewer right-of-way areas, if any, to the Village of Chittenango, properly signed and acknowledged in recordable form and a signed real property transfer gains tax affidavit (Form TP-584 or acceptable substitute). The dedicator shall also provide, at dedicator's expense, either a policy of title insurance naming the Village of Chittenango or an attorney's certificate of title certified to the Village of Chittenango covering the property interests conveyed, current to the date of recording of the deed and/or easement. Dedicator shall pay all recording fees.
C. 
The prospective dedicator shall provide a maintenance bond for the value of the completed sewer construction in the amount fixed by resolution of the Village Board. This bond shall be conditioned for the faithful performance by the dedicator of any repairs needed to correct or replace any and all damage to said sewer for a period of one year from the date of acceptance.
