(A) All sanitary sewer facilities shall be installed in compliance with the regulations of the State Department of Public Health and the State Environmental Protection Agency, and must be approved by the Village Engineer.
(B) Whenever the public sanitary sewerage system is reasonably accessible, that is, when the distance from the property to be subdivided to the nearest public sewer with available capacity does not exceed 200 feet, the developer shall extend said system throughout the subdivision and shall provide each lot with a connection thereto.
(C) In areas where the public sanitary sewerage system is not reasonably accessible, but where plans for the installation of said system have been approved by the State Environmental Protection Agency, the developer shall provide sanitary sewers in accordance with such plans and temporarily cap them.
(D) Except as provided in divisions (A) or (B) above, whenever connection to the public sewerage system is not reasonably accessible and plans for such a system have not been approved by the IEPA, the developer shall install a private central sewerage system approved by the Village Engineer.
(E) Whenever the provisions of divisions (A), (B) or (C) above are applicable, the developer shall comply with the following regulations.
(1) The developer shall attempt to locate every sanitary sewer main within the area between the pavement edge and the right-of-way line of the street.
(2) Where a sewer main crosses a proposed street, the developer shall back fill with compacted limestone screenings, sand or other approved granular material.
(3) The developer shall provide a six-inch service connection for each residential lot, the lateral of which, shall be extended at least ten feet into the lot, as measured from the lot line, and extended vertically to a minimum of three feet above the finished grade level. The exposed end shall be sealed with a six-inch cap glued in place. The transition from the horizontal to the vertical shall be made by the use of a six-inch 90-degree “long sweep” or a series of two 45-degree elbows.
(4) Where a lateral crosses a proposed street, the trench shall be backfilled with limestone screenings, sand or other approved granular material.
(5) All sections of all sanitary sewer mains, laterals and the like shall be air-tested. All mains shall also be mandrel tested, lamped and televised. All testing shall be done by an independent testing agency approved by the village.
(a) When air testing, all sections of sanitary sewer mains, laterals and the like, eight inches or less in diameter, shall be pressurized to at least four P.S.I. above the surrounding ground water pressure, and must not drop more than one P.S.I. after a minimum duration of five minutes. Sewer mains over eight inches in diameter shall be tested as required by the Village Engineer. A copy of the testing results, showing a minimum of the initial test pressure, the final test pressure and the duration of the test shall be submitted to the village prior to final acceptance of the development. The test results shall be certified by the testing agency.
(b) An approved testing company shall televise all sanitary sewer mains. A digital format denoting the manhole number, distance between laterals and manholes shall be depicted on the digital format. The manhole number on the digital format shall be the manhole number shown on the plans for the development and the corresponding village designated manhole number. A report in eight and one- half by 11-inch format shall be submitted detailing the results. The digital format and the report shall identify all observed construction deficiencies, pipe material flaws and the like. The report and a copy of the digital format shall be submitted to the village.
(c) All sanitary sewers mains shall be lamped by an approved, independent agency to ensure consistent slope and alignment prior to acceptance. A report shall be submitted to the village.
(d) All manholes shall be vacuum tested.
1. The vacuum should reach ten inches water column and hold the pressure for the time specified in the following chart.
Time (in Sec.) | |||
Manhole Depth (feet) | 48-Inch Diameter | 60-Inch Diameter | 72-Inch Diameter |
Time (in Sec.) | |||
Manhole Depth (feet) | 48-Inch Diameter | 60-Inch Diameter | 72-Inch Diameter |
8 | 20 | 26 | 33 |
10 | 25 | 33 | 41 |
12 | 30 | 39 | 49 |
14 | 35 | 46 | 57 |
16 | 40 | 52 | 65 |
13 | 45 | 59 | 73 |
20 | 50 | 65 | 81 |
22 | 55 | 72 | 89 |
24 | 59 | 78 | 97 |
26 | 64 | 85 | 105 |
28 | 69 | 91 | 113 |
30 | 74 | 98 | 121 |
2. If the vacuum drops more than one inch within the test time, the manhole is considered unacceptable. A copy of the testing results, showing a minimum of the initial test pressure, the final test pressure and the duration of the test shall be submitted to the village prior to final acceptance of the development. The test results shall be certified by the testing agency.
(e) The developer shall provide a sanitary sewer as-built to the village. The as-built shall show the location, flowline and depth of all manholes and the location of all laterals. All elevations shall be based upon the existing sewer system datum of the village. The developer shall submit all as-built data both on hard copy and in an Autocad format as approved by the village.
