(A) All extensions shall be constructed to meet city and state requirements as to size and locations. All extensions greater than 280 feet shall be designed by a registered professional engineer or as required by state statute.
(B) The minimum pipe size shall be eight inches, except a six-inch pipe may be used on the last 250 feet of a sewer which cannot possibly be extended due to topographic limitations.
(C) Sewers shall be constructed of PVC pipe generally, with cast iron being required under waterways. Other pipe materials may be approved by the city on a case by case basis. All sewers shall be bedded in a well graded, free draining granular material free from large amounts of silts and clay. Bedding material shall extend from one-half diameter of pipe below to one-half diameter of pipe above installed sewer line.
(D) Manholes shall be provided at every change of alignment and grade and shall not exceed 500 feet in spacing. Manholes shall be constructed with precast sections, with the completed manhole being equal in quality to those in the original sewer system.
