There shall be no physical connection between sewers <br />and water supply systems. Sewers shall be set back from water supply <br />systems and piping as required for building sewers (See Chapter 150.014B <br />herein). ~ere Jt is not possible to obtain proper separation dis- <br />tances, the sewer connections shall be watertight and pressure <br />tested as outlined in Chapter 150.014B. <br /> <br /> 7. Pump stations shall be watertight and have manholes <br />flush with or above finished grade for cleaning and maintenance. <br /> <br /> 8. Manhole covers shall be so constructed as to prevent <br />una,thorJzed entry. <br /> <br /> 9. Pumps and pump stations shall be sized to handle peak <br />flows and an alarm system shall be provided for all pumping stations <br />to warn of pump failure, overflow, or other malfunction. <br /> <br />MAIMf~WANCE <br /> <br />A contract for the'maintenance of all.common drainfields, sewage <br />tanks, pumps, pump stations, sewers, and all individual tanks con- <br />nected to a common drainfield shall be maintained by the city and <br />all persons using the system. Such contracts shall be made jointly <br />and shall continue for the life of the system. <br /> <br />MEfFERING <br /> <br />Sewage flow shall be monitored continuously, recorded monthly, and <br />reported annually to the council. Metering can be accomplished by <br />installation of a water meter to measure the flow to all pumping <br />fixtures except the outside sil]cocks or, if a sewage pump is used, <br />installation of a pump cycle counter on the sewage pump. <br /> <br />S~d. 3 SEEPAGE PITS <br /> <br />Seepage pits may be used for disposal of sewage effluent in the Urban <br />Service Area when such use is indicated by favorable conditions of <br />soil, ground water level, or topography, and where such use does not <br />reduce the safety of surrounding ground water supplies. The pit exca- <br />vation shall terminate at least'four (4) feet above the highest known <br />or calculated ground water table. <br /> <br />k~en two (2) or more seepage pits are used, a distribution box con- <br />structed in accordance with ~150.014D shall be used if the inlet <br />inverts of the seepage pits have no more than one (1) foot differ- <br />ence in elevation. If the difference in elevation between the in- <br />let inverts is greater than one (1) foot, the seepage pits shall <br />be connected' in series. <br /> <br />The location of seepage p~ts, in addition to the general provisions <br />under Chapter ]50.014F, shall be not less than the stated minimum <br />distances from the following: <br /> <br /> <br />
