§ 27-498. Requirements for sanitary sewer.

(a)

Central sanitary sewer required. Every principal use and every lot within a subdivision shall have central sanitary sewer.

(b)

Approval, connection to municipal system. No subdivision lot shall be sold, nor buildings connected to sanitary sewer until the sanitary sewer has been inspected, approved, accepted and connected to the municipal system. The system shall not exceed a rate of two thousand five hundred (2,500) gallons per mile per day of infiltration or exfiltration.

(c)

Size requirement. Sanitary sewers shall be eight (8) inches minimum unless a larger size is stipulated by the city sewerage plan. Sewers, lift stations and force mains, including maximum and minimum grades, capacities and velocities, shall be designed to accommodate a peak flow of twice the average daily flow stipulated by the sewerage guide of the state board of health. In residential developments population shall be based on the rate of two (2) persons per bedroom, but no less than ten (10) persons per acre.

(d)

Pumping facilities. Where the sewerage cannot be connected to the municipal system by gravity flow, a lift station with connecting force main must be constructed by the developer. If the city requires the developer to construct a lift station with a greater capacity than that required by the development, the city will reimburse the developer for a pro rata share of the cost of the lift station based on the ratio of area developed to the area ultimately served by the station. Where a lift station has been previously constructed, the developer shall reimburse the city, at the same ratio, for the cost of the same before connection.

(e)

Private treatment facilities. Use of existing on-site wastewater treatment systems may remain in service until such time as central sewer is available within five hundred (500) feet of the property boundary, service is requested by the residents, or septic tank failures become known and identified. Such connection, when necessary, shall be made at the expense of the owner.
