A. SPECIFICATIONS. All Building Sewers and Sewer Service lines shall be of PVC schedule 40, ductile iron pipe, or extra strength cast iron soil pipe. Joints shall be made by using a City approved pre-formed compression gasket. Individual service lines shall not be less than 4 inches in diameter and shall be placed at a uniform grade of not less than 1/8 of an inch per foot. Sewer Service lines shall contain no more than two (2) 45 degree bends, clean out shall be at intervals not to exceed 80 feet. Multiple connections of more than one building shall be as approved by the City Engineer as described under Section 14-304.M.
No interconnection of the existing private sewer system shall remain upon connection to the public system. If a Sewer Service connection is such that gravity flow can be had to the public sewer main and a sump pump is presently used, said sump pump shall be disconnected, discontinued and removed from service.
All water service lines shall be PVC AWWA C-900, ductile iron pipe, or Type K copper tubing. Service lines shall have a minimum of 7.5 feet of cover to adequately protect from freezing. Where a service has not previously been provided, all new connections to the watermain shall be performed “under pressure” and a gate valve or curb stop provided at the point of connection or property line.
The service installer should verify the location and elevation of the connection before proceeding with the installation. Any deviation from the plan location which will affect the installing of the service connections, should be brought to the attention of the City immediately. The City will assume no responsibility for extra charges as a result of such misplaced connection unless it is notified before any work is done and has had an inspection made by its representative to confirm the condition and to authorize extra work.
B. DUAL WATER LINES. Subject to applicable plumbing and fire code requirements, the City Building Official and the Public Works Superintendent of the City may require installation of dual and separate water lines for fire suppression and potable water to service a commercial or multifamily building. Factors for consideration include actual or anticipated water usage, occupancy, and impacts on the Waterworks system. Dual waterlines must start at the City watermain and have shutoff valves separate from any other water supply to the structure.
