A service pipe shall be defined as a private service, tapped off a public water main, feeding a single lot or single entity/tenant.
Either copper or ductile iron pipe, of any standard diameter, may be used at the option of the consumer. High Density Polyethylene pipe (HDPE) may be used for service sizes of 2” or less in area not bounded by the groundwater control areas noted herein. Copper service pipe shall be at least one-eighth inch larger in diameter than the tap through which it is supplied. All piping associated with fire protection shall conform to the testing and flushing requirements of the adopted version of the National Fire Protection Association (NFPA). All other piping shall be tested and flushed per the adopted version of the adopted Plumbing Code and/or the discretion of the Building Department. Any piping found to be transferring electric current should be brought to the attention of the City Building Department at the time of discovery.
In all cases, service pipes larger than two inches in diameter, which are laid between the water main in the street and the backflow device, shall be of pressure class 350 ductile iron, either mechanical joint or slip joint pipe. This shall be built and laid to withstand a pressure of 200 psi and must conform to City of Grand Island Division VI Specifications and Standards, the Plumbing Code adopted by the City of Grand Island, or current AWWA standards; whichever is most restrictive.
All service pipes shall be laid under the surface of the ground with no less than five feet of earth cover, and in all cases shall be so protected as to prevent rupture by freezing unless otherwise authorized by the Utilities Department.
All new service pipe, two inches or smaller in diameter, laid between the water main and the curb stop at the property line shall be built of continuous construction without joints, unions, or splices; however, two inch pipe may be installed with soldered joints or compression fittings. All piping shall meet the following specifications:
Copper Pipe:
Copper pipe shall be Type K, cold drawn to size and of the proper bending temper and shall be made from phosphorized copper completely deoxidized and have a purity of at least ninety-nine and nine-tenths percent copper. Copper pipe shall have the following dimensions:

High Density Polyethylene Pipe (HDPE):
The underground HDPE water service lines shall meet the following requirements:
1) NSF approved for drinking water
2) Minimum of 200 psi rated for pressure
3) ASTM D 2737 & AWWA C901
4) All connections will conform to the standard copper tubing sizes noted herein.
