2025 Backflow Testing

Effective April 1, 2004, the City adopted Resolution No. 4783 which established a monthly fee to be charged to single-family residential customers for providing annual testing and maintenance of their backflow prevention assemblies.  This service is to be provided by a qualified contractor (Contractor) and administered by the City Public Works Department (City).

The contractor will provide annual testing and reporting services for approximately 4,650 privately owned backflow assemblies located on premises of single-family residential customers.  Additional assemblies are expected to be added into the contract each month, including new and existing residential assemblies.

A detailed listing of backflow assemblies will be provided to the contractor, including assembly address, general location, make, model, serial number, and size.  Any missing information is the testing contractor’s responsibility to document.  Testing will begin as soon as possible. There are approximately 850 reduced pressure principal backflow assemblies (RPBAs), 3,750 double check valve assemblies (DCVAs) and 30 pressure vacuum breaker assemblies (PVBAs) currently in the system.   Additional assemblies may be added into the contract each month.

Backflow assemblies are located on private property, typically for landscape sprinkler systems and fire suppression systems, or where properties have secondary sources of water such as wells, GPID, or additional hazards identified by the City of Grants Pass.

The contractor is expected to supply all labor, transportation, equipment, and tools necessary to complete the scope of services included herein.  This includes digging out boxes and removing debris.  Properties are to be left in satisfactory condition for the customer. This means it is in the same or better than when the contractor arrived. Proper care especially is to be paid to leave freeze protection in good working order.

Confined space entry is not required.
