2-Fall 2025 Appendix A - Specifications.xlsx

This file contains specifications for Parks Backflow, Master Valve, and Hydrometer Installation projects for West Valley City, Utah. The scope of work encompasses installation of backflow prevention devices, master valves, hydro meters, and related components across 13 park locations within the city. The specifications detail equipment requirements including cage and concrete base installations, drain quick couplers with ball valves, isolation valves, master valves with wired hydro meters and flow sensors, and shielded wiring connections to controllers. Specific installations vary by location, with depths ranging from 1 inch to 8 feet 6 inches and configurations designated as either Double Check (DC) backflow preventers in vaults or Reduced Pressure (RP) backflow preventers in vaults. The Request for Proposal deadline is December 22, 2025, at 10:00 p.m. local time, with submissions required through the Utah Bonfire Hub portal. No public opening will be held, and results will be posted on the City Website.

Key technical requirements include use of Leemco restraint fittings on mainlines 2 inches and larger to prevent thrust blocks, installation of quick couplers after the master valve, and attachment of all cages to concrete bases at ground level. All work must be inspected prior to burying under pressurized system conditions, potentially scheduled for spring due to weather considerations. Shielded wiring for hydro meters, flow sensors, and master valves must be run and installed to the controller with testing to verify proper operation. The contractor is responsible for repairs of any damage caused during project execution. Inquiries regarding the RFP should be directed to Dustin Bushnell at dustin.bushnell@wvc-ut.gov. West Valley City reserves the right to reject any or all proposals and waive any defects.
