Description:
The City uses approximately 84 pressure reducing valve (PRV) stations to manage water pressure in the City’s distribution system. Many of these PRV stations were built in the 1960s and 1970s and are in need of refurbishment. City staff inspected and evaluated all of the Redmond's PRV stations and generated a list of those needing rehabilitation or replacement. These stations no longer meet City standards due to pipe corrosion, age, type of materials used, and environmental conditions. Corrosion is the main cause of degradation, but other issues include vault drainage and safe access.

This project will abandon and replace 10 PRV stations throughout Redmond. The construction will provide for installation of new vaults, valves, piping and restoration of all street, sidewalk and landscape within the limits of construction.
