City of Kennewick (City) staff has identified deficient water mains in the neighborhood around East 4th Avenue and Elm Street. Existing mains vary in size from 1.25 inches, 2 inches, to 4 inches in diameter and are older galvanized water mains. Because of the small diameter lines, there is a lack of fire hydrants and firefighting resiliency along with deficient flows. During recent years, the City has responded to multiple leaks in the area and the City has determined a need to replace the water mains with larger 8 inch diameter mains. The City’s proposed alignment also crosses the Columbia Irrigation District (CID) canal. Additionally, there are over 50 water meters connected to the old undersized water mains. Most are located in difficult to access areas behind residents’ housing. After installation of the new water mains, water service meters will be relocated to the front yards and reconnected to individual homes, the roadway will be patched, and the small diameter water mains will be abandoned.
