The “District” is co-owner of the Chelan Fish Hatchery with the WA Department of Fish and Wildlife “WDFW” who is contracted to operate the entire hatchery located off the US97 and Columbia River. The District elected to increase water supply to improve hatchery rearing conditions. Two crews worked, each focusing on different scopes in different locations at the property. The old water main, constructed with cement asbestos pipe for removal, from the well field to the hatchery and old degassing towers had limited capacity. The work subsequently involved de-watering, creating a new transmission main and degassing facility with greater capacity including five new water segments with a total of 2,500 LF of 28” HDPE (fusion welded), 300 LF of 36” steel casing pipe for a temporary bypass (involving ramming, boring beneath highway), 7,350 LF 2” PVC conduit, 8” ductile iron storm drainage improvements, valves, manifolds, 8” – 30” diameter gravity drain yard pipe, 8”-28” diameter pressurized yard piping for degassing towers along with other valves, fittings, manholes, earthwork, electrical blowers, flow meters and instrumentation, new concrete raceways, site and surface restoration.
Project Owner: City of Leavenworth
This project involved replacing 60+ years-old 10” water main with approximately 3,800 LF of 16” water main. 49 out-dated water services were also replaced with new service pipe, valves, meter boxes along with installing new fire hydrants and subsequently repaving the entire road with HMA surfacing.
