Customized Calcium Hypochlorite System Steps Up To The ChallengeSource: Arch Chemicals, Inc., a Lonza company
Rainbow Water District has 2,400 service connections serving approximately 6,400 customers in the unincorporated portion of Springfield, OR. The district, approximately 100 miles south of Portland, is served by excellent quality groundwater from 10 wells at four well fields near the McKenzie River.
The groundwater is naturally filtered by local sands and gravels as it is pumped from the ground and a small amount of chlorine is added as a disinfectant. Each well field has its own chlorination station and transmission main, which allows for sufficient chlorine contact time before reaching the district’s water distribution system.
