CWLP's two clearwell storage structures are located on the grounds of the lakeside plant complex just east-northeast of the Water Purification Plant. (See Building a New Clearwell and Pumping Stations
to learn about CWLP's newest clearwell.) These concrete structures, which have a combined capacity of 10 million gallons, hold the water for an average of about eight hours before it is pumped out to the city and surrounding communities via three primary 24-, 30- and 36-inch diameter transmission mains
and six high-service pumps located in the utility's new high-service pump station. This pump station has a capacity of 65 million gallons per day (mgd). On a typical day, however, only about a third of this capacity is called upon. On average, the utility treats more than 22 mgd. The maximum amount ever treated in one day, 40.28 mgd, occurred on July 25, 2012.
From the transmission mains, the water is further conveyed through six- to twelve-inch distribution mains to CWLP's Springfield customers. Water that is not immediately needed is temporarily stored in three above-ground storage tanks
