The process of transmitting and distributing drinking water to our customers begins as the clean water leaves the filtration gallery of the Water Purification Plant.

From the Water Purification Plant, the water flows to two underground "clearwell" storage tanks on the grounds of the lakeside plant complex. These tanks, which have a combined capacity of 6 million gallons, hold the water for approximately four hours before it is pumped out to the city and surrounding communities via four primary, 16- to 36-inch diameter transmission mains and four high-service pumps. This transmission system has a combined 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, 39.7 mgd, occurred on July 23, 1999.

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.
