The Norfolk water system consists of two water treatment plants, supplied by two well fields. The two fields have a total of 12 wells averaging 81 feet in depth. The combined pumping capacity is 10,000 gallons per minute, and the storage capacity is 4,800,000 gallons, with an historic peak for daily demand at 9,910,000 gallons. Both water treatment plants use aeration and filtration to remove iron and manganese.
Polymer is also part of the treatment used at the east water treatment plant.
Both treatment plants provide disinfections prior to distribution to the community. The combined capacity of these plants is 11.5 million gallons per day. The static pressure of the water at the treatment plants varies from 80 to 100 psi and residual pressure varies from 40 to 90 psi. Currently there are two pressure zones in the city s distribution system. Zone 1 generally serves all land below the elevation of 1,600 feet, with Zone 2 serving all land above the elevation of 1,600 feet.
