Any particles remaining in the water after the softening process are filtered through layers of anthracite coal and sand. Chlorine may be added before or after filtration to prevent bacterial growth. Fluoride is added to meet Environmental Protection Agency recommendations and helps improve dental health. Distribution Softened, filtered water is pumped from the water treatment plant to reservoirs at the West Ash Pump Station and the South Pump Station. The water is then pumped throughout the city to consumers.
Water is stored in three water towers that provide capacity for peak flows and fire fighting.
The pressure is increased at the Northeast Booster Station, because of the higher elevation in that area.
