Water Treatment Process

Have you ever wondered how tap water reaches your faucet? Or, what measures Dalton Utilities takes to ensure clean water? This diagram gives you a glimpse of the process. Starting at the water source (e.g. the Conasauga River), here are the steps involved in getting safe, clean water to your home.

Steps in the Water Treatment Process

  1. Screens at the water intake prevent fish and large debris from entering treatment plant.
  2. Pumps push raw water to the treatment plant.
  3. A flash mix is added to cause particles remaining in the water to coagulate or clump together.
  4. In the flocculation chamber, iron and manganese are oxidized to improve taste and odor.
  5. Water enters the settling basin to allow any existing solids to settle to the bottom. Clumped particles sink to the bottom of the basin. The sludge is sent to a storage lagoon.
  6. Chlorine is added to disinfect the water before filtration.
  7. Filters remove fine particles and other impurities from the water.
  8. In the disinfection process, Chlorine is added to destroy bacteria, lime to control corrosion, fluoride to brighten smiles.
  9. Pumps send the water to the distribution system.
  10. Clean water is now available as needed in your home.

Water Distribution Process

  1. High service Pumps send finished water from the Treatment Plant to Transmission Water Mains.
  2. The Transmission Water Mains carry the water to customers’ service lines and to Water Storage Tanks which are located at high elevations throughout the service territory.
  3. Water flows by gravity from the Water Tanks to area Businesses and Houses.
  4. Booster Pump Stations are also added for pumping water up to customers located at higher elevations.
