How is Water Treated?

Water is pumped from Lake Georgetown, approximately nine miles, through two pipelines, 24 and 30 inches in diameter, to the treatment plant.

1. As the water enters the plant, alum and polymer, which are coagulants, and fluoride are added to the water.
2. In the flocculation basin, the chemicals are mixed with the water.
3. The sedimentation basin allows the particulate matter in the water to settle to the bottom.  Clearer water moves on to the next step.  Solids, dirt and debris from the lake water are a byproduct of the treatment process.
4. After sedimentation, the water is filtered through anthracite coal and is disinfected with chlorine.
5. Ammonia is added prior to storage so that chlorine byproducts will not form as the water is distributed to the customer.
