The ACSA strives to provide our customers with high quality, reliable and safe drinking water at a reasonable rate. Our raw water is supplied from local rivers and reservoirs and is pumped to one of five water treatment plants, owned and operated by the Rivanna Water and Sewer Authority. As the illustration to the right shows, once the raw water arrives to the treatment plant, it is treated with a coagulant, the pH is adjusted and the water is mixed to help particulates stick together. The flocculation basins is where the water flow is slowed to allow the particulates to stick to other particulates. When the water flows to the sedimentation basins, the particulates sink to the bottom and are removed. The water then flows through several large filters, removing the remaining microscopic particiles and microorganisms. Thereafter, chlorine is added to disinfect the water. Final treatment includes further adjustment of the pH before it reaches your faucets.
All water sampling is conducted by our wholesaler, Rivanna Water and Sewer Authority. Results of annual water sampling can be found in your Annual Consumer Confidence Report (Water Quality Report) by clicking here.
