What happens to rainwater?

Two combined sewer overflow facilities capture and store 1.5 million gallons of wastewater during rain events which is later pumped to the treatment plants for proper treatment. During wet weather, the Altoona Water Authority utilizes these facilities to capture the “first flush” from the combined sewer areas in order to remove organic solids and debris which in past years went directly to the stream. The solids removed from the wastewater are further treated through a state-of-the-art process that yields a nutrient rich fertilizer that enables local farmers to reduce reliance on chemical fertilizers.
