Wastewater Treatment

Where Wastewater Comes From

Each residence served produces an average of 375 gallons of wastewater (also known as sewage) every day, which amounts to more than 30 million gallons of wastewater processed daily for our 120,000 residential customers. Business and industrial users produce more than five million gallons of wastewater, bringing the total wastewater handled each day to more than 35 million gallons. Our current wastewater processing capacity is 51 million gallons daily.

Wastewater is moved from its originating source, whether residential, business or industrial, to two strategically located processing facilities through a network of 1,825 miles of sewer mains and 45 wastewater pump stations.
