How do treatment plants protect our water?
Wastewater treatment plants: * Remove solids, everything from rags and plastics to sand and smaller particles found in wastewater; * Reduce organic matter and pollutants--naturally occurring helpful bacteria and other microorganisms consume organic matter in wastewater and are then separated from the water; and, * Restore oxygen--the treatment process ensures that the water put back into our rivers or lakes has enough oxygen to support life.
Where does wastewater come from? * Homes--human and household wastes from toilets, sinks, baths, dishwashers, garbage grinders, clothes washers and drains. * Industry, Schools, and Business--chemical and other wastes from factories, food-service operations, school activities, hospitals, shopping centers, etc. * Storm Water Infiltration and Inflow from Runoff and Groundwater--water that enters the sanitary sewer system during a storm, as well as groundwater that enters through cracks in sewers. The City of Columbia has one set of sewers for wastewater from homes and businesses (sanitary sewers) and a separate system for storm water runoff.
On the average, each person in the U.S. contributes 50-100 gallons of wastewater every day. If you include industrial and commercial water uses, the per person usage of water is as high as 150 gallons per day.
How does our wastewater treatment plant work?
The 16 million gallons per day (average) entering the facility is conveyed by over 635 miles of interceptor sewers, varying in size from 8 inches to 72 inches in diameter. The Sanitary Sewer Maintenance Section is responsible for the maintenance and repair of all public sewer mains and manholes.
The type of wastewater treatment used in the Columbia Regional Wastewater Treatment Plant is called the complete-mix activated sludge
