watersBCWS’s wastewater system serves about 100,000 people in Butler County. We operate two regional wastewater treatment plants: LeSourdsville and Upper Mill Creek; and four satellite treatment plants: Wade Mill, Alamo Heights, New Miami and Queen Acres. The six plants treat about 20 million gallons of wastewater every day and have a combined permitted discharge flow of 33 million gallons per day.

What is wastewater?
Wastewater is simply used water. It includes substances such as human waste, food scraps, oils, soaps and chemicals. In homes, it comes from sinks, showers, bathtubs, toilets, washing machines and dishwashers. In addition, businesses and industries contribute their share of wastewater that must be treated.

How is wastewater treated?
Wastewater is treated with the use of biological, chemical and physical processes. Wastewater treatment removes solids and biological pollutants, treating the water to acceptable levels before returning clean water, called effluent, back into the environment.
