Since 1981, communities across the country have been able to regulate industrial discharges into wastewater treatment plants in order to enhance the ability of those plants to protect human health and the environment. Johnson County Wastewater's Industrial Pretreatment Program extensively regulates industrial wastewater discharges so that toxic materials do not interfere with wastewater treatment systems or pass through to receiving streams. The program issues permits, inspects, and monitors industries to control discharges to the sanitary sewers. This program also investigates instances of illegal and harmful wastewater discharges.
Wastewater Discharge Standards
A sanitary sewer is a system of underground pipes designed to carry domestic sewage from bathrooms, sinks, kitchens, and other plumbing components to a wastewater treatment plant where it undergoes various treatment processes before it is ultimately discharged into the environment. The sanitary sewer system should never be used for disposal of anything other than domestic wastewater; without first obtaining the proper, written, authorized permit issued by Johnson County Wastewater. Disposal of chemicals or hazardous substances such as: oils, grease, gasoline, paint, anti-freeze, etc. to the sanitary sewer system may cause damage to our environment and create potential safety hazards for county workers and residents alike.
