Source Control and Industrial Pretreatment

As a result of a federal government (Environmental Protection Agency) mandate, Water Environment Services (WES) implemented an industrial pretreatment program in 1986. The program currently provides permits to 27 industrial businesses.

Direct services provided by the program include industrial permitting, facility inspections, sampling, laboratory analysis and enforcement. Indirect services include: development of local limits, updating rules and regulations, load investigations, responding to regulatory authorities and conducting industrial surveys.

Staff inspects the industrial pretreatment processes of businesses to eliminate illegal discharge of harmful chemicals into the sewage treatment process and collects wastewater samples to ensure industrial compliance with federal and state environmental regulations and local sewer ordinances.
