What is the purpose of the National Pretreatment Program?

The purpose of the National Pretreatment Program is to ensure that effluent discharged into municipal wastewater treatment systems does not contain toxic pollutants that could interfere with the treatment process or contaminate the receiving waters. This program specifically targets industrial dischargers and aims to limit the introduction of hazardous substances into the sewer systems. By implementing pretreatment standards and requirements, the program protects both the treatment facilities and the environment by minimizing the risk of harmful substances entering the waterways.

The focus of the National Pretreatment Program is crucial for the overall effectiveness of wastewater treatment, as untreated toxic pollutants can severely disrupt biological processes in treatment plants and lead to compliance issues with environmental regulations. It also addresses public health concerns associated with the potential release of toxic substances into the community.
