Pretreatment Program

Healthy water in our rivers and Narragansett Bay involves more than just the collection and treatment of wastewater. It requires the monitoring and regulating of toxins released into the sewer system.

Because wastewater treatment facilities are not designed to remove metals and other toxic chemicals from the wastewater, the US Environmental Protection Agency (US EPA) requires the NBC to have a pretreatment program that controls the release of these substances into the sewer system. To accomplish this, commercial and industrial users throughout the NBC district are required to obtain a permit so that the NBC can monitor the varied pollutants that are released into the sewer system and ensure compliance with state and Federal requirements.
