What is the Industrial Pretreatment Program (IPP)?
The City’s Environmental Protection Division (EPD) has an industrial pretreatment program regulated by the U.S. Environmental Protection Agency (EPA). The objective of this program is to protect water quality by setting effluent limits for industries or non-domestic wastewater discharges to the city’s sewer collection system.
What is an Industrial Pretreatment Permit?
An Industrial Pretreatment Permit is a permit that sets effluent limits from an industry discharging to the City of Manchester’s sewer collection system.
