The U.S. Congress created the national EPA-mandated Pretreatment program in 1972.
This program protects the nation’s wastewater treatment plants and waterways from discharges of toxic and other pollutants.
Many industries must pretreat wastewater before sending it to the sewer. This protects the wastewater treatment process, water quality, and facilities.
What Does Metro’s IPP Do?
The EPA approved Metro Water Recovery’s own Industrial Pretreatment Program (IPP) on August 25, 1986. Metro’s IPP administers pretreatment regulations to make sure the wastewater generated by industries in our service area is treated properly. Pretreatment also helps to protect Metro employees and the public.
Metro’s IPP team members work with businesses who discharge to our connectors. This includes several different types of activities:
Metro’s IPP also guides the Hauled Waste Program and the Dental Amalgam Control Program. Click the buttons below to learn more, or scroll down for more information about Metro’s IPP.
What Industries are Regulated by Metro’s IPP?
All businesses — including industrial, commercial and governmental establishments — that discharge anything other than normal sanitary wastewater are subject to the requirements of the IPP. Under its IPP, Metro does not have authority to regulate any domestic discharges from residences.
