Pretreatment is the reduction, the elimination, or the alteration of pollutants in wastewater to a less harmful state prior to discharging the wastewater to the sanitary sewer system.
The Pretreatment Program is an EPA mandated and City funded program to regulate all industrial discharges into the municipal wastewater collection system, reducing the amount of pollutants released into the environment from the treatment plant.
A Pretreatment Operator is assigned to follow strict EPA and DEQ guidelines by submitting data, collecting samples, surveying users, inspecting and keeping permits updated. The goal of the Pretreatment Program is:
Prevent the introduction of pollutants into the municipality wastewater system that will interfere with the operation of the system or contaminate the resulting sludge.
Prevent the introduction of pollutants into the municipal wastewater system that will pass through the system and into the Rogue River.
Improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges.
Protect the health and safety of the general public and City of Grants Pass Water Workers.
The pretreatment program inspects and surveys industrial users of the City’s collection system and Wastewater Treatment Plant. It issues Wastewater Discharge Permits, collects samples, and enforces the City’s Sewer Use Ordinance 8.50.
