Industrial sewage may contain
significant quantities of toxic pollutants and other substances. These pollutants
may interfere with the wastewater treatment system. Industries are required
to provide treatment of process water to remove any such pollutants.
City in a Pretreatment Program supervises industries. The Program
regulates and monitors the discharge from industries that enter the sewer
system. There are six industries permitted by the City:
Moen, Chatsworth, BSH Dishwasher, BSH Range,
Maola Milk and Ice Cream, and Coastal Regional Solids Waste Management.
