Industrial Pretreatment

Clermont County’s wastewater treatment plants are designed to handle domestic wastewater from typical households, not the industrial wastes from a factory or business. Wastewater discharged from an industry may contain pollutants that could interfere with the operation of the county’s treatment plants. Clermont County Water Resource Department (CCWRD) began the industrial pretreatment program to help control the wastewater flow coming into the treatment facilities.

Certain customers, often known as Significant Industrial Users (SIU), must be permitted under the industrial pretreatment program. SIUs must also control the quality of their discharge by installing appropriate systems that will “pretreat” their wastewater prior to discharging into the sewer system. CCWRD regulates this program through wastewater sampling and on-site inspections of commercial and industrial facilities.
