Customer Service: Investigating and mitigating spills and other unpermitted discharges helps protect public health and safety. Permitting and monitoring industrial and commercial discharges allows all users to equitably share the sewer service and treatment resources that MSD provides. All these activities aid in the protection and enhancement of a cleaner water environment in our streams, and so, our quality of life.

Regulatory Compliance: The Pretreatment Program is required under State Permit and State (401 KAR 5:055 (9)) and Federal (40 CFR 403) Regulations to inspect and monitor the 121 Significant Industrial Users in Jefferson County. IWD goes beyond the minimal regulatory requirements and monitors all industrial and commercial establishments that have in the past or could in the future adversely affect MSD’s service to public health or the environment, or that use a disproportionate share of the cost of operating MSD’s treatment system. The Quality Charge Program assures that these customers pay their fair share of the cost of treating their wastewater.
