    Industrial Wastewater Control

    Industrial Wastewater Control (IWC) works with businesses to ensure that harmful substances are kept out of the sewer system. View information about the program and permit applications.

    Permitting & Water Management

    The Permitting, Water Quality and Data Management sections work collaboratively with one another as they are an important link between the monitoring requirements, efforts and the informed data analysis for assessing & reporting the quality of the water. Permitting is responsible for implementing all federal and state wastewater laws and regulations as Water Quality provides the monitoring efforts to meet the requirements.
