Wastewater Branch
Mission Statement
The Wastewater Branch administers the statewide engineering functions relating to water pollution control, municipal and private wastewater treatment works, individual wastewater systems and the Clean Water State Revolving fund. The Wastewater Branch’s mission is to protect public health and the environment.
Please Note:
Our jurisdiction does not extend to properties serviced by sewer. To see if you are serviced by sewer, check your water bill for a sewer charge or check if you receive a sewer bill. Any complaints or questions related to wastewater issues on these properties should be directed to the relevant county department or private sewer system provider.
