Notice: Based on the current guidance to minimize the spread of COVID-19, the Non-Discharge Branch has adjusted operations to protect the health and safety of the staff and public. Many employees are working remotely. To accommodate these changes, we ask that all requests/inquiries be made by email. Please refer to the staff directory below. We appreciate your patience during this challenging time.

The Non-Discharge Branch is responsible for the permitting and compliance of residual and wastewater effluent land application facilities. The branch is also responsible for permitting facilities for the beneficial use of reclaimed water for the purpose of conserving the state's potable water, surface water, and groundwater resources.
