Statewide General Waste Discharge Requirements (WDRs) for Wineries

The State Water Board has developed General WDRs for winery process water (Winery Order) for wineries and other similar facilities (collectively referred as wineries) with activities related to producing wine or grape juice that generate winery waste and discharge it to land for reuse or disposal. The Winery Order is applicable statewide and is intended to streamline and improve permitting consistency.

The State Water Board will continue to engage the public and stakeholders as part of the Winery Order implementation process and this website will be updated with related information as it becomes available.
