Discharge Permits and Fees

Permission is required for any discharge of industrial wastewater into the City of Winston-Salem’s wastewater collection system. Several different permits are issued based on the nature of the business, the volume and characteristics of wastewater to be discharged. Our program is also involved in the approval of discharges of hauled septage waste at the city’s approved receiving station. The process for obtaining a discharge permit varies for different types of users.

The different types of users are:
