Surface Water Discharges Section

The Surface Water Discharges Section issues permits for industrial and municipal wastewater treatment systems, including stormwater treatment, which discharge into Delaware’s surface waters. It also regulates the management of wastewater sludge. The Section licenses wastewater treatment operators and provides technical assistance and training to help wastewater treatment facilities avoid problems.
