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.

Regulating Point-Source Pollution

Delaware’s National Pollutant Discharge Elimination System (NPDES) program regulates point sources that discharge pollutants into the waters of Delaware.

Land Treatment

The section permits land treatment of wastes (wastewater treatment by-products and non-hazardous residuals from solid waste treatment) in limited agricultural applications or as landfill.

Wastewater Treatment Facilities

The section issues permits to construct facilities that will store, collect, convey or treat sewerage and other wastewaters and ensure that facilities are designed to manage wastes properly.
