Storm Water Charge

Credits and Fee Adjustments Appeals

The City of Wilmington’s integrated storm water management program addresses the storm water needs of the City while protecting its water resources. The major goal of this program is to reduce the amount of pollutants discharged into the surface waters including rivers and creeks. These pollutant discharges occur as a consequence of storm water run-off, combined sewer overflows and wastewater treatment plant discharges.

The City is engaged in several management activities to mitigate the impact of these pollutant loads on rivers, including pre- and post-construction storm water management, watershed planning and protection, waste water treatment plant improvements, reduction of volume and frequency of combined sewer overflows, and surface water quality enhancement efforts through the promotion of storm water quality and quantity management utilizing best management practices.
