You may have seen articles in the newspaper or been involved in discussion groups on the subject of sewer overflows that occur in Wilmington, Delaware when it rains. Like many older industrial cities, the City of Wilmington has a combined sewer system. This means that both our sewage and storm water share the same pipes as they flow to the Wilmington Wastewater Treatment Facility and eventually into the Delaware River. This website will help you understand the reasons for these overflows, and their impacts, from an historical, financial and regional perspective.
