In Wilmington, stormwater runoff is channeled through a complex system of storm drains, pipes, ditches, ponds, culverts, creeks and wetlands which flow straight into our waterways. Stormwater Services field crews perform maintenance of the storm drainage system within the public right-of-way or in accepted easements.

Stormwater Services maintains the stormwater drainage system including:

  • 18,508 catch basins and manholes
  • 312 miles of pipe/culverts 
  • 218 miles of open drainage (ditches, channels)
  • 46 acres of retention ponds (Randall Pond, Silver Stream Pond, etc)
  • 131 acres of stormwater Best Management Practices (Kerr Avenue Wetland, Park Avenue Bioretention, Wade Wetland, Dock Street Rain Gardens, etc)

For fiscal year 18/19:

  • 315 loads of street sweeping debris collected
  • 7,949 miles of streets swept
  • 362 bi-annual inspections of private retention ponds
  • 33 miles of ditches cleaned manually
