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.
