Our programs for operating and maintaining public streets, roads and highways minimize the discharge of pollutants. Yearly maintenance is performed statewide on Delaware's stormwater system. Periodic checks of these drains and pipes are not the only upkeep performed.

Street sweeping is one tool used to decrease litter and debris that can clog storm drains and be carried into a nearby lake or stream. Another innovative tool is the creation of roadside wetlands for the trapping of sediment and debris; this way runoff cannot enter nearby waterways via the stormwater system.

Aside from these efforts, the entire community is responsible for helping to maintain our waterways. Stormwater is not treated by water treatment facilities (as wastewater is) before flowing into our ecosystem, which is why it is important that everyone is involved.

Though yearly maintenance is performed on these drains, they can become clogged with trash and silt. Report clogged stormwater drains by calling DelDOT at 800-652-5600.
