Unclogging Storm Drains




The 2100 Vactor Combination Unit has a water jet that loosens the debris in drains and removes it. DPU has two Combination Units and two units that are not combinations. It requires at least two people to operate the Vactor. They go to drains recommended for service by citizen and maintenance division requests.

Staff position the Vactor tubing in a storm drain after cleaning away any overgrowth blocking the drain or manhole cover.




Debris fills the drain. Stormwater cannot flow through, and that causes flooding in the street. The debris also contains bacteria that is carried to the James River.



A DPU employee places a marker on the cleaned drain to remind people "No Dumping. Drains to Waterway."
