Roanoke County is mandated by Federal law, through its Municipal Separate Storm Sewer System (MS4) Permit, to establish an illicit discharge program. An illicit (i.e., illegal) discharge is any substance that is deposited or allowed to flow into the County’s municipal separate storm sewer system that is NOT entirely composed of stormwater, except those specifically exempted on the list below.
The County’s Department of Community Development is responsible for operating and enforcing the Illicit Discharge Program.
Unlike wastewater from sinks, toilets, and showers, which flows via an underground pipe system to a treatment facility for cleaning/purification before it is discharged into waterways, stormwater is untreated and goes directly into local creeks, streams, and the Roanoke River. Thus, nothing should be poured or deposited into the storm drainage system, which includes the street, curb and gutter, drainage inlets, pipes, ditches, and other channels.
If you see anything other than stormwater going onto street surfaces or into the storm drains within the County, such as leaves, grass clippings, motor oil, etc., please report it immediately by submitting the below form, online. You may also contact the County’s Stormwater Program Manager at (540) 772-2065.
The following non-stormwater discharges are allowable, unless they have been identified by the County Administrator or Virginia Water Control Board as significant contributors of pollutants:
