The clear choice in storm drain maintenance
Preventing pollution and flooding
What is the NPDES Stormwater Program?
The U.S. Environmental Protection Agency’s National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from municipal separate storm sewer systems (MS4s), construction activities, and industrial activities. Most stormwater discharges are considered point sources, and operators of these sources may be required to receive an NPDES permit before they can discharge. This permitting mechanism is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters such as streams, rivers, lakes or coastal waters. All six New England states are authorized to implement the NPDES Stormwater Program and administer their own stormwater permitting programs.
Under the Clean Water Act, cities and towns are required to develop plans to minimize runoff and monitor pollution sources. Compliance with these regulations will include certification of plans, photo documentation and reporting of maintenance on storm drain systems and catch basins.
Waste buildup breeds problems
The waste that builds up in storm drains is high in solids, has high concentrations of heavy metals, and can be contaminated with petroleum hydrocarbons. In addition, pools of standing water that gather in blocked storm drains are breeding grounds for mosquitoes and other disease-carrying insects. This is of particular concern with the spread of the dangerous West Nile virus in the New England region.
Catch basins should be cleaned once or twice each year, and more frequently in industrial use areas. Frequent clean-out helps to retain the volume in the catch basin sump for treatment of wastewater flows.
