Dover’s stormwater management program was seeing an increased volume of grit-laden street waste from hundreds of miles of streets, drainage systems, and 3,200 catch basins.
Under the Clean Water Act, the EPA requires that all Municipal Separate Stormwater Sewer Systems (MS4s) obtain a NPDES permit. Stormwater collection systems employ the often-seen curbs, gutters, ditches and pipes, but also utilize unseen catch basins that drop out and store trash, grit and other debris before ultimately discharging the stormwater to a local waterway (creeks, streams, river and lakes).
The city wanted to explore alternative means for handling and disposing of this waste to reduce current costs of handling but also to be better stewards of the environment.
The city uses the wastewater treatment facility to centralize and collect the deposited grit, trash and other debris which collects in the storm drainage systems. At the heart of the catch basin treatment system is a Huber RoSF5 grit waste treatment system.
