Stormwater ponds slow runooff and allow for sediment and other pollutants to precipitate out of the water column. Over time this sediment accumulates on the bottom of the pond and will eventually impede the function, health, and esthetics of the pond. Dredging restores the pond by physically removing this accumulated sediment.
Virginia Waters and Wetlands provides turnkey dredging services. Below are photos of a dredge we completed on a 1 acre pond in the Northern Virginia Area. Over 1,100 cubic yards of accumulated sediment was removed from this pond.
Note the dark sediment layer as opposed to the light red clay basin. The dark layer is the sediment accumulation that is being excavated from the pond.
