Glasgow Completes Work On Storm Water Projects

All of the major construction for Glasgow’s recent storm water projects has been completed, Town Manager Eric Pollitt announced at the Oct. 8 Town Council meeting.

Usually, soil absorbs storm water. But in developed areas with impervious surfaces, like pavement, the runoff doesn’t get absorbed and instead picks up pollutants: trash, oils, and dirt, for example, which can harm the bodies of water that it flows into. To protect bodies of water, communities can use storm water controls.

Pollitt explained that Glasgow has some untreated runoff as a result of development, upstream forestry and mining activities; that means that a significant sediment supply has been impairing local stream and storm water infrastructure.

To help solve these problems and flooding problems, the town constructed a wetland and a bioretention facility.

A wetland is an ecosystem flooded by water, similar to a marsh. Constructed wetlands, like natural wetlands, can remove pollutants from the water and help slow down storm water. This wetland basin will manage it water coming down from Sallings Mountain and keep it from coming down during storms. The wetland is located roughly a quarter of mile up Sallings Mountain on the side of the mountain

The bioretention facility, which will store and treat storm water, is located outside the Town Hall. Water enters the bioretention facilities through a depression or basin (in this case, a ditch, which is outside Town Hall) before it gets absorbed into the underlying bioretention soil. Any excess storm water flows into an adjacent drainage system. Glasgow’s storm water will rush through the ditch with biomaterial which helps filter out pollutants; then it will go to underground storage systems and come back out into the drainage system back to the upper James River and the Chesapeake Bay.

Pollitt said that storm water, particularly in the commercial district, has long been a thorn in the side of economic development in Glasgow.

The work for the project was provided by Harbor Dredge and Dock, and it was funded with a $200,000 grant from the National Fish and Wildlife Foundation.
