This document is the case study for the New River Valley Plant case study, Dublin, VA, (METRIC). A project to handle 11 million liters of storm water discussed.

In order to help clients meet the Virginia Department of Environmental Quality’s regulations for stormwater, various ADS products were used on a project that could handle nearly 11 million liters (2.5 million gallons) of water.

Four beds of StormTech MC-4500 detention chambers were installed to handle the stormwater storage. The chambers also provided stormwater quality as StormTech Isolator Row was utilized for removal of total suspended solids.

For pretreatment of the stormwater, each chamber unit was equipped with a Barracuda hydrodynamic separator. A BaySeparator water quality unit was placed upstream for addition stormwater treatment. Nyloplast curb inlets captured the stormwater and N-12 water tight pipe was used to convey stormwater. Nyloplast and N-12 have water tight connections, which were used because of seepage concerns.

The installation was done in July 2021 using 1,700 MC-4500 StormTech Chambers 2,743 m (9,000’) of N-12 HDPE pipe, 30 ADS Nyloplast Curb Inlets, 3 ADS Barracuda Stormwater Separator, 1 BaySeparator Stormwater Treatment System.

Photographs of the project are included.
