Shoulder drain provides a constructed pathway for water to migrate away from highway and airport taxiway pavements. Through a combination of perforated pipe and clean aggregate, the harmful effects of water intrusion are decreased while pavement longevity is increased. Carolina Environmental Contracting has installed shoulder drains on highway rehabilitation projects as well as on new road construction.
Carolina Environmental Contracting (CEC) recently completed the design and construction of a BMP (Best Management Practices) site, built as a stormwater management solution to accommodate new construction at Moses Cone Hospital in Greensboro, NC.
The additional building footprint and nonporous paving area required the installation of a 3,000 square-foot pond that forces stormwater to filter through vegetation, a specialty soil mix, sand, and stone before entering the stormwater piping system.
Construction site BMPs utilize different methods and materials on construction sites before and during the construction phase of the project to control stormwater discharge or pollutants commonly found in stormwater. The newly installed bioretention pond will serve as a permanent BMP that will continue to filter water after construction completion.
