According to the U.S. Environmental Protection Agency (EPA), about 90 percent of surface pollutants are carried by the first 1-1/2 inch of rainfall.
Storm water drains don’t typically channel this polluted runoff to treatment facilities, but instead convey it directly into local water bodies. Polluted runoff, if not diverted, ends up in our waterways along with water that is heated as it flows over paved surfaces and into the watershed. The concern being that temperature change in a stream or lake can harm aquatic plants and wildlife.
The use of pervious concrete (Percoa Slabs)is a widely accepted as an effective material to capture, filter and disperse storm water runoff and is among the Best Management Practices (“BMPs”) recommended by the EPA as well as by other agencies
Percoa’s proprietary, patented products can be used for new construction or to retro-fit existing concrete or asphalt surfaces such as storm water runoff basins, parking lots, driveways, walkways, patios, and a myriad of other surface applications where water runoff is a concern. Percoa combats the harmful effects of pollution entering the water supply, and helps reduce temperature changes.
