How Can YOU Prevent Stormwater Pollution?
By the WNY Stormwater Coalition
What is stormwater?
Stormwater is water from rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas, bare soil, and sloped lawns. As it flows, stormwater runoff collects and transports animal waste, litter, salt, pesticides, fertilizers, oil & grease, soil and other potential pollutants.
What’s the problem?
Rain and snowmelt wash pollutants from streets, construction sites, and land into storm sewers and ditches. Eventually, these empty the polluted stormwater directly into streams and rivers with no treatment. This is known as stormwater pollution.
Polluted stormwater degrades our lakes, rivers, wetlands and other waterways. Nutrients such as phosphorus and nitrogen can cause the overgrowth of algae resulting in oxygen depletion in waterways. Toxic substances from motor vehicles and careless application of pesticides and fertilizers threaten water quality and can kill fish and other aquatic life. Bacteria from animal wastes and improper connections to storm sewer systems can make lakes and waterways unsafe for wading, swimming and fish consumption. Eroded soil is a pollutant as well. It clouds the waterway and interferes with the habitat of fish and plant life.

We always are asked about freeze – thaw in our product.
Because of the void structure and the way we manufacture Percoa Slabs they work well in places where temps can drop to below 0. Just last week we hit -12 with the wind-chill putting us at -30.
This picture shows Percoa Slabs on the right and failing poured in place pervious concrete on the left.
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.
