| Résumé : |
Billions of gallons of untreated stormwater pollute our lakes, rivers and oceans every year. Conventional concrete and asphalt pavements concentrate these pollutants at the storm drains. Whether it is through a combined sanitary sewer system or a local detention pond, treatment is expensive. In most areas, the stormwater remains untreated, allowing the pollutants to flow directly into our waterways.
The next time you walk across a street or through a parking lot, take a closer look around. You’ll probably see some solid waste like paper, food, bird droppings or animal feces, or possibly some fertilizer from a neighboring lawn. More than likely, there will be some stains from cars that have leaked oil, brake fluid, transmission fluid or antifreeze. What do you think will happen to these materials during the next rain?
In all probability, they will end up in a storm drain that is discharged directly into a local lake, river or ocean. Recent studies have found that urban rainwater and snowmelt rivals (and in some cases exceeds) sewage plants and large factories as a source of damaging pollutants.1 Storm water washing over impervious surfaces can pick up toxic chemicals, disease-causing organisms, dirt and trash. Conventional hard-surface pavements concentrate these pollutants at the storm drains, thereby creating what the U.S. Environmental Protection Agency (EPA) considers a point source emission of pollutants. In most cases, stormwater is not treated because it is too expensive or impractical.
A Filterpave® porous pavement system can reduce or eliminate stormwater runoff from many areas and provides some unique benefits compared to impervious pavement or even other types of porous pavement. It is appropriate for parking areas, driveways, walkways, patios, golf cart paths and other light- to medium-duty traffic areas. |
