Benefits of Permeable Pavers

  Groundwater is a source of drinking water for many people. It also nourishes deep-rooted plants and trees. Replenished by rain and melting snow, groundwater has become an endangered resource, partly because of the impermeable materials used in new developments in and around cities and towns. Roofs, roadways and runways, parking lots, driveways, sidewalks, patios, and tennis courts prevent surface water from seeping into the ground.

  These impervious surfaces often divert water into storm sewers and then into streams. The rush of water may result in costly and sometimes life-threatening floods. Surface runoff also carries toxic pollutants, such as chemicals and oil from paved roadways and parking lots, into rivers, lakes, and reservoirs, where it pollutes drinking water supplies and harms wildlife.


  Another problem caused by so much paving is the buildup of heat in and around cities and towns. Asphalt and concrete absorb sunlight and convert it to heat. The buildup of extra heat around cities and towns is known as the “heat island effect”.


  Next time you build a patio, walkway, parking space, or driveway, you can address these problems by installing permeable materials, some of which allow grass to grow in them. Many attractive options will permit water to drain into the ground. Some even reduce heat accumulation around buildings.
