  1. 1. Pervious Surface Solutions For Water Management
  2. 2. The importance of pervious ground solutions:
  3. 3. Food for thought… Global Water Supply As Impervious Surfaces Increase  Water Quality Declines 
  4. 4. More problems associated with impervious surfaces: Water Quality Issues • Sediment is carried from surface wear and erosion. • Nutrients are accumulated from surface flows, especially lawns, field crops, and pet waste. • Temperature increases due to warm pavements. • “Industrial” pollution – fuel, oils, greases, insecticides, heavy metals, other toxins are also picked up.
  5. 5. Effects of Combined Sewer Overflow • CSO (Combined Sewer Overflow) occurs when a heavy rain event causes a massive increase in storm water flow into the sewage treatment facility and leads to a combined flow that exceeds the facility’s total maximum daily load. This results in the discharge of raw, untreated sewage into the river (or bay or ocean) and subsequent contamination. We’ve all seen the beach, boating and fishing closures that follow and other subtle effects linger on.

  8. 8. Drainage Dynamics of Flow in the Chamber
  9. 9. A Typical EPIC Profile The EPIC profile stays moist as water wicks upward by capillary action from the chambers The EPIC system can utilize 40-80% less water for irrigation while removing nutrients Pans Or Geomembrane

  13. 13. What is Porous Pave? • Porous Pave is an environmentally friendly surfacing material made from recycled tires. • Porous Pave XL - Uses a Non-Toxic, Urethane Hard Binder ▫ 50% rubber chips, 50% stone aggregate • Porous Pave XLS - Uses a Non-Toxic, Urethane Soft Binder ▫ All rubber chips
  14. 14.  One of Porous Paves Biggest Features is its Highly Porous Structure  Allows Large Volumes of Water to Drain Through It Quickly Porous Pave Key Features Minimizes amount of water directed to storm drains , basins, and other drainage areas.
  15. 15. Porous Pave Key Features Slip Resistant  High Rubber Content Ensures Good Traction Even When Wet  Lessens the Chance of Slip and Fall Accidents  Textured Surface is NOT Slippery Compared to Concrete
  16. 16. Pathways / Trailways  Excellent Erosion Control and Water Diffusion Capabilities  Can be Poured on Slopes Up To 30% Grade  Low Impact Installation
  17. 17. Parking Lots  Improves Pervious/Impervious Ratio of Site  Can be Snow Plowed Without Damage Provided Shoes Are Used  Highly Resistant to Gas and Oil, and Most Common Chemicals Found on Parking Lots
  18. 18. Aggregate Base Preparation SPECIAL NOTE  Base needs to be much thicker where high water holding capacity is needed.
  19. 19. Storm Water Management
  20. 20. Defining Porous Pavement • The EPA Identifies a porous pavement as a special type of pavement that allows rain and snowmelt to pass trough it. • It reduces the runoff from a site and surrounding area’s. • In addition, porous pavement filters some pollutants from the runoff if maintained.
