DID YOU KNOW?

Rainfall in the U.S.:

According to the U.S. E.P.A. Ninety percent of rain events in the U.S. never exceed ½ inch of rain per hour. A permeable pavement would capture this...

DID YOU KNOW?

Stormwater Runoff:

According to the U.S. EPA, 40 percent of the U.S. rivers, lakes and estuaries are pollution-impaired and almost half of this problem is due to stormwater runoff. A permeable pavement would help to solve this...

DID YOU KNOW?

Stormwater Pollution:

The three largest sources of stormwater pollution are: agriculture, urban runoff and sediment from construction sites. A permeable paving surface would fix urban runoff...

DID YOU KNOW?

Soil and Silt:

When stormwater runoff contains soil and silt, the temperature increases and changes occur in the aquatic habitat and food supply. A permeable paving surface would lower the temperature...

DID YOU KNOW?

Untreated Stormwater:

Untreated stormwater runoff may contain decaying leaves and other organic materials that increase bacteria and mosquito production and decrease oxygen essential for fish life. A permeable paving surface may solve this...

DID YOU KNOW?

Where Storm Drains Lead:

The U.S. EPA estimates that approximately 70 percent of all storm drains lead directly to rivers, lakes and estuaries. This contaminated stormwater is never treated. A permeable paving surface would treat this stormwater runoff.

Stormwater Pollution:

Stormwater pollution is the largest cause of pollution in the U.S. A permeable paving surface would solve this...

Paved Parking vs Meadow:

According to one site study conducted by the U.S. EPA, the total volume of stormwater runoff from a 1-inch of rain event was 16 times GREATER for a 1 acre paved parking lot than that generated from a 1-acre meadow.

How it Works



PaveDrain Design Assistance

PaveDrain Design Objective

The stone reservoir immediately beneath the PaveDrain System is ¾" clean angular stone (#57 Stone) with no fines. The depth of this first stone reservoir beneath the PaveDrain System ranges from 6"-10" based on the soil conditions, anticipated loading and storm water volumes. Additional stormwater storage can be achieved by adding an additional layer of larger diameter (2"-3") stone to the required depth.

A geogrid or woven monofilament geotextile layer is STRONGLY recommended below the bottom layer of stone to maintain a clean stone reservoir and enhance structural stability. Please contact PaveDrain, LLC for geosynthetic recommendations.

Void space for stone varies from 30% on ¾" clean stone and up to 40% for 2-3" clean stone.

PaveDrain, LLC will provide a mat layout of the project and recommended mat sizes to optimize job efficiency and improve cost. A standard mat size measures 8' x 18.0' long.



PaveDrain® permeable paving supported by HydroCAD

Click for detailsHydroCAD-10 provides direct support for the PaveDrain system of permeable articulating concrete block mats. This allows the storage and infiltration capabilities of PaveDrain installations to be easily modeled with HydroCAD.

The PaveDrain can be modeled with HydroCAD-10, which provides an interactive chamber wizard for easy layout, pricing, and modeling of modular storage systems.

INFILTRATION REPORT

American Excelsior Company's ErosionLab® was contracted by ECS Solutions, LLC to help better understand the infiltration capabilities of the PaveDrain® porous paver technology.

The outdoor testing for the study was conducted during August 2010 at ErosionLab. The PaveDrain blocks were installed over two plots that contained different underlying materials. The plots were exposed to increasing simulated rainfall events with one hour durations until runoff was measured from the plot.

POLLUTANT REMOVAL

EPA Pollutant Removal Chart VIEW COMPARISON CHART Porous Pavement BMP's score at or NEAR the top in virtually every major category.

Infiltration systems can be considered 100 percent effective at removing pollutants in the fraction of water that is infiltrated, since the pollutants found in this volume are not discharged directly to surface waters. Quantifying the removal efficiency of infiltration systems, therefore can best be determined by calculating the percent of the average annual runoff volume that is infiltrated, and assuming 100 percent removal of pollutants found in that runoff volume.

Cost Analysis

Prices for the PaveDrain System will vary per region across the United States. A conservative cost for a standard gray PaveDrain block is around $6.00-$7.00 per square foot. This price may or may NOT include delivery depending on the plant location and the cost of fuel.

Installation is typically around $2.00-$3.00/square foot. The aggregate bedding layers typically costs around $2-3/square foot. Overall costs have been around $9.50-$11/square foot depending on the size of the project. If developers do NOT have to purchase additional land and or incur massive excavation costs in order to meet stormwater regulations, they are more inclined to lean in the direction of PaveDrain System as their stormwater management system of choice.
