Stormwater Harvesting Benefits

Stormwater harvesting utilizes a free resource to reduce municipal water supply costs, while complying with regional stormwater management guidelines. In southern climates, a no infiltration system (complete with liner) can be used as the long term storage reservoir, with the water being used for irrigation, washing, or other non-potable applications.

An integrated control system, which include water harvesting information is typically used to operate these harvesting systems. In addition, where the PICP is also serving a stormwater collection system, it is recommended that an active control system be used to monitor weather forecast information and to automatically draw down the water volume to accommodate projected precipitation rates.

How Does a PICP Stormwater Runoff System Store Water?

A Permeable Interlocking Concrete Pavement (PICP) stormwater runoff system stores water by allowing stormwater runoff to infiltrate through porous surfaces into a storage reservoir.

The PermeCapture™ System

In certain applications, combining the benefits of PICP with the high volume detention/retention capabilities of StormCapture® vaults provides rainwater collection solutions for challenging site conditions. Examples of potential applications for PermeCapture™ include: coastal areas or sites with high water tables; poor or limited aggregate availability; poor soils, shallow rock, or excavation challenges; sites requiring access for inspection & maintenance of retention/detention water, or sites where aggregate water storage is not recognized or credited.
