Commercial Rainwater Harvesting Systems
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.
The need to maintain an aesthetic surface is another reason to utilize this type of system. PermeCapture™ vaults are H-20 rated, and include HydraPorts to allow water from the PICP system to drain into the storage chambers. When used as a retention system, treatment benefits of PICP rainwater harvesting technology can be incorporated into the PermeCapture™ system.
Benefits of Rainwater Harvesting
Rainwater harvesting offers significant cost savings by reducing reliance on municipal water for irrigation and washing. It minimizes stormwater runoff, erosion, and promotes groundwater recharge. The system enhances water quality, supports regulatory compliance, and improves drought resilience, providing a sustainable and cost-effective water management solution.
Cost Savings
Harvested rainwater can substantially reduce water bills, especially for large commercial installations and extensive landscaping projects. Property owners can significantly lower utility expenses by offsetting potable water usage with rainwater. Over time, these savings can add up, making rainwater harvesting a financially smart investment.
Meet Stormwater Regulations
Commercial rainwater harvesting helps meet stormwater regulations by reducing runoff, which minimizes flooding and erosion risks. Properties comply with local stormwater management policies by capturing and storing rainwater onsite, mitigating environmental impact and avoiding potential fines. This approach also contributes to sustainable site development goals and regulatory adherence.
Backup Water Storage
Commercial rainwater harvesting provides reliable backup water storage, ensuring a steady supply during droughts or municipal water disruptions. This system supports non-potable applications like irrigation and cooling, maintaining operations despite water shortages. It enhances resilience and operational continuity, making it an invaluable asset for commercial properties.
