Industry Leaders In Rainwater & Stormwater Management

This rainwater harvesting system begins with a WFF300 Vortex Pre‑filter, which removes debris and particulates from rooftop runoff before the water enters the storage system. Once pre‑filtered, the collected rainwater is conveyed to a 25,000‑gallon fiberglass‑reinforced plastic (FRP) underground storage tank, where it is held for treatment and distribution. Submersible pumps located within the tank deliver the stored rainwater to a 50 GPM treatment skid engineered specifically for treating roof‑collected water. After treatment, the water is transferred to a dedicated day tank that maintains a ready supply of clean, treated water. From this tank, a duplex booster pump system repressurizes the treated water and distributes it to the building’s water closets and urinal fixtures, ensuring reliable and consistent service.

In addition to supporting water‑efficient operation, this system was implemented as part of the project’s strategy to achieve LEED water conservation and rainwater management credits. To ensure the rainwater system met LEED objectives and integrated effectively with the mechanical and plumbing design, RMS collaborated closely with the project’s engineering team during system development. This collaboration aligns with LEED’s emphasis on integrative design, which encourages coordination among system designers to optimize water efficiency strategies and maximize achievable credits. By working directly with the engineers, RMS ensured that system sizing, treatment performance, and distribution capabilities supported the project’s LEED goals while delivering a robust, maintainable, and code‑compliant rainwater harvesting solution.
