RainCycle Commercial Rainwater Harvesting

Setting the standard for rainwater harvesting

As the industry leader in developing water sustainability solutions, Watts sets the standard for rainwater harvesting. Our commercial rainwater harvesting systems are used in North America to efficiently capture, store, treat, and deliver non-potable water for a variety of end uses including irrigation, restrooms, laundry, and more. Using only the highest quality components on the market, we create modular systems that can be customized to meet nearly any location and project need.

How RainCycle™ Works

Rainwater harvesting offers a sustainable approach to water management. It not only helps commercial and industrial buildings conserve water by reducing the demand on municipal water sources, it can reduce energy consumption and provide economic savings.

Learn how the RainCycle™ Rainwater Harvesting system easily collects rooftop rainwater and then pre-filters, stores, processes and distributes it as non-potable water for such end uses as restrooms, irrigation, and cooling tower water makeup.

Rainwater Harvesting Systems

RainCycle RCS-7000 series packages are stand-alone building scale systems for collecting, storing, and treating roof-collected rainwater for non-potable end uses. These PLC controlled systems make it easy to monitor performance from a central location.

Standard Features

Filtration rated for up to 80 GPM
304 stainless steel headers, branch piping and frame
2-stage cartridge-type, low maintenance filtration in a non-metallic filter body
Fully controlled, auto-dim UV
Filtration differential pressure monitoring
Tank level monitoring
UL 508A control panel with PLC and 7 in. color touch screen
All alarms with audio/visual display, time-delayed proof of condition, auto-reset and control logging
All components are touch safe regardless of voltage class
RS485, Modbus/BACNet/LonWorks/OPC-UA (native) communications

How they work

Rainwater flowing from a clean roof surface is routed to an inlet pre-filter, then to a cistern
Water is pumped from the cistern through the filtration skid to a buffer tank for temporary storage
Filtered/treated water is distributed from the storage tank to the end use systems
If the water level is too low in the cistern, a bypass valve or motorized makeup valve enables domestic water to flow through to the buffer tank

Exclusive RainCycle Features:

A proprietary control algorithm allows the booster pumps to function without a hydropneumatic tank
Field adjustable pipe break detection technology is included in the controller to shutdown pumps during unusually high flow conditions which are indicative of a pipe break
Factory changes require rolling passwords. This allows only authorized users to make factory setting changes
