Domestic rainwater harvesting systems can save up to 50% of water consumption within the average home. Water can be used for toilet flushing, washing clothes, garden watering and car washing.

The RainSava domestic rainwater harvesting range offers a number of system options. Direct fed systems are the most popular due to their simplicity; in this range we offer the “Classic”, “Eco Pro” and “Maxima” systems. All use our WISY® Vortex filter, the finest rainwater filter on the market, and our unique high-flow mains water top-up unit.. The Eco Pro system offers the user lower power consumption, built in system diagnostics, and easier system monitoring from the advanced control unit.

For those seeking a lower cost option, then look at our RainSava Classic that uses a simple automatic pump with inbuilt controller.

The Maxima is our top of the range unit ideal for larger domestic properties as well as small commercial applications.

Completing the range we also have our Gravity system utilising a compact and reliable header tank.

Highly reliable, simple, and safe!
