Rainsava Eco-Pro


Our flagship direct-feed rainwater harvesting system, designed for reliable everyday use throughout the home and garden.


Eco-Pro combines WISY filtration, a high-quality stainless-steel submersible pump and intelligent control to automatically supply toilets, washing machines and garden outlets. 

Automatic mains top-up maintains continuity of supply when stored rainwater runs low, while the robust, proven components are designed for dependable long-term use.


 How the system works

Rainsava Eco-Pro is a direct-feed system, so harvested rainwater is pumped straight from the underground tank to the points of use, without the need for a separate header tank.

The system is designed around simple, serviceable components. The WISY vortex filter is positioned for easy access and removes debris before water reaches the tank, while the pump controller monitors demand and operates the pump only when water is required.

A multi-stage stainless-steel submersible pump provides steady pressure for everyday use, with built-in protection helping to safeguard the pump if conditions are unsuitable. The tank also incorporates a calmed inlet and managed overflow to help preserve water quality and keep the system working effectively over the long term.

Eco-Pro can be specified to suit different property sizes, roof areas and water demands, making it a flexible option for both new-build and retrofit installations.
