The only Rainwater Harvesting System supplier you will ever need


Our Combi rainwater harvesting systems are suitable for a wide range of applications and buildings. For more information on our Combi systems, please don’t hesitate to contact us.

How does a Combi system work?

Our unique control system combines the benefits of both a gravity-fed header tank system and the pressurised supply of a boosted water system. This is by far our best-selling and most specified product!

As with our other systems, rainwater follows the same journey until it reaches the Combi control unit. The rainwater is stored in either a 400L or 620L internal buffer tank, before being distributed at pressure by either fixed or variable speed, twin booster pumps. As with all Stormsaver systems, there is an automatic, mains water top up to provide a continuous water supply, complying with the guidelines set out by WRAS.

The unit is pre-plumbed and assembled with any BMS connections, automatic backwashing filtration or controls that you may have specified and is fully tested before leaving our manufacturing facility. This will save you time and labour on site, and minimises the likelihood of mistakes being made during the installation.

More on our rainwater harvesting systems

All of the Stormsaver rainwater harvesting systems will make the most economic use of the local rainfall with predicted water consumption.

It is recommended that you speak to our expert staff to help you choose the correct type of system for your application and that you choose low water consuming products to complement the system, furthering a reduction in overall consumption.

All Stormsaver systems come with a 12 month warranty from date of commissioning.

How much does it Cost?

The exact costing of each Combi Rainwater Harvesting System varies depending on your specific needs. However, it’s also worth noting that the Stormsaver rainwater harvesting system is an accredited part of the Enhanced Capital Allowance (ECA) scheme.
