How It Works

Stormsaver offer Commercial Rainwater Harvesting for businesses of all sizes, there are a number of options on offer for businesses. But remember that all systems are manufactured to your specific requirements so can be tailored to suit.

How the rainwater harvesting system worksThe four main business rainwater harvesting solutions are:

  • Non Pressurised – gravity fed system 
  • Pressurised system 
  • Combi System (our most popular solution by far)
  • High Level Collection system which can be installed in your roof area.

 

 

 

  

Rainwater is channelled from the roof of the most suitable business building into the storage tank passing an integrated filter to remove large debris, leaves etc. Water then enters the tank via an inlet calmer preventing disturbance to fine sediment on the base of the tank. Tanks can be positioned underground or above ground and can be manufactured as a single piece or sectional unit.

Excess rainwater flows out of an overflow which has a one-way valve and rodent protection to meet BS8515. The system is designed to skim surface particles bi-annually keeping water quality high.

Inside the tank are sensors and a submersible pump which on demand take water from the cleanest part of the tank through a floating suction filter supplying filtered rainwater to the break tank, Combi unit or Pressurised control panel.

Filtered rainwater is then supplied to point of use on demand. It is possible to have one, or more, break tanks at any level in the building when combined with a booster unit sized for the specific building requirements.

Our Combi System

The Combi unit combines the best of both worlds, giving a 400L or 620L buffer tank within the control panel to protect the pump and enable an above ground mains water top up. During periods of low rainfall  our mains water top-up provides a continuous failsafe supply.All our products are compliant with the Water Supply (Water Fittings) Regulations 1999.

Our systems page has more information on the individual tanks and control panels and full data sheets are available for download.

We would also recommend you view our short 2 minute video which shows how the system works in more detail.

Quick Quote

“Stormsaver has helped us to upgrade the existing rainwater harvesting system. We desperately needed support and within one month they had attended site, carried out a survey, manufactured the new control panel, and installed and commissioned the system. Together the team at Stormsaver responded quickly, understood our requirements, and worked to ensure that we had the best solution. Their knowledge and expertise have resulted in us now having a fully functional, efficient rainwater harvesting system and we would highly recommend that other clients who need their existing rainwater system upgrading, contact Stormsaver for support.”
