What rainwater harvesting system would suit me?

All Stormsaver comercial rainwater harvesting systems are developed to meet our clients' site-specific requirements.

The individual requirements of the system will be based on supply and demand rates being calculated as part of the building design.  Stormsaver offers a choice of systems:

Commercial Rainwater Harvesting Non-Pressurised Rainwater Harvesting System

Rainwater is channelled from the roof into the storage tank passing
an integrated filter to remove large debris, leaves etc.

Water enters the tank via an inlet calmer preventing disturbance to fine sediment on the base of the tank.

Excess rainwater flows out of an overflow which has a one-way valve and rodent protection; also skimming surface particles.

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 suppling filtered rainwater to the break tank.

This tank gravity supplies water to point of use, it is possible to have the break tank at any level in the building when combined with a booster unit sized for the specific building requirements.

During periods of low rainfall a WRAS compliant mainswater top-up provides a continuous failsafe supply.

More than one break tank can be used in a system - our team can offer design assistance to ensure the most economic solution is applied.

Pressurised Rainwater Harvesting System

This system may be required in buildings with low water consumption,
where roof space for a header tank is limited or
where a pressurised supply is required for applications.

Commercial rainwater collection and flow within the pressurised system follows the same process as the non pressurised system - the main difference being that water enters the control system and flows via a pressurisation unit as a direct supply to points of use.

In periods of low rainfall a WRAS compliant mainswater backup activates, providing a continuous water supply.

This tops-up a percentage of the underground storage tank. This type of system is only recommended within certain applications and it is best to discuss your individual requirements with our sales team.

Commercial Rainwater Harvesting System - Combi

This is a unique rain control system combining the benefits of both a gravity
fed header tank system and the pressurised supply of a boosted water system.

As with our other systems, rainwater follows the same journey until it reaches the control unit.

Instead of the normal control unit - a Combi unit is fitted, where water is stored awaiting distributuion by the energy efficient variable speed booster; providing water at pressure to a range of applications without the need for large header tanks.

The system also features mains water back up and a WRAS compliant air-break to provide a continuous water supply.
