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

How does a non pressurised system work?

Rainwater is channelled from the roof 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.

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 supplying 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 mains water 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.

Stormsaver provide two options of non pressurised systems; Singlex and Standard

The Singlex non pressurised control panel includes our unique automatically backwashing fine filtration unit, which has been tested to a million backwashes. This is always recommended where the client requires the highest quality of water or where a UV disinfection unit is to be included within the system. This ensures that when the rainwater passes through the UV unit it is filtered to 35 microns, thereby reducing the amount of particle build up on the UV tube so that the disinfection remains effective.

The Standard non pressurised control panel is much smaller and provides the simplest levels of control required to operate the system and is ideal for those watching the pennies, or who do not need such high levels of filtration.
