Rainwater is collected from the roof and stored in an underground or above ground holding tank.
The system is supplied with a filter to remove leaves and heavy debris from rainwater before entering the tank.
The system is equipped with an internal pump to propel the rainwater when required.
A floating suction fitting is connected to the pump which extracts rainwater from the cleanest layer
of the tank. Excess rainwater is removed from the holding tank by means of an overflow and passes into
the storm drain. A large range of commericial systems are avaialable any are tailored to individual requirements.
Pressurised System
Stored rainwater is pumped at normal pressure directly from the holding tank to the services. A mains connection is
fitted to the holding tank and acts a substitute when rainwater is depleted. The mains back up is configured to
ensure minimum mains water is used. This system omits the requirement of an elevated header tank and it a suitable
option where space is restricted for an elevated tank.
Non Pressurised System
Stored rainwater is pumped at normal pressure directly from the holding tank to an elevated header tank or attic tank.
The services are fed by gravity from the header tank. The specially designed header tank is fitted with control
devices to switch to mains water when required.
Additional controls may be fitted within the header tank which are not electrically dependant and therefore operational
during a power cut. This ensures un-interrupted supply of water to the services.
