Rain Water Tanks

Rainwater harvesting systems are becoming very popular means of recycling our natural resources in both private and public developments. Rainwater is collected and stored in the unit until required. There are two types of units available as follows:

Pressurised System
Rainwater is collected from the roof drainage by the underground vortex filter. Debris is filtered from the rainwater and 85% of it is diverted into the system, while the balance runs to the storm drain as does excess water from the tank. Water is supplied on demand by a submersible pump, through a suction filter to the point of use. The pump is controlled by a combined pressure switch/flow controller, which switches the pump on and off when required. An overflow trap provides a water seal against any foul odours from drains. An option level indicator is available, which provides a visual indication of the water level.

Pumped System
Rainwater is collected in the same way as the pressurised system. Water is then pumped on demand by means of a submersible pump to a header tank in the attic and finally to the point of use. The pump is controlled from a panel that receives inputs from a float switch in the header tank to detect demand and a flat switch in the header tank to provide dry running protection. An overflow trap provides a water seal against any foul odours from drains. An option level indicator is available, which provides a visual indication of the water level. Standard header tank sizes are 25, 50 and 100gallons.
