The use of Rainwater Harvesting systems in commercial and public sector developments is not only good for the environment, but has a positive financial effect.

New Haden pumps Enviro-Pac system collects rainwater, filters, stores and provides this on demand for uses such as WC flushing, irrigation, car washing etc. If you have a large roof area & a high demand for non-potable water it is possible to save on the use of mains water.

• Rainwater falling on the  roof, is collected by the guttering and drops via the downpipe
• At the foot of the downpipe rainwater is diverted through a  filter to the underground storage chamber
• Filtered rainwater is stored in the  chamber
• Submersible pump inside the chamber delivers water via a pressurised  system to wc’s
• Overflow to soakaway or existing surface water drain
• Control unit senses when the water is being drawn and automatically  start  the pump to deliver the  required water pressure
• Option Filtered water can be pumped into a header tank and appliances fed by gravity feed  - This offers the advantage  of additional storage &  maintains the system in  the event of power failure
