Rainwater harvesting simply involves the collection of rainfall from our roofs and its subsequent storage in a tank until required when it is pumped to the point of use.

Rainwater is captured from the roof and channelled via normal guttering and down-pipes to an underground storage tank where it is filtered. A submersible pump then either delivers the water to a header tank in the loft space or directly to a service on demand. The size of the storage tank will be determined by the collection area available and the likely usage.

Some re-plumbing is necessary to separate the harvested water services such as toilets, washing machines & outside taps from the “potable”, drinking water services (taps & bathing).

Financial savings can be made on both the number of metered litres supplied to the property, and also on the drainage charges which are often assumed to be equal to that supplied.
