Rainwater harvesting involves the collection of rainwater for reuse. In the majority of situations the rainwater is captured in roof guttering and directed via a down pipe to a rainwater collection tank. There has been widespread adoption of rainwater harvesting in European countries like Germany and Belgium. In the UK the domestic market has been developing with increasing sales of basic collection systems mainly used for garden irrigation.

The greatest opportunity to benefit from installing rainwater harvesting lies with the commercial and industrial sectors. Generally demand for potable and non-potable water is higher in these sectors and they possess the capability to harvest larger quantities of water because of the size of their premises.

The System UVEX rainwater harvesting system comprises a method to collect rainwater, apply filtration, treat it with UV to attain and maintain non-potable quality and store the rainwater ready for reuse when required. Rainwater harvesting provides a simple, cost effective solution for organisations that are keen to demonstrate their positive attitude towards the environment and a desire to conserve precious resources.
