Nant Yr Arian Visitor Centre
Nant yr Arian Visitor Centre

Project for Forest Enterprise Ceredigion, Wales.

Rainharvesting Systems Ltd. provided the rainwater harvesting system for this unusual visitor centre in Wales.

Water

A rainwater harvesting system channels water from the roof to a 10,000 litre tank for flushing the toilets and the bike wash, reducing mains water consumption by 25%. Dual flush cisterns in the toilets, push taps in the basins and other efficient plumbing fittings, equipment and controls have further reduced water consumption by 10%.
