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%.
