WRAS Guidelines for Rainwater Harvesting

WRAS Guidelines The Water Regulations Advisory Scheme (WRAS) sets out best practice guidelines for rainwater harvesting under the Water Supply (Water Fittings) Regulations 1999. WRAS are particularly concerned with preventing cross contamination of the mains water supply where a rainwater harvesting system is connected to the property.

In order to ensure that under NO CIRCUMSTANCES can rainwater back up into the mains water supply, the appropriate AA or AB airgap must be used.

Stormsaver ensure that all our header tanks or mains water back up systems are compliant with the Water Supply (Water Fittings) Regulations 1999, which is why we always recommend you purchase the system as a complete package. We have attended sites before to replace tanks supplied by others which do not meet the Regulations because it was not designed for a rainwater harvesting system.
