What consideration has the Welsh Government given to introducing rainwater harvesting requirements, such as water butts, on new developments?
Ateb
Atebwyd gan Minister for Climate Change
In 2018 Welsh Government amended the building regulations so that when a new dwelling is erected the potential consumption of wholesome water by persons occupying the dwelling must not exceed 110 litres per person per day. The calculation method used to demonstrate compliance can take account of the water consumption savings that can be made when using rainwater harvesting systems.
The functional provisions of the building regulations also provide for differing arrangements for rainwater disposal which could include the use of water butts.
