Domestic water usage calculations

On the 6th April 2010 Part G of the Building Regulations was amended to include limits on water use for all new homes and dwellings formed by conversion. Building Control now requires water efficiency calculations at design stage to show that water use is limited to no more than 125 litres of water per person, per day.

Why do we need to conserve water?

Water is like any other resource. If not properly managed supplies can diminish resulting in rationing.

How much water can we reasonably use?

Under current Building Regulations water usage is limited to 125litres/day/person which includes WC’s, wash hand basins, sinks, showers, baths and white goods such as dishwashers and washing machines.

North Kesteven Building Control can carry out your water calculation for as little as £12 incl VAT.
