Water Calculations

Water Calculations are required to comply with Part G of Building Regulations for England and Wales. All new dwellings must be designed to use less than 125 litres of water per person per day. Some local planning authorities require water levels have to be even lower. As low as 105 litres of water per person per day. This requires consideration of fittings early in the design process. For example, you want powerful power shower and large bathtub you may have to mitigate these with aerated taps, dual flush toilets and even rainwater harvesting or grey water recycling.
