Why are Water Consumptions Calculations required?
Approved Document Part G of the Building Regulations requires all new dwellings (including conversions) to use less than 125 litres of water per person per day. This can be demonstrated by supplying Building Control with an appropriate water efficiency calculation at the design stage and on completion of a build.
Asides from the national mandatory requirements of Part G of the Building Regulations, there are also provisions for local planning authorities to set a more stringent water consumption rate of 105 litres per person per day, as part of their localised sustainability requirements. This often takes the form of a planning condition for the development.
Water Efficiency Calculations FAQs
How are Water Efficiency Calculations completed?
The projected water usage of a property is calculated in accordance with the Government’s published methodology “The Water Efficiency Calculator for New Dwellings”. The calculation considers the following:
- The capacity of any installed baths
- The flush capacity of all installed toilet cisterns
- The flow rate of installed taps and showers including any restrictors that may have been installed
- The specific water consumption of any installed washing machine
- The specific water consumption of any installed dishwasher
- The efficiency of any installed water softeners
- The effect of any installed rain water or greywater harvestings systems
When should I complete a Water Consumption Calculation?
Despite the above, it is commonplace for clients to only request a water efficiency calculation once they have finished building and the water fittings have been installed. Whilst this reduces the choices available for achieving compliance, we can still advise on any necessary remedial options if the initial water efficiency calculation fails.
What happens if I fail the Water Efficiency Calculation?
If the water efficiency calculation fails when property is built and all sanitary ware and water outlets are in place, compliance will still be achievable through the careful selection and installation of flow restrictors to taps and showers.
