Water Efficiency Calculations - Have You Been Caught Out?

Changes to Part G of the building regulations in 2010 saw the introduction of a mandatory requirement to limit water consumption in new-build properties to 125 litres per person per day.
The consumption (based on occupancy) is established using the CLG approved water efficiency calculator. The outcome of this calculation would then form the plumbing specification provided to installation contractors allowing them to fairly and competitively price for the works.
However, in some cases designers / Architects are largely ignoring the water calculation requirements at the building design stage creating significant problems providing the required certification. The situation is made worse by the fact that regulations only stipulate that certification is required with supporting calculations on completion of the works.
·         Have you found yourself in this sort of situation recently?
·         Have you been pushed to carry out works in line with Developer/ Architect/Designer specifications only to find there is no consideration for the water efficiency certification?
·         Have you faced this problem and been left with a bill for remedial works?
We would like to propose an amendment to the government but before we can do this we need evidence – this is where we need your help. If you have been affected by the water efficiency calculation requirements please tell us about your experiences with real life examples, using the APHC Blog below or if you’d prefer by emailing us at info@aphc.co.uk (please put ‘Water Efficiency – Member Feedback’ in the subject line)

  2. It is very important that large companies should promote water efficiency. They should always observe to detect if there are leaks or if any supply pipes needs repair.

  3. I agree, the importance of water efficiency plays big roll in any construction project. Unfortunately, it is somehow being overlooked by architects and engineers. Something must be done.
