Part G & Water Calculations

Under Approved Document Part G of the building regulations, all new homes and domestic conversions are required to meet a water efficiency target of 125L per person per day.

Further to this, additional credits can be achieved under the CFSH depending on a reduced level of water consumption achieved.

Therefore in order to demonstrate compliance, we carry out the calculations required by Building Control and the CFSH to provide you with a compliant sanitary ware specification that details target flow rates of taps and showers, capacities of toilets and baths and efficiency of washing machines and dishwashers.

We can also advise on the feasibility, cost and water savings of incorporating systems such as rainwater harvesting and grey water recycling.
