Part G2 has been altered giving an improved theoretical water efficiency of  110 litres per person per day for certain new dwellings.

An alternative simplified calculation method can be adopted in most cases as shown in tables 2.1 and 2.2 .If a designer states he is adopting this method then this may be treated as showing compliance. eg

Any water fittings must be in accordance with table 2.1 of approved document G for a water efficiency of 125 litres per person per day or if required by planning table 2.2 for an efficiency of 110 litres.
