Severn Trent is supportive of this policy, particularly bullet point 1. One key element of reducing energy demand and carbon impact in households is water usage. One of the key findings of an Environment Agency report named ‘Greenhouse gas emissions of water supply and demand management options’ - link is that “89 per cent of carbon emissions in the water supply - use - disposal system is attributed to "water in the home" and includes the energy for heating water (excludes space heating), which compares with public water supply and treatment emissions of 11 per cent.”

It is therefore pertinent that this policy include measures to design and build new developments that are fitted with water efficient fittings, meeting the optional requirement in Building Regulations of 110 litres of water per person per day (l/p/d), this goes beyond the 125 l/p/d that is specified in Part G of Building Regulations.

We recommend that if this is not already a policy within your Local Planning documents that it is updated to be included to support your Net Zero ambitions. We would recommend the inclusion of the following wording:

‘Development proposals must demonstrate that the estimated consumption of wholesome water per dwellings should not exceed 110 litres of water per person per day.‘
