89 Water Quality and Water Resources

New development should prevent any adverse impacts on water quality and water supply by:

A. Ensuring no deterioration of water quality. Where development is seen to have the potential to cause adverse effects on water quality, appropriate mitigation to alleviate risk must be provided;

B. Ensuring developments include water efficiency measures including rainwater harvesting, greywater recycling and smart-metering;

C. Requiring development to be designed to be water efficient and reduce water consumption. Refurbishments and other non-domestic development will be expected to achieve maximum water credits in BREEAM or equivalent. Residential development must not exceed a maximum water use of 105 litres per head per day (excluding the allowance of up to 5 litres for external water consumption). Planning conditions will be applied to new residential development to ensure that the water efficiency standards are met; and

D. Working with infrastructure providers (Policy 68 ‘Utilities Infrastructure’) to protect existing water and sewerage infrastructure and manage pressure on combined sewer networks.
