RDE717 Water Resource Zone Integrity Assessment

The Water Resources Planning Guideline (March 2023) sets out how water companies should develop their water resources management plans. Part of this process is defining a water resource zone; an area within which the sources of water and distribution of water to meet demand are largely self-contained (apart from any agreed bulk transfers). The process by which to define a water resource zone is set out in the Environment Agency's technical guidance 'Water Resource Zone Integrity' (2016), and also summarised in the supplementary guidance 'Water Resource Zone Integrity' (March 2021).

Aims: The project aims to review and update the water resource zone integrity guidance, including the definition of a water resource zone, in the context of recent developments in understanding of demand, climate change, drought, and sustainability reductions, and the implication of these for water resource zone performance.
