Water Resource Zones (WRZs)

Boundaries, names and Water Resource Management Plan 19 (WRMP19) water deficit Dry Year Annual Average (DYAA) categories for the 133 water resource zones in England and Wales.

Water deficits shown in the map below are baseline forecasts from Water Resource Management Plans (2019) submissions. Baseline forecasts give an indication of the maximum forecast dry year situation deficit (if any) for the first 25 years of the company's planning period as a percentage of demand (distribution input) without investment from the water industry. Interventions by water companies outlined in their water resource management plans aim to address these forecast deficits. Please note that this data does not reflect the actual current resource position, but instead gives an indication of the water resources pressures faced.
