UK Public Water Supply Demand Projections Under Climate Scenarios

Projections detail future public water supply demands from 2025 to 2055. The Environment Agency produced this data under four distinct water resource modelling scenarios: Do Nothing, Low, Central, and High. It provides estimates at national, regional water resource group, and water company water resource zone scales.

Use Cases

• Modeling demand variation by comparing projected water volumes across the Do Nothing, Low, Central, and High scenarios.
• Analyzing spatial disparities in future water stress by examining demand estimates at national, regional, and water resource zone scales.
• Assessing the impact of population growth and climate change on public water supply by tracking demand drivers over the 30-year projection period.
• Evaluating infrastructure investment needs by correlating high-demand scenarios with specific water company resource zones.

Strengths

• Projections span a 30-year future period from 2025 to 2055.
• Data is structured across four defined modelling scenarios for comparative analysis.
• Spatial granularity includes national, regional, and local water resource zone scales.

Limitations

• The dataset contains modelled projections, not observed measurements, introducing inherent uncertainty.
• Specific row counts, column details, and underlying driver data granularity are unknown.
• Geographic coverage is limited to the United Kingdom.
