Impact of Climate Change on Demand
UK Water Industry Research (UKWIR) and Environment Agency
RPS was commissioned by UKWIR and the Environment Agency to derive evidence based estimates of the impact of climate change on the future demand for water.
A model was produced in partnership with HR Wallingford to enable water companies to confidently adjust demand forecasts for PR14. Key tasks comprised of analysis of weather–water demand relationships to derive statistically robust estimates of the impact of climate change on both domestic and commercial components of water demand. These derived relationships underpinned simulated climate change scenarios which ultimately provided the evidence to advise water companies on adjustments to water demand calculations.
The scope of the project included; a comprehensive literature review to fully understand the impact of climate change on demand, conduct an industry based workshop to present the methodology and engage with key stakeholders to fully understand their requirements and preferences, weather-water demand analysis, and facilitate a dissemination workshop to present the conclusions of the research and effectively communicate recommendations for adjusting water demand forecasts.
