Analysis of Changes in Water Use Under Regional Climate Change Scenarios

Client: WaterRF
Location: Denver, CO

Hazen and Sawyer was lead investigator in Water Research Foundation project 4263, which studied anticipated water demands and use patterns under a range of climate change scenarios. Ten utilities across the country participated in this research project, serving as case studies and data sources for analyzing potential climate impacts across a wide range of geographies and climate conditions. A foremost goal of this project is to increase the adaptive capacity of water utilities in planning for and responding to climate change pressures.

Project Outcomes and Benefits

  • Provides important guidance for evaluating the importance of climate in shaping demand patterns, estimating the impacts of weather on water use, and compiling climate projections.
  • Identifies a range of potential climate adaptation options from a demand-side perspective.
  • Translates the climate projections obtained from Global Circulation Models into a scale that reflects regional or local geographical weather conditions, and presents updated regional-level forecasts of climate change.
  • Develops and demonstrates evaluation tools that can be used by the water industry to assess probable water demand impacts and adaptation options.
