Water Demand Study


In supporting its mission to provide a reliable water supply to Santa Clara County, Valley Water engages long range water supply planning to identify management and investment strategies to meet county-wide demand. An important element of water supply planning is an accurate projection of future water demands. Currently, Valley Water is updating its demand projection approach and developing a new demand model to forecast the county-wide water demand.

The model development effort includes reviewing the demand modeling approaches at Valley Water’s peer agencies; identifying potential demand models and approaches to meet valley water requirements; and developing a demand model to analyze baseline and future water demand. Using the demand model developed through this effort, Valley Water will project demands out to support several planning efforts, including:

  • 2021 Urban Water Management Plan (UWMP);
  • Monitoring of and updates to the Water Supply Master Plan;
  • Inputs to Valley Water’s water supply planning model; and
  • Evaluating conservation programs and capital projects.

The new demand model will be used as a planning tool to support periodic updates of Valley Water’s demand projections as new data and information become available and the planning horizon is extended.
