Water Demand Analysis and Forecasting

Hazen and Sawyer has cultivated long- and short-term forecasting methods that stretch across a spectrum of technical detail and client needs, from traditional approaches to detailed approaches that incorporate multiple causal factors and uncertainty. We have also developed thoroughly-quantified, utility-specific methods for assessing current and future water savings due to active conservation programs and passive increases in efficiency in response to increasing market prevalence of high-efficiency fixtures.

Demand Forecasting: We regularly extend beyond typical forecasting methods to incorporate the subdivision of demand into sectoral and geographic components, each with their own demand intensities, driver units, local land use characteristics, and growth trends, leading to composite forecasts.

Water Demand Research: Our portfolio includes research projects covering a diverse array of knowledge areas within the water demand field, including recommendations for customer information and data collection/processing needs to serve water demand planning and management

Demand Forecasting
The simplest and most traditional long-term forecasts are usually based on per capita demand intensity and population projections. We regularly extend beyond those methods to incorporate

  • subdivision of demand into sectoral and geographic components, each with their own demand intensities, driver units, local land use characteristics, and growth trends
  • modeling and forecasting of demand intensity itself as a function of demographic, economic, weather, and efficiency factors
  • uncertainty and variability in future demographic, economic, weather, and climate conditions that govern demand intensity and driver populations, allowing Monte-Carlo probabilistic forecasts
  • Water Conservation and Efficiency Analyses
    Hazen and Sawyer is also well-steeped in conservation planning and end-use analyses of water efficiency. We go beyond the application of standard assumptions to assess conservation potential and achievement, performing deep detailed profiles of actual customer-level water use characteristics.

    Water Demand Research
    Through eight separate engagements with the Water Research Foundation over the last five years, Hazen has performed more research into methods for characterizing, managing, and forecasting water demand than any other private firm in the world. These research efforts have been supported by case studies involving utility participants across the United States and Canada.
