Water Supply Planning

We bring together the most advanced techniques in the world for anticipating future demands, modeling future supply availability, and assessing water supply reliability while considering both supply and demand.

Water Supply Modeling: Hazen has developed dynamic water supply models for some of the most complex and diversely-sourced systems in the United States. Our modeling approaches simulate how raw water is moved from sources to points of service, incorporating logic on how water routing decisions are made and impacts on water quality and supply cost.

Integrated Water Resource Planning: Using integrated simulations, we analyze how the system responds dynamically over time to ranges of future supply availability relative to need. We then identify proper mixes of structural and non-structural solutions that maximize supply reliability while safely deferring costly new infrastructure development until lower-cost operational and programmatic options have been exhausted.

Supply Reliability and Risk: Reliability is not simply defined as a yes/no question to whether demand can be met 100% of the time. Instead, we view and quantify reliability in broader terms, as a physically descriptive performance indicator. Through the exercise of expressing reliability descriptively and understanding the cost of maintaining or improving reliability, our clients gain a deeper understanding of their own risk tolerance and can communicate the reliability-based ramifications of their decisions in clear physical terms.

We apply these capabilities to address a variety of multi-faceted water supply planning problems, such as

  • assessing water supply reliability in terms of susceptibility to water shortage episodes, especially for complex and interconnected multi-source systems
  • optimizing water supply operations within such systems in terms of costs, physical reliability, and other criteria
  • forecasting water demand using methods that incorporate and portray impacts of uncertain future socioeconomic, weather, and climatic conditions
  • assessing water conservation programs, natural improvements in water use efficiency, and their impacts on demand
  • designing effective demand management programs, including evaluating the cost to achieve savings from these programs as an alternative source of supply
  • designing emergency supply operation and demand management plans to manage water shortages due to drought and transient infrastructure interruptions
  • quantitatively evaluating the effects of local climate change on any of these analyses
  • using any of these analyses as a basis for planning future supply expansions
  • We embrace the fact that Water Supply Planning is far from a one-size-fits-all discipline. Through our core expertise in water supply modeling, demand analysis and forecasting, integrated water resource planning, and evaluation and management of water supply reliability and risk, we assemble sophisticated planning solutions that meet the needs of each our individual clients.
