SUMMARY: Utilities are increasingly facing challenges that include cost constraints, aging infrastructure, increased regulations, source water quality, minimizing the impacts of droughts and other extreme events, and balancing competing stakeholder objectives. This webinar will provide an overview of the analytical tools available to water supply system managers and operators to support robust, multi-objective decision-making under increasingly complex and uncertain conditions. We will demonstrate how supply and demand forecasting tools can be combined into a single Decision Support System (DSS) that can be used in both long-term planning and near-term operations.

For most decisions associated with reservoir operations and management, the largest source of uncertainty stems from future reservoir inflows. Ensemble hydrologic forecasts quantify this uncertainty and can assist reservoir managers in managing adaptively and understanding the risk associated with their decisions.

For example, a municipal water supply reservoir may use hydrologic forecasts to estimate the probability of being able to reliably meet future demands and evaluate the need for conservation measures. A water demand forecast serves as a basis for water supply system planning by building expectations about water sales revenue, and is also a key component of evaluating supply reliability, estimating need for capital improvements, and creating a baseline for evaluating impacts of changes in water rates and demand management (water conservation) activities. Effective demand forecasting requires analysis of historical and anticipated water demand patterns, long-term water efficiency potential, and impacts stemming from acute water shortages.

Combining hydrologic and demand forecasts with a water supply systems model can provide solid analytical support and documentation with which to defend decisions and demonstrate the risks associated with alternative capital or operations policies.


John Clayton, Hazen and Sawyer, P.C.
John M. Clayton, Ph.D. P.E., is an environmental engineer in Hazen and Sawyer’s Atlanta Office. Dr. Clayton has expertise in modeling and forecasting of water demand and supply (including probabilistic and mechanistic methods), supply reliability analysis, water system operational modeling, water master planning and drought planning, and estimation of climate change impacts on water systems and demands. He has been with the firm since 2003 and currently serves as the Mid-Atlantic regional leader for the firm's Water Resource Management practice group.

Josh Weiss, Hazen and Sawyer, P.C.

Dr. Weiss performs research, studies, modeling, and analysis in all aspects of water resources management and drinking water treatment. Dr. Weiss has extensive knowledge of the use of system models to optimize water supply operations. Dr. Weiss currently serves as task leader for deployment of an Operations Support Tool for New York City’s Department of Environmental Protection. The OST will serve as a real-time tool to help guide near-term and long-term water supply operations for the City.
