Water Demand & Forecasting


This project describes models, methods and practices currently used to forecast long-term demand in support of water resources and infrastructure planning and management, and the deliverables discuss how current practices have evolved over time. The research team considered the accuracy of different forecasting approaches by comparing actual with model-estimated demands. The team identified the extent to which forecasting models, methods, practices and communications influence decisions about utility plans and actions. Finally, this project developed recommendations to help improve the role and effectiveness of demand forecasting practices and different types of communication strategies on water resource and infrastructure planning and decision-making.
