The Household Consumption Forecasting Guidance Manual provides practitioners with technical guidance on how to forecast household water consumption. It presents methods to determine the most appropriate approaches for use, depending on the ‘level of concern’ in a water resources zone. It provides an outline of different forecasting methods, identifying data requirements and pros and cons of each. It includes sections on understanding the factors that influence household consumption, methods for segmenting customers (e.g. by meter status), dealing with weather effects, and uncertainty. The guidance has been developed to link with other UKWIR reports that support the WRMP19 water resources planning guidelines, including methods on property, population and occupancy forecasting and risk based planning. The manual sets out several alternative methods to the micro-component forecasting approach that has been used by the water industry for a number years. It also includes a case study of an imaginary water resources planner. The manual is accompanied by Supporting Guidance which presents the results of stakeholder consultation; a review of the factors that influence consumption and further background on methods for forecasting household consumption.
