Abstract : The IWR-MAIN Water Use Forecasting System is a sophisticated and flexible computer program designed for estimating and forecasting municipal water requirements. The IWR-MAIN System is sectorally, spatially, and seasonally disaggregate. Water requirements are estimated separately for the residential, commercial/institutional, industrial, and public/unaccounted sectors of the study area. Within these major sectors, water use estimates are further disaggregated into individual categories such as metered and sewered residences, commercial establishments, and three-digit SIC manufacturing categories. Definition of the study area as a city, county, or water utility service area provides for spatial disaggregation. Additionally, IWR-MAIN forecasts are presented as summer daily water use, winter daily water use, average daily water use, and maximum-day summer water use. The IWR-MAIN System can also produce water use forecasts which take into account long-term impacts of demand management or conservation practices that may be or have been implemented in the study area.
