Purpose

• Identify the efficacy of water conservation and reuse strategies across regions with varying water use/demand patterns and climate.
• Identify the efficacy of water conservation and reuse strategies across alternative future conditions (climate and urban development).

Description

• Demand for water (total municipal gallons per year or gphd) for multiple strategies of water conservation and reuse are projected for Sao Paula, Brazil, Miami, FL, Denver, CO, and Tucson, AZ. Strategies assessed are listed below (combinations of strategies were also assessed, total number of scenarios = 358):
     o Indoor Conservation
     o Conversion to Xeriscape
     o Conversion to Efficient Irrigation Systems
     o Advanced Irrigation Systems
     o Graywater Use for Toilet Flushing
     o Graywater Use for Irrigation
     o Graywater Use for Irrigation and Toilet Flushing
     o Graywater Use for Potable and Irrigation
     o Roof Runoff for Toilet Flushing
     o Roof Runoff for Toilet Flushing and Irrigation
     o Roof Runoff for Irrigation
     o Roof Runoff for Potable
     o Stormwater Use for Toilet Flushing
     o Stormwater Use for Irrigation
     o Stormwater Use for Irrigation and Toilet Flushing
     o Stormwater Use for Potable and Irrigation
     o WW Use for Toilet Flushing
     o WW Use for Irrigation
     o WW Use for Irrigation and Toilet Flushing
     o WW Use for Potable and Irrigation

Attributes

Output from the Integrated Urban Water Model (IUWM) is a daily estimate of water demand in gallons. Data can be normalized by population, households, or area. Data are also readily summarized into monthly or annual averages using multiple years of weather data.
