Specifications include, but are not limited to: In 2020, the Great Salt Lake Advisory Council and Weber Basin Water Conservancy District studied the impact of water conservation on water resource planning (that is, the timing of large water development projects). Of four Water Conservancy Districts within the study scope, three need conservation beyond the regional conservation goals before approximately 2055 to avoid large future water development projects. Currently, M&I water conservation implementation is inconsistent because incentives and programs available for M&I water conservation vary and depend on local water values. The study will build upon findings in the 2020 Conservation Impacts Study. Specifically, the project will examine the way population growth interacts with land use changes, refine water supply, and water demand data and estimate and rank the costs of M&I water conservation opportunities. Water reuse, as it relates to M&I conservation strategies will also be explored in this study. Building upon the 2021 Great Salt Lake and Water Reuse report, this study should consider how sewage effluent reuse impacts conservation efforts and the lake. Finally, these M&I conservation costs will be compared with future large water development projects, costs of Great Salt Lake (GSL) dust control, and costs of agricultural conservation. This study should be closely coordinated with the current Conservation Toolbox efforts, currently in development, sponsored by the Great Salt Lake Advisory Council. Study tasks are as follows: Quantify the amount of conservation that has been achieved through M&I conservation including secondary metering and landscape conversion incentives programs. Quantify a potential range of M&I conservation possible within each GSL sub-basin. Coordinate closely with the Division to report turf cover estimates by basin generated from the Divisions greenspace model. Study how land and water use changes over the past decade correlated with population increases and water use to identify patterns or trends. Identify potential M&I water conservation opportunities and estimate costs. Normalize costs by the amount of water conserved. Compare M&I water conservation opportunity costs with costs of future large water development projects, costs of wastewater reuse projects, costs of GSL dust control, and costs of agricultural optimization. Work with the Division to update the Division’s Water Demand Model with information from Tasks 4 and 6. Develop a proposed conservation standard for the amount of water needed for each equivalent residential connection for future growth in coordination with the Division, Division of Drinking Water, Division of Water Rights, water conservancy districts, and municipalities.
