SWSI Phase 2 Technical Roundtable <br />Water Conservation and Efficiency <br />inf ormation could be data f rom SWSI Phase I or information and recommendations <br />developed as part of the TRT process. <br />1. Technical Roundtable Discussions <br />The purpose of the Water Efficiency TRT during Phase 2 of SWSI is to develop an <br />understanding of the water conservation and efficiency measures that can be <br />implemented and the associated benef its and impacts of their implementation. The <br />goals of the TRT will be to evaluate what conservation and efficiency measures could <br />reliably be implemented and potential areas f or implementation. One of the key <br />findings of SWSI was that water conservation will be an important tool for most M&I <br />providers to meet 2030 water demands, but that conservation alone cannot meet all of <br />the 2030 water demands and there will still be gaps in headwater areas and in areas <br />that are solely on non-renewable groundwater. The SWSI report identif ied various <br />levels of conservation and potential water savings from the progressive <br />implementation of additional measures. <br />For the purposes of the discussion in this paper, water conservation and efficiency <br />will be defined as follows: <br />^ Water conservation includes measures that are designed to reduce total annual <br />water use on a permanent basis and may include measures that reduce overall <br />consumptive use (CU), such as changes f rom high water using to lower water using <br />landscaping and crops. <br />^ Ef ficiency improvements are measures that are designed to reduce the amount of <br />water f or a particular use, but may not result in a reduction of CU. Examples of <br />water efficiency measures include water rates, the implementation of new <br />irrigation technology, or landscape audits that reduce irrigation application rates to <br />urban lawns or conversion to more ef ficient agricultural irrigation practices. <br />Efficiency measures also may reduce return flows. <br />^ Temporary drought restrictions are implemented during droughts by M&I <br />providers and are designed to temporarily reduce water demand so that water <br />supplies will be sufficient to meet vital uses until the drought has ended and the <br />water supply has recovered to acceptable levels. Examples include water <br />restrictions that limit the time or amount of water that can be applied to urban <br />landscape. These temporary measures are not classified as permanent water <br />conservation. <br />Options f or developing water conservation and efficiency alternatives are presented <br />below. <br />~• ~ <br />DRAFT <br />2 <br />S:IMEETINGSITECHNICAL ROUNDTABLEITRT MEETING - SPECIFICIWATER EFFICIENCYISWSI WATER EFFICIENCY TRT BRIEFING.DOC <br />
