Water Supply Reserve Account - Grant Application Form Form Revised nray 2007 The objectives and conduct of the pilot project proposed by this application differs from the ECCV pilot in several Nvavs: • The project addressed statewide objectives that were identified through consensus building process by the stakeholders participating in the MTW. The result of this consensus process assures the testing perfonned during the proposed pilot project provides relevant information to stakeholders a«d the state at large, • The project includes testing in two basins providing a better statewide assessment of the feasibility of ZLD; • The pilot tests involves separate water quality issues not addressed by the ECCV pilot, including selenium; • The pilot program w-ill test additional non-proprietaiv technologies, not tested by ECCV; • The project leverages additional sources of funding; • Management by Aw1vaRF taps into the most recent research in the area, assuring the pilot test is relevant and consistent with current research in this field. The MTW realizes that ZLD technologies are inherently energy intensive and alternative energy sources may be a cost-effective way of supplying power to ZLD systems. In a parallel effort, the MTW is developing the project "`Feasibility Investigation and Preliminary Design of Renewable Energy- Systems for Zero Liquid Discharge Concentrate Management." Funding for this energy-related project is NOT the subject of this grant request, rather other ffinding sources are being developed to finance it. When funded, the Energy System Project Nvill run concurrently Nsith the proposed pilot project. The Energy System Project will use data developed by this pilot project to provide potential users of ZLD with an assessment of alternative energy- options which may lower the operating cost of ZLD while improving environmental stewardship. Siil)I)orts Colorado °s Econon is Vitality Reliable, safe and affordable municipal water is fundamental to the state's economic vitality. This project will assist in using poorer water quality sources for municipal supply, reducing demands on agricultural supplies and assuring membrane treatment remains a viable technology in Colorado. Experience gained by the project Asill establish Colorado as a leader in this area with potential economic benefits to the statewide participants in the project. 4. Please provide an overview of the water project or activity to be funded including - type of activity, statement of what the activity is intended to accomplish, the need for the activity, the problems and opportunities to be addressed, expectations of the participants, why the activity is unportant. the service area or geographic location, and any relevant issues etc. Please include any relevant TABOR issues that may affect the Contracting Entity. Please refer to Part 2 of Criteria and Guidance document for additional detail on information to include. As indicated above, this project has been developed by the MTW to implement its reconuriendation that ZLD treatment technologies be pilot tested ni Colorado. The Workgroup has assembled a team of project proponents from across the state. The MTW has identified two geographically separate locations in different basins for testing. This approach illustrates the statewide applicability of the test results. In order to assure the highest scientific standards for the project, as well as to dray upon the experience of MTW ZLD Application - Submitted 11
