Water Supply Reserve Account - Grant Application Form <br />Form Revised nlav 2007 <br />Bawl Amount Approval Date Comment <br />Arkansas $25,000 June 11, 2008 Funding contingent upon <br />obtaining $75.000 from other <br />basins. <br />Metro $50,000 June 12, 2008 <br />S. Platte $25,000 July 8, 2008 <br />In addition to the financial commitments from the above Roundtables, the Colorado Basin Roundtable <br />will provided a letter of political support for the project. <br />4. The water activity meets the provisions of Section 37-75-104(2), Colorado Revised Statutes. The <br />requirements/language from the statute is provided in Part 3 of the Criteria and Guidelines. <br />Membrane treatment for municipal drinking water supply is the best technology for producing potable <br />water from lower quality-/impacted sources that will meet, and often exceed, regulatory requirements <br />adopted pursuant to the federal Safe Drinking Water Act (SDWA) and/or consumer requirements. <br />Currently, many sources of water in the Arkansas and South Platte River Basins exceed the <br />regulatory maximum contaminant level under the SDWA for one or more parameters and/or have <br />high levels of total dissolved solids that are unacceptable to consumers. <br />The zero liquid discharge process technology this project will pilot is the solution that will enable <br />public water systems to use this technology for existing sources while meeting regulator-v- <br />requirements and would also allow development of new lower quality sources for municipal use. For <br />example, the implementation of ZLD technology would allow the Cities of La Junta and Brighton to <br />remove less water from the respective river system than 'kvithdraivals that occur with their current <br />membrane treatment systems while meeting the conditions of their discharge permits that require <br />reduction in the concentration of one or more contaminants. This process would make the water <br />supply for both of these communities sustainable as the combined membrane treatment/ZLD <br />technology would meet all current and anticipated future SDWA/discharge permitting requirements. <br />Membrane treatment/ZLD technology would likely allow- new sources, principally saline <br />groundwater, to be used for municipal water supply. <br />Thus, implementation of this technology would allow municipal water supplies to become more <br />sustainable and could meet a portion of the consumptive water needs in basins throughout Colorado. <br />For Applications that include a request for funds from the Statewide Account, describe how the water activity <br />meets the Evaluation Criteria. See Part 3 of Criteria and Guidelines. <br />The following is a description of how this project will meet the Evaluation Criteria for CWCB allocation of <br />fiords: <br />Promoting Collaboration and Cooperation <br />a.
