Water Supply Reserve Account - Grant Application Form Fonn Revised nlay 2007 The project addresses issues related to making additional poorer quality water supplies available for municipal water supply and is applicable to multiple water supply interests in all basins. The lack of viable options for disposal of concentrate disposal from membrane treatment processes has restricted the use of this higlnly effective treatment technology for drinking water production. Membrane technology is essential in treating water of lower quality to drinking water standards. This technology also improves the efficiency of the treatment process, permitting a greater percentage of the water treated to be available for consumption. The ability_ to treat lower quality- water voll assist ni meeting fiiture municipal water supply needs. b. Promote Cooperation and Collaboration A wide variety of entities are represented in this application and are ivorl< irIg together through a process of cooperation and collaboration to develop the necessary information contemplated by this pilot project. Concentrate disposal is a pressing statewide issue currently being addressed by the MTW (current e- mail list contains 73 participants), a collaborative group established under the auspices of the Water Quality Forum. The MTW has brought together a broad spectrum of interests who are cooperatively working together to develop solutions to the problem of environinentallv acceptable disposal of membrane treatment concentrate. The pilot testing of ZLD technologies was identified by the MTW as a critical step ni solving the problem of concentrate disposal in Colorado. The collaborative nature of this project is illustrated by the broad range of project proponents included in Table 2. These proponents have agreed to support the project either through direct financial contribution, in-kind services or participation in project planning. MTW ZLD Application - Submitted 6
