Water Supply Reserve Account - Grant Application Form Fonn Revised nlay 2007 The project will provide information and assistance to drinking water suppliers desiring to use membrane treatment in situations where a permit for discharge of the concentrate cannot be obtained because such discharge would cause water quality- standards adopted by the Water Quality- Control Commission (WQCC) to be exceeded. Zero liquid discharge (ZLD) of membrane treatment concentrate (e.g. treating all of the raw- water for drinking such that a dn- solid remains) has been identified as the oniv available technology for environmental compliance at most locations where membrane treatment systems are expected to be located in Colorado. The project will be implemented at two public drinking water utilities, managed by the American Water Works Association Research Foundation, the preeminent drinking water research organization in the United States, with assistance from the Membrane Treatment Workgroup (MTW) and oversight by the Colorado Department of Public Health and Enviromnent. The MTW was established as a Workgroup under the Water Quality- Forum at the direction of the WQCC. The MTW was tasked with: • Taking a leadership role in assuring that membrane treatment technologies remain a viable option for drinking water and other uses within Colorado, • Developing recommendations for resource recover- and disposal for membrane treatment concentrate that are cost effective and address envirommental impacts. The Scope of Work provides additional detail on the proposed scheme for funding and managing the project. 2. The water activity is consistent with Section 37-75-102 Colorado Revised Statutes. The requirements/language from the statute is provided in Part 3 of the Criteria and Guidelines. The project will pilot technology for relatively small water flows at two locations in Colorado. This project will not restrict the ability of the holder of a water right to use or dispose of that water right in any matter permitted by Colorado law and is consistent with Section 37-75 -102. The water activity undenvent an evaluation and approval process and was approved by the Basin Roundtable (BRT) and the application includes a description of the results of the BRTs evaluation and approval of the activity. At a minimum, the description must include the level of agreement reached by the roundtable, including any minority opinion(s) if there was not general agreement for the activity-. The description must also include reasons why general agreement was not reached (if it was not), including who opposed the activity and why- they opposed it. Note- If this information is included in the letter from the roundtable chair simply reference that letter. Table 1 summarizes fimding requests/approvals from BRTs. The letters of corm utment are attached. Table 1 Basin Funding Requests MTW ZLD Application - Submitted 4
