<br />Metropolitan Water Supply Investigations - Phase II Plan of Study <br />8/16/94 5:04 PM <br /> <br />Page 16 <br /> <br />Review modeling results from other studies for projected streamflow water <br />quality under different assumed scenarios of effluent discharge, reuse and <br />exchange. <br /> <br />c) Output <br /> <br />A matrix of proposed alternative uses and water quality parameters will be <br />used to display water quality thresholds for reuse of effluent. This <br />information will be used in the assessment of treatment technologies to identify <br />required levels of treatment for various alternative uses. <br /> <br />d) Sub-Task Leader: Jean Boyer <br /> <br />8. Sub-Task 4h: Assessment of Treatment Technologies <br /> <br />a) Purpose: <br /> <br />Compile existing information on appropriate technologies for treating effluent <br />for effluent management purposes. Assess treatment effectiveness, relative <br />costs, potential for future implementation. <br /> <br />b) Approach: <br />Interview representatives of Metro Wastewater Reclamation District, Colorado <br />Department of Health and U. S, Environmental Protection Agency to compile <br />list of treatment technologies. <br /> <br />Review and summarize existing i.nformation (reports, literature, unpublished <br />studies) and assess appropriate treatment technologies (e.g. rapid infiltration <br />basin technology). <br /> <br />Summarize levels of effectiveness and costs for the various technologies <br />available. Develop criteria to compare the effectiveness of technologies. <br /> <br />c) Output: <br /> <br />Summary memorandum documenting the investigation of available <br />technologies which represents, in an understandable way, the alternatives <br />available to provide effluent of an acceptable quality for potential identified <br />uses. Develop a comparison of the various alternatives, including both <br />quantitative (costs, water quality parameters) and qualitative (technological <br />limitations, success of existing applications) considerations. <br />
