RECOMMENDATIONS FOR WATER REUSE AND RECYOLING I. No/Low cost Strageties for Remainder of FY 88-89 A. Establish a Water Reuse policy for City operations. Suggested wording for a policy statement: "The reuse of treated wastewtaer effluent is a major means of reducing demand on the aquifer. Therefore the current and potential uses for reclaimed water in City owned and operated failities will be identitifed. A cost/benefit and feasibility analysis of these uses will be made and desirable reuse programs implemented. . See HCWDB recommendation p. 6-6 in the Hays County Regional Water and Wastewater Study Draft Report, Oct. 1988 and p. 25 in the Executive Summary of the Regional Water Resources Plan Draft, July 1988. B. City Water Management Dept. staff identify reuse and recycling operations on-going within the City limits to get: 1. Baseline data on current water savings from existing reuse and re~~cling efforts. Note: This survey could begin with the largest water users such as local industry and large commercial users to identify the quantities of water used in their processes, cooling towers and heating systems. 2. Identifiaction of potential candidates in the City for wastewater or process water reuse and recycling. 3. Information for publicizing the benefits and cost savings for reuse/recycling as an incentive for similar operations in the City adopting these pratices. II. Proposed items for FY 89-90 budget A. City Planning and Building Department identify large scale new developments for on-site water reuse/recycling and revise planning requirements and building codes to effect implementation. These should include: 1. New Planned District Developments, PDDs, Municipal Utility Districts, MUDs, and Multi-Family housing projects for dual system greywater installations to provide irrigation and limited indoor use such as toilet flushing. 2. New Industrial Developments for process and operations water reuse/recycling. 3. New commercial operations using large quantities of water such as car washes. III. Long Term Planning Strageties and CIP Projects A. City Water Management Dept. identify and research potential large quantity reuse projects. These feasible and desirable projects will be included in the CIP program. Suggested examples for investigation: 1. Pumping reclaimed wastewater into the Edwards Aquifer recharge zone. See reference to City of Palm Springs, Cali f. project p. VI-6 and case study on El Paso, Tex. project p. VI-5 in Water Conservation Working Handbook published by the Edwards Underground Water District, and pp. 5-16, 5-17, in the HCWDB Water and Wastewater Study Draft, Oct. 1988.
