EXHIBIT A SCOPE OF WORK I. BACKGROUND The City developed a reclaimed water system in 1999 to provide cooling water to a power generating plant located southeast of the City. In subsequent years, the City has added as reclaimed water customers a cement manufacturing plant and a proposed golf course. The University's need for new thermal plants resulting from continued campus growth comes at a time when Texas State, the City, and others who rely on the Aquifer are focused on diversifying water supplies, partially in support of the EAHCP and the regional effort to meet the increasing water supply needs of the region. The City and Texas State have conducted a study of the feasibility of expanding the existing reclaimed water system to serve industrial and irrigation needs of the City, Texas State, and private sector users. The feasibility study identified and categorized existing and potential uses and developed a proposed plan for expanding the existing reclaimed water system. The water management needs of the study area are summarized in the following five primary components: • Develop reliable sources of water supply; • Ensure that water supplies protect and promote public health; • Develop water management strategies that enhance and restore the local environment; • Minimize the costs of developing new water supplies by full utilization of local water sources; and • Make water resource management an integral part of local economic development. The feasibility study examined an expansion of the reclaimed water system in four phases over a period of 27 years. The following table depicts the multi -year phased approach of the expansion of the reclaimed water system: Phase Year Service Area(s) Potential Users Features Capital Cost Added/ Annual Demand 1 2015 Texas State/ Texas State Extend service to Texas State $3,036,300 Downtown Thermal Plants thermal plants.
