customers, offering rebates for low -flow urinals, offering rebates for installation of high - efficiency fixtures in new construction, and free high -efficiency toilet distribution events. 5.11 ICI Conservation Programs The City has historically implemented various programs for ICI water customers such as the annual Water Efficiency Achievement (WEA) awards introduced in 2003, and the Pre -Rinse Spray Valve Exchange program launched in 2004. These programs have been suspended but the City will continue to research and develop additional cost-effective water conservation programs for ICI customers, including a large-scale commercial rebate program which can be customized for various conservation initiatives. 5.12 Reuse of Treated Effluent In 2001, the City began delivery of reclaimed wastewater to the American National Power (ANP) facility located near San Marcos. ANP uses the reclaimed water along with Guadalupe River water to cool their power -producing turbines. The reclaimed water is used instead of treated potable water to dilute the high total suspended solids (TSS) of the river water. Once used, the water goes to an onsite reverse osmosis treatment facility where it is treated and recirculated back into the cooling system. In 2013 the City began delivering reclaim water to the TXI Hunter Cement Plant for use in plant process water and dust control. In 2016 the City added Brookfield Residential as a reclaim water customer for irrigation of the Kissing Tree Golf Course and streetscape areas. As per the Direct Water Reuse Expansion Feasibility Study completed in 2014 through a partnership with Texas State University and the Texas Water Development Board, the City has installed reclaim water mains to provide reclaim water to the University thermal plants. The University is expected to make connection and begin utilizing the reclaim water in 2021. These reclaim water mains will also be used to irrigate City parks and athletic fields along the route. 5.13 Rainwater Harvesting Rebate Program In 2009 the City implemented a rebate program for purchase of rain barrels. The City has also provided distribution of free rain barrels in conjunction with Native Plant Sales, and has sponsored rain barrel sales through contractor partnerships. The rebate program has been expanded to include rebates for large rainwater and condensate collections systems. 10
