A public teleconference hearing is scheduled for May 26, 2020 to receive comments regarding the adopted 2021 Region C Initially Prepared Plan. The current state water planning process has been in place since the 751" Texas Legislature passed Senate Bill One in 1997 and is administered by the Texas Water Development Board (TWDB). The Texas State Water Plan goal is to ensure that Texas has an adequate water supply in times of severe drought. The plan is updated every five years, with the last update occurring in 2017. To facilitate preparation of the plan, Texas is broken into 16 different planning areas by the TWDB. Fort Worth resides within Region C, which includes the majority of the upper Trinity River basin and all or part of 16 North Central Texas counties. Engineering consultants are retained by the planning groups in order to prepare the regional water plan, with costs associated with this work funded by the TWDB. The Region C Planning Group consists of 22 voting members representing agriculture, counties, electricity, environmental, groundwater, industry, municipalities, water districts/utilities, river authorities, and the public. Regional plans from the 16 different planning groups are compiled into the State Water Plan by the TWDB. The regional plan must follow the format and content requirements dictated by the TWDB. The regional plan documents existing and historical population, water usage and water supplies by individual entities, user groups, and jurisdictions, including an analysis on historical growth and use trends. Population and water usage projections and associated water supply needs are developed for a 50-year planning cycle. Specific water supply and management strategies are identified, including the associated project costs and required in-service dates. Examples of water supply and management strategies include conservation, direct and indirect reuse, new reservoirs, desalination, aquifer storage and recovery, and transmission and distribution projects required to move existing supplies to the user. The plan presents planning level analysis only, with the anticipation that detailed engineering analysis, study, permitting and design would follow in the implementation of any recommended supply and management strategy. Water supply strategies for the City of Fort Worth Utility outlined in the plan include continued implementation of water conservation practices and tools to further reduce water usage, utilization of drought management measures to curtail water usage in times of drought, direct reuse projects at Village Creek, Mary's Creek, and the TRA Denton Creek Water Reclamation Facilities, expansion of the Westside, Eagle Mountain, and Rolling Hills Water Treatment Plants, and additional supply from the Tarrant Regional Water District (TRWD). The cost estimate for the various recommended strategies (which excludes the cost of additional supply from TRWD) over the 50-year planning period is estimated at $2.67 billion dollars. Of the strategies listed, conservation and reuse account for 31% of Fort Worth's (and TRWD's) future source of water supply.

Water supply strategies for the TRWD outlined in the plan include continued implementation of water conservation practices, an aquifer storage and recovery pilot project, additional transmission capacity to convey Richland Chambers reuse water, construction of the Cedar Creek wetland and TRA reuse water project, construction of the Tehuacana water supply reservoir in Freestone County, development of groundwater from the Carrizo-Wilcox aquifer in Freestone and Anderson Counties, TRWD portion of the joint strategy (with North Texas Municipal Water District (NTMWD) and Upper Trinity Regional Water District (UTRWD)) for construction of the Marvin Nichols Reservoir, TRWD portion of a joint strategy (with NTMWD and UTRWD) to increase available water supply from Lake Wright Patman, and additional transmission pipelines necessary to convey the new water supplies to the customer base, the majority of which is located in Tarrant County. The cost estimate for the various recommended strategies over the 50-year planning period is estimated at 6.3 billion dollars.
