NTMWD Long Range Water Supply Plan
The population of the NTMWD service area is expected to more than double between the years 2010 and 2060 from 1.6 million to an estimated 3.8 million served. To meet the treated drinking water needs of the service area through 2060, the NTMWD has identified numerous water management strategies and projects to generate additional water supplies. These strategies include: using current supplies, connecting to existing supplies, developing new reservoirs, and making use of supplies from conservation and reuse strategies. More than 25 percent of the total future supplies are estimated to consist of conservation and reuse water strategies.
Conservation is by far the most economical water supply strategy identified when compared to all other strategies. It is imperative to recognize that even if target conservation and reuse goals are successfully met, allowing the NTMWD to extend current water supplies, these strategies alone will not be sufficient to support the expected rapid growth of the NTMWD service area.
The NTMWD holds water rights in Lavon Lake for 118,000 acre-feet/year. It is anticipated that to serve future needs through 2060, the NTMWD will need to add an additional source of raw water supply equal to the capacity of Lavon Lake (118,000 acre-feet/year) every decade for the next five decades. The NTMWD has secured additional raw water supplies to meet the projected growth through approximately 2020. These additional sources include the completion of the Wetland, which can provide an ultimate capacity of 102,000 acre-feet/year, and the additional supplies obtained through a contract with the SRA for 50,000- 80,000 acre-feet/year from Lake Tawakoni
The NTMWD has commenced the permitting process for the proposed Lower Bois d’Arc Creek Reservoir, which will provide a total of 123,000 acre-feet/year of future raw water supplies including treatment and distribution to parts of Fannin County. The reservoir will also supplement supply for other NTMWD Member Cities and Customers, and will provide an added benefit of recreational opportunities such as boating and fishing. Reservoir planning, permit applications, and environmental studies have been initiated, and construction of the proposed reservoir is tentatively scheduled for completion by 2017.
