North Texas may be shopping for water out of state, and the numbers behind that conversation are worth understanding.
The North Texas Municipal Water District, which supplies McKinney, Allen, Frisco, Plano, Richardson, Princeton and nine other member cities serving more than 2.4 million people, announced Oct. 28 that it is open to exploring a purchase of surplus water from Millwood Lake in southwest Arkansas. A private company, Heartland Water Partners, approached the district about it. In an Oct. 27 letter, Executive Director Jenna Covington said formal negotiations could open "in the near future," while noting only informal talks have happened and no contract terms exist yet.
The board actually moved first, on Oct. 22. Resolution No. 26-46 lets the executive director pursue surface water that is underused, affordable for ratepayers, located in Texas or a neighboring state, and large and dependable enough to justify new raw-water lines built to last 50 years or more. It approves no purchase and requested no money.
Here is the demand side: the district cites the Texas State Water Plan in saying it must find more than 400,000 acre-feet of additional supply by 2080, a planning horizon in which its service-area population is projected to almost double. Conservation and reuse already make up upward of 30 percent of what it delivers.
The supply side sits with Texarkana, Arkansas, which holds roughly 150 million gallons per day of Millwood Lake rights, about 21 times what it currently uses. Its board voted 6-0 on Oct. 13 to apply to send as much as 110 million gallons per day to Texas, and a sale has been described as worth $16 million to $20 million a year to that city.
Nothing moves quickly from here. The Arkansas Natural Resources Commission meets Nov. 18, the Arkansas legislature convenes Jan. 11, and both would have to approve a cross-state transfer. A final sale contract would need its own vote.
For anyone tracking land in the district's service area, the takeaway is about sequencing. Tap capacity is the question developers ask cities, but raw supply is the question cities have to answer first, decades ahead. A feasibility study is not water and a resolution is not a purchase, but both mark the early stage of how a region prices its next fifty years of growth.
