Even with a negotiated contract between the city of Conroe and the San Jacinto River Authority that secures Conroe’s access to water in Lake Conroe for up to 80 years, city officials told The Courier recently that the search for future water resources must continue.
For that reason, we welcome the decision of the Lone Star Groundwater Conservation District to give large volume groundwater users the option of looking for water source alternatives to Lake Conroe surface water.
The Lone Star Groundwater Conservation District recently approved changes to its district rules that give large volume groundwater users, those groups that pump at least 10 million gallons annually, the opportunity to look for alternative water sources in place of the multi-billion dollar surface-water project proposed by the San Jacinto River Authority.
As a result, representatives from several of the municipal utility districts located around Lake Conroe are looking at their options, particularly the potential for obtaining and treating brackish water. MUD No. 18, the water provider for Bentwater, already has advertised for a contractor to drill a test well to determine if there’s enough brackish groundwater underneath the Gulf Coast Aquifer to make a project viable. Brackish groundwater is located at greater depths than water from the aquifer and must be treated using reverse osmosis, all of which adds to the costs of the water as an alternative source.
Still, some believe brackish water could become an affordable alternative to tying into a surface water treatment and distribution system utilizing Lake Conroe surface water.
The negotiated agreements which now tie Conroe and The Woodlands to Lake Conroe’s surface water were an important step to ensuring this county has the water it needs for the future.
But the test well that MUD No. 18 plans to drill could open a door for other possibilities for water in the future. Whether brackish water is a viable option is a worthwhile question, and as Montgomery County looks to its future water needs, it’s worth answering.
