New Braunfels Utilities is on track to begin work on its Surface Water Treatment Plant capital improvement project this month, according to a press release.

The $11.5 million water line project will provide additional transmission capacity to deliver drinking water to residents and to alleviate high-pressure issues that occur when the Headwaters at the Comal, the Surface Water Treatment Plant and Landa Park pumps are running simultaneously.

Beginning March 21, a portion of Gruene Road between Hanz Drive and Rivercrest Drive will experience all-day lane and road closures through March 30, according to the release.

The section of Gruene Road between Gruene Leaf Drive and Gruene Lake Drive will be subject to closures March 30-April 8.

Both closures will allow NBU crews to install bores in preparation for waterline installation, according to the release.


The expansion project is scheduled for completion in spring 2023 and will add an additional 8 million gallons per day, according to NBU.
