New Braunfels Utilities, or NBU, is about to begin work on a $7 million wastewater project in Gruene's Historic District.

About the project

The project will be carried out in two phases. It aims to provide the capacity needed to serve the area today and the ability to handle the area’s future growth, according to a news release.

Phase 1 construction focuses on replacing the aging, 12-inch sewer line along Gruene Road—from Hunter Road to the 1200 block of Gruene Road—with an 18-inch sewer line. Phase 1 construction is expected to commence in January and wrap up in March, according to the release.

The second phase of the project—dubbed River Phase—will consist of replacing old cast-iron lines near the Guadalupe River, which will prevent future pipe failures and keep the entire system running smoothly. An Odor Control Unit and siphon vault will also be installed behind businesses on the 1200 block of Gruene Road. The Odor Control Unit will eliminate occasional, unwelcome odors in the downtown Gruene area, the release states.


Phase 2 construction is slated to begin in March and wrap up in May.
