As New Braunfels and the NBU service territory continue to experience unprecedented growth, NBU has committed to more than $688 million in 145 capital improvement projects from FY2022 to FY2026. These improvement projects will ensure we are well prepared to meet the electric, water, and wastewater needs of our customers for decades to come.

Below you can find information about existing projects and any road closures or impacts resulting from their construction.

Castell Avenue 24-inch Water Line Project

This project will provide an additional 24-inch transmission mainline needed to send water from downtown New Braunfels to the County Line ground storage tank and surrounding areas and replace aging water and sewer lines. The project was separated into two bid packages, East and West.

No weekend work will be allowed in the downtown areas and sidewalks are to remain open, to the extent possible, for pedestrian traffic. Service connections from the water and wastewater lines to each individual business will be completed between Monday and Thursday, 2:00 a.m. – 6:00 a.m. to minimize impacts of service outages.

Work on the West portion of the project began in April 2021 and was substantially completed in June 2022.


Work on the East portion of the project began in May 2021 with an estimated completion date of February 2023, weather permitting.

FM 306 Pump Station Expansion and Discharge Line

This nearly $9.5 million project includes the installation of a 3.5 MGD pumping capacity expansion at the existing FM 306 Pump Station and a new 36-inch water line replacing the existing 18-inch water line. The project will also include a new 24-inch line replacing the existing 12-inch line along FM 306 from the FM 306 Pump Station site, down Goodwin Lane to the intersection of Goodwin Lane and Pebble Creek Run. The project will improve the capacity to serve future growth in the Kohlenburg Pressure Zone.

Work on this project began in January 2022 and is expected to be completed in May 2023. The water line realignment will require roadways to be closed to thru-traffic.

Grandview Pump Station and Discharge Line Upgrade Project

This nearly $5.5 million project is just one of 77 water/sewer projects that NBU has planned to keep improving its system and is part of our master plan to help ensure that residents and businesses in New Braunfels continue to have reliable access to water for decades to come.

This project includes capacity upgrades to NBU’s Well #4 facility at the end of Beverly Lane, the installation of a larger pipeline from Well #4 to the Grandview Pump Station, and the installation of a larger pipeline from the Kerlick/Walnut intersection to the other side of Loop 337. The section of pipeline between Grandview and Kerlick Lane was upsized when TxDOT widened Walnut Avenue with the “Up the Hill” Project several years ago. Overall, this grouping of projects will increase water production capacity (Well #4), pumping and storage capacity (Grandview), and transmission capacity (the pipelines) to bring water from NBU’s lowest and largest pressure zone where the majority of water is produced, the Downtown Zone, to the Kerlick Zone, which serves a significant portion of NBU’s water system from the Kerlick/Mission neighborhood to State Highway 46 Newks and half of Veramendi areas.

New Braunfels Utilities and the contractor are working to ensure no roads will be closed with the planned work outlined below; just the sidewalk and part of the right turn lane from State Highway 46 to the HEB driveway, off of the Loop 337 Frontage Road. We are planning to keep at least two of the three lanes of traffic open on Walnut Avenue at all times. Additionally, Kerlick Lane is an important road to keep open, and the contractor will work to address any anticipated changes as early as possible.

Work on this project began in May 2022 with an estimated completion date of December 2022, weather permitting.

Fall 2022

McQueeney Road 24-inch Water Line Project

The project is one of 145 Capital Improvement Projects slated over the next five years and budgeted at nearly $3.9 M. This project will upgrade existing infrastructure by replacing a 12-inch water line along McQueeney Road from County Line Road to the County Line Memorial Trail with 18-inch and 24-inch gravity mains. These improvements will provide reliability in service and additional capacity for future growth in the area. The project began in June 2021.

Scheduled Traffic Impacts

Schedules are subject to change.

McQueeney Road between Trade Center Drive and IH-35 southbound frontage road will remain closed through Fall 2022, to allow New Braunfels Utilities’ contracted crews to install a bore pit for water infrastructure under IH-35 in the westbound lanes of McQueeney Road. The closures are clearly marked and detour signs will guide traffic around closures.

  • Intersection of McQueeney Road and Executive Drive – 11.29.2022 to 12.02.2022, daily closure from 7:00 a.m. to 5:00 p.m. with flagging operations in place.

Surface Water Treatment Plant 24-inch and 30-inch Discharge and Water Line Project

This project will provide additional transmission capacity to deliver clean, high-quality drinking water to our community now and decades into the future. When completed, the project will help to alleviate high-pressure issues in the area when the Headwaters at the Comal, the Surface Water Treatment Plant (SWTP), and Landa Park pumps are running simultaneously.         

The work will cover approximately 2.5 miles, constructing approximately 12,800 linear feet of 24-inch and 30-inch water main. Work will include trenching/backfill, trench safety, curved micro-tunneling, jacking/boring, fittings, valves, and connections, generally from the Surface Water Treatment Plant located on Gruene Road to the 306 Pump Station located at 2320 East Common Street. Much of the work will be done along Rivercrest Drive, Gruene Road, and Waterway Lane.

This project will connect and provide transmission capacity to support NBU’s Landa Park pump station expansion and dovetail into the planned Surface Water Treatment Plant expansion project.

Scheduled Traffic Impacts

Vehicular traffic should expect delays, varying lane conditions, and flaggers directing traffic. Access to homes and businesses will be maintained for the duration of construction.

Schedules are subject to change.

Work on this project began in February 2022 with an estimated completion date in spring of 2023, weather permitting.
