$126M Expansion Planned for Gruene Water Reclamation Facility
The utility’s capital program would nearly double treatment capacity through an expansion of process systems, electrical equipment and site piping.
New Braunfels Utilities is planning a $126 million expansion of the Gruene Water Reclamation Facility to support continued growth. The utility’s October 2 project update, followed by October 12 reporting, describes an increase from 2.5 million to 4.9 million gallons of daily treatment capacity.
The full project budget and near-term allocation are different figures. NBU identifies $81 million budgeted over the next five years within the $126 million program. The amounts should not be added together or presented as competing estimates for the same spending period.

Expansion across the treatment process
NBU’s scope includes incoming-flow distribution, headworks, biological treatment, clarification, filtration, disinfection and solids handling, supported by electrical equipment and site piping. The expansion is a process-wide program rather than simply one additional tank.
Each treatment stage must be coordinated with the others. More capacity at the front of a plant is useful only if downstream treatment and solids management can support the additional flow. Construction planning must consider how the existing facility continues to operate while new systems are installed and brought into service.
The delivery horizon needs a current baseline
October reporting describes design at approximately 30% and an anticipated fiscal-2030 construction start, followed by roughly three years of work. Earlier January utility board material used a 2028–2031 window. These are different planning baselines; the newer reporting should not be silently combined with the older dates.
The project is a future opportunity, not a current general-contractor award. A refreshed utility schedule and procurement plan will be important before assigning firm bid, mobilization or commissioning dates. The board record identifies a proposed design appointment, detailed for members below.
What contractors should follow
The physical program points toward substantial process, civil, mechanical and electrical coordination. Potential packages include structures, piping, power distribution and treatment equipment, but package boundaries and the construction delivery method have not been established in the material reviewed.
The next steps are further design development, an updated funding program and formal procurement notices. Those will show how expansion is sequenced around ongoing operations and when the long-term capacity plan becomes an executable construction schedule.
