NBU plans $70.85 million Kuehler rebuild; $27.98 million is appropriated

NBU plans to rebuild equipment at both Kuehler wastewater plants through 2029. It has appropriated the first $27.98 million; future budgets will decide the rest, and customers cannot yet translate the project total into a bill change.

NBU’s Kuehler wastewater rebuild carries a $70.85 million three-year plan, but only its first $27.98 million is appropriated.

For wastewater customers, the plan funds work on treatment equipment at the existing North and South Kuehler plants. The figures come from a Comal.News extraction of project 3-C21NSRHB in NBU’s capital improvement plan. NBU’s FY2027 capital budget was approved June 25, 2026; later years in the plan remain estimates subject to future approval.

From the source record

Three annual allocations for NBU project 3-C21NSRHB in the FY2027–2031 capital improvement plan.Comal.News extraction of NBU’s capital plan, project 3-C21NSRHB, PDF page 50.

What the rebuild covers

The plan concerns rehabilitation at the existing North and South Kuehler wastewater plants. It specifies work on aeration, electrical, digester screens and membranes, non-potable water and chemical-feed systems at both sites. The North plant’s list also includes headworks and a flow meter; the South plant’s includes basin gates and blower work. These are equipment repairs and replacements at operating treatment sites, rather than a stated increase in treatment capacity.

Three years of allocations

The annual amounts below add to $70,852,207 in the project schedule. FY2027 is the appropriated year. The other two columns of the plan describe future allocations, so the full total is a plan for work through FY2029, not spending already authorized in full.

What the total says about bills

NBU says rates and other utility revenue support its capital costs. That does not turn this project total into a charge for an individual household. A bill-level estimate would require the share assigned to wastewater rates, how the work is financed and the period over which customers repay it. The spending plan establishes the scale and schedule of the proposed work; it does not establish an individual customer’s cost.

The next number to watch

The FY2028 and FY2029 estimates require future budget approval. NBU lists July 31, 2029, as the planned completion date for the Kuehler rehabilitation. The next approved capital budget and updated project schedule will show whether those later allocations hold. Readers can compare that decision with the current Kuehler project schedule in NBU’s FY2027–2031 plan.
