NBU's capital plan would double McKenzie's biological nutrient removal treatment capacity to 5 million gallons a day, with $10.1 million projected for FY2027.
The plan lists McKenzie's existing biological nutrient removal treatment capacity at 2.5 million gallons per day. If completed as planned, the expansion would raise that treatment capacity to 5 million gallons per day for the wastewater system. Those are capacity figures, not measurements of how much wastewater reaches the plant today.

What the expansion costs
A Comal.News extraction of NBU's McKenzie project page lists more than $10 million in projected FY2027 spending. It lists the same amount for the full FY2027–FY2031 project window. In other words, the plan places all the spending it forecasts for this project in FY2027; it does not establish what NBU has spent or finished since the plan was prepared.
| Category | Projected amount |
|---|---|
| Contract labor | $7,867,640 |
| Contract engineering | $1,318,460 |
| Overhead | $675,685 |
| Internal labor | $270,199 |
| Total | $10,131,984 |
Comal.News extracted these figures from NBU's project page. NBU notes that its figures are independently rounded.
Contract labor is the largest listed category at nearly $8 million. The work described goes beyond one treatment tank: NBU plans new treatment basins and clarifiers, along with expanded filtration, digestion, electrical, piping and site systems. The project description makes headworks, UV disinfection and solids dewatering contingent on further evaluation.
