NBU plans $81 million for Gruene wastewater expansion through 2031

NBU plans to expand Gruene wastewater treatment capacity to 4.9 million gallons a day. The five-year plan costs $81 million, targets completion in 2032 and leaves later spending subject to future review.

A Comal.News count of New Braunfels Utilities’ capital plan puts $81,000,088 in projected FY2027–FY2031 spending toward the Gruene Water Reclamation Facility expansion. Most of that five-year amount is scheduled for FY2030 and FY2031, making the timing as important as the total.

The proposed expansion would raise Gruene’s permitted wastewater treatment capacity to 4.9 million gallons a day, with completion projected for July 31, 2032. That is the capacity and completion target in NBU’s project entry, rather than a statement that construction or a permit change has already been completed.

From the source record

Selected annual amounts from NBU’s FY2027–FY2031 Gruene expansion plan.FY2027 is the adopted capital budget; the later years are planning estimates.

When the plan schedules the spending

The plan schedules more than $4 million in FY2027, about $2.94 million in FY2028, about $1.1 million in FY2029, about $31.57 million in FY2030 and about $41.06 million in FY2031. Those figures come from the project figures; the table gives the exact annual amounts.

Planned Gruene facility expansion spending by fiscal year, FY2027–FY2031
Fiscal yearPlanned spending
FY2027$4,334,475
FY2028$2,935,680
FY2029$1,098,608
FY2030$31,567,008
FY2031$41,064,317
Five-year total$81,000,088

Amounts are from NBU’s Gruene project entry. The five-year total is a Comal.News sum.

What the budget does and does not settle

NBU’s plan lists FY2027 as an adopted capital budget, while FY2028 through FY2031 are planning estimates subject to annual review and future board action. Readers should therefore treat the five-year total as a project plan, not a single authorization to spend the entire amount now. The plan also says future rate adjustments require board approval.

The project entry identifies Gruene as a wastewater treatment capacity expansion. It is a separate line of work from the McKenzie capacity project and the Kuehler rehabilitation listed elsewhere in the capital plan; their figures should not be added to Gruene’s total.

What to watch next

The next NBU capital budget and any Gruene-specific board action will show whether the later estimates become authorized spending. The project entry gives readers a starting point for tracking the capacity target and annual amounts as those records appear.
