What happened
On 22 September 2026, City of Hendersonville staff joined representatives from the North Carolina Department of Environmental Quality, Dogwood Health Trust, Land of Sky Regional Council and other partners at the city's Wastewater Treatment Facility to celebrate the funding milestones reached on the Flood Mitigation and Expansion Project City of Hendersonville, NC (.gov). The published date of the city's own write-up is 23 September 2026 City of Hendersonville, NC (.gov).
The funding package is a mix of grants and low-interest loans that the city says will let it complete flood-hardening and capacity work while keeping rates affordable City of Hendersonville, NC (.gov). The city describes the overall program as a $100+ million project and says it is still aggressively pursuing additional funding to close the gap City of Hendersonville, NC (.gov). Utilities Director Adam Steurer tied the work directly to climate exposure and growth: "We are thrilled to receive this funding to complete improvements at the City's Wastewater Treatment Facility. The project makes our wastewater treatment facility more resilient to extreme flooding like we saw during Hurricane Helene but also provides additional treatment capacity to support the needs of our growing community" City of Hendersonville, NC (.gov).
Project scope and status
The project relocates and elevates treatment equipment away from flood-prone areas, addressing the damage caused when Hurricane Helene pushed floodwaters through the plant and left it inoperable for almost two weeks City of Hendersonville, NC (.gov). The same package raises design treatment capacity from 4.8 million gallons per day to 6.0 million gallons per day, a 25 percent uplift on the existing rating City of Hendersonville, NC (.gov). Steurer also credited the regional partners who helped secure EDA funding: "Our utility staff and partners have worked diligently to win these competitive funding awards so that we may complete important infrastructure projects while keeping our rates affordable. I'm also grateful for the regional Land of Sky Council of Governments team and the Henderson County Partnership for Economic Development who assisted Hendersonville with the EDA funding application" City of Hendersonville, NC (.gov). Mayor Pro Tem Jennifer Hensley added, "We have received millions of dollars in grants so far, and this will have a direct impact on our ratepayers and our businesses" City of Hendersonville, NC (.gov). The next milestone is closing the remaining funding gap on the $100+ million total before construction can be finished.
Specification read
In buyer units, the existing 4.8 MGD rating is about 18,170 m³/day and the new 6.0 MGD rating is about 22,710 m³/day, an increase of roughly 4,540 m³/day, with the design uplift driven entirely by the capacity numbers reported by the city City of Hendersonville, NC (.gov). For a Municipal plant in this flow class serving a mid-size Carolina mountain community, the standard treatment train is screening and grit removal, primary clarification, biological treatment (typically an A2O or MBBR configuration, with MBR used where effluent limits or footprint drive selection), followed by tertiary filtration and UV or chlorine disinfection, and the Hendersonville scope lands squarely on the biological and disinfection stages, with the headline change being relocation and elevation of equipment above the flood line City of Hendersonville, NC (.gov). If your plant is in the 15,000–25,000 m³/day range, draws from a combined sewer area or a flood plain, and is under consent-decree or growth-driven pressure to add 20–30 percent hydraulic capacity while also hardening critical infrastructure, the practical read is that the procurement focus here is flood-resilient mechanical equipment, structural elevation of basins, and biological-stage expansion rather than a wholesale change of treatment process. Comparable buyer guidance on biological-stage selection is covered in MBR vs Conventional Activated Sludge for Transportation Equipment Wastewater in Sumner, WA (2026 Engineering Guide) and MBR vs Conventional Activated Sludge for Transportation Equipment Wastewater in Laurel (2026 Guide).
FAQ
What capacity will the Hendersonville plant have after the project?
The plant will move from 4.8 million gallons per day to 6.0 million gallons per day, a 25 percent increase, as reported by the City of Hendersonville City of Hendersonville, NC (.gov). In metric terms that is roughly 18,170 m³/day rising to about 22,710 m³/day.
How big is the funding gap and what is the procurement signal?
The city describes a total project of more than $100 million and says it is still pursuing additional grants and loans, with the current package combining grants and low-interest loans City of Hendersonville, NC (.gov). For suppliers, that signals staged bid opportunities tied to flood-hardening, equipment elevation and biological-stage expansion rather than a single lump-sum award.
Why is the project tied to Hurricane Helene?
Floodwaters during Hurricane Helene damaged equipment and left the facility inoperable for almost two weeks, which is why the project relocates and elevates treatment equipment above flood-prone areas City of Hendersonville, NC (.gov). Plants in similar flood-exposed basins should expect funders and insurers to weight elevation and resilience as heavily as raw capacity.
What is the typical lead time for a 20–25 percent capacity expansion at a municipal plant?
For a Municipal biological-stage expansion in the 15,000–25,000 m³/day class, detailed engineering, permitting and construction commonly run 24 to 36 months from notice to proceed, with biological equipment delivery often the long pole (general industry range, not from the sources).
