Potential advantage if demonstrated
A system that materially reduces outside water demand could reduce one of the major infrastructure pressures associated with large industrial and data-center projects.
Project River: Water & Cooling
Project-specific evidence and unresolved questions about water supply, water recovery, cooling, wastewater, stormwater, and watershed effects.
A closed loop still needs a complete water balance.
What the project says
Developer Statement
Routine operations will not depend on city waterProject River says biomass drying recovers water for process use and cooling, and that normal operations will not draw from the Hiwassee River or residential wells.
R13
Developer Statement
Closed-loop chilled waterAzure Engineering says closed-loop cooling and reverse-osmosis systems will eliminate water demand, with dryer condensing systems supplying makeup water.
R17
Developer Statement
Proposed PUD conditionsThe project says proposed PUD 77 would require 90% of process water to be generated onsite, excluding initial priming, and would prohibit a direct Hiwassee River connection.

Key unresolved operating scenarios
- ?Gas-only first phase: If power generation begins before biomass drying is operating, what supplies cooling and process water?
- ?Initial priming: How much water is required to fill the closed-loop system, and from what source?
- ?Dry fuel / seasonal variability: How does recovered-water output change with biomass moisture content?
- ?Biomass outage: What happens during days or weeks when dryers are offline?
- ?Alternate end user: How would a different industrial customer change cooling, process-water, and wastewater demand?
- ?Fire protection and emergencies: What water reserve is required independently of normal process water?
Evidence needed
Integrated water balance
Normal, peak, startup, outage, drought, and expansion scenarios by project phase.
Cooling-system design basis
Heat loads, equipment specifications, circulation rate, treatment losses, blowdown, and makeup-water assumptions.
Source and discharge documents
Utility agreements, wells or other sources, wastewater pathways, stormwater plans, and any permit applications.
Comparable operating references
Owner-verified data from facilities using the same water-recovery and cooling configuration at relevant scale.
Potential risk if assumptions fail
If recovered water is lower than expected, or unavailable during a project phase or outage, substantial supplemental water infrastructure could become necessary.
What Placeward would verify
Not whether the concept is theoretically possible, but whether the actual design produces enough usable water under realistic site conditions, with enforceable operating limits and contingency plans.
Watershed and site questions
- What streams, wetlands, floodplains, groundwater receptors, and private wells are near the final grading footprint?
- How will construction stormwater, erosion, spills, and treatment residuals be controlled?
- Will any wastewater, cooling blowdown, or treatment reject stream leave the closed process loop?
- What monitoring is required before, during, and after construction?
Permitting
TDEC water permitting and public-comment processes are separate from city annexation and zoning. The case file does not assume that any specific Project River water permit has been issued merely because a permit type could apply.
Related outside analysis
The Southern Environmental Law Center has challenged aspects of the project’s water and biomass claims in a Sept. 18 letter to city officials. Placeward treats SELC’s statements as third-party legal and technical analysis, not as agency findings. The questions raised should be tested against the full engineering review and permit-grade documentation.
