Umatilla County, OR (Hermiston / Boardman): Data Center Water Impact
Reference data for evaluating a data center proposal in Umatilla County, OR (Hermiston / Boardman). Every figure below is a stored value with its primary source attached. Facility-scale results are produced by the assessment tool.
Water supply
| Metric | Value | Source / basis |
|---|---|---|
| Water utility | Umatilla County / Hermiston PW | Utility of record |
| Supply source | Columbia River + Umatilla | Utility of record |
| Treatment capacity | 20 MGD | Water stress: WRI Aqueduct 4.0, HUC-8 17070103. |
| Water rate | $4.00 / 1,000 gal | Umatilla County / Hermiston PW published rate schedule |
| Watershed stress | Low (1.8 / 5) | Water stress: WRI Aqueduct 4.0, HUC-8 17070103. |
Watershed consumptive use
Basin: Umatilla (HUC-8 17070103). Figures are consumptive use, not withdrawal, because evaporative data center loss is consumptive. USGS data year 2020.
| Category | Consumptive use (MGD) | Share of basin |
|---|---|---|
| Residential | 8 | 3.6% |
| Thermoelectric power | 1 | 0.4% |
| Industrial | 15 | 6.7% |
| Irrigation | 180 | 81.0% |
| Mining | 0.3 | 0.1% |
| Existing data centers | 18 | 8.1% |
| Total | 222.3 | 100.0% |
Total is the sum of the categories listed above. Shares are each category divided by that total. Source: USGS Water Use 2020, Umatilla County. Existing DC: AWS Hermiston/Umatilla cluster.
Grid generation water (Scope 2)
Generating the electricity a data center consumes evaporates water at the power plant. That volume is real, it is attributable, and it is excluded from most corporate "water positive" accounting. On a thermal grid it is frequently comparable to the facility's own cooling water.
| Metric | Value | Source / basis |
|---|---|---|
| Grid region | BPA / Northwest | BPA |
| Electric utility | PacifiCorp / BPA | Utility of record |
| Grid water intensity | 0.1 gal / kWh | Macknick et al. 2012 × BPA hydro mix. |
| Local peak demand | 850 MW | BPA |
| Modeled rate impact | 4% to 9% | See methodology |
Where this water is consumed: BPA hydro mostly Columbia mainstem; some thermo from PacifiCorp regionally. Reservoir-evaporation attribution conservative.

Reducing the footprint here
A high stress reading is a design constraint, not a verdict. Closed-loop and dry or hybrid cooling, adiabatic assist, immersion, and reclaimed or non-potable sourcing each move the direct number, and siting against a cleaner grid mix moves the indirect number. The solutions catalog lists each option with its water reduction, its energy and cost tradeoff, and its source.
