Watershed consumptive use

Basin: Lower James (HUC-8 02080205). Figures are consumptive use, not withdrawal, because evaporative data center loss is consumptive. USGS data year 2020.

CategoryConsumptive use (MGD)Share of basin
Residential 35 70.7%
Thermoelectric power 8 16.2%
Industrial 4 8.1%
Irrigation 2 4.0%
Mining 0.5 1.0%
Existing data centers 0 0.0%
Total49.5100.0%

Total is the sum of the categories listed above. Shares are each category divided by that total. Source: USGS Water Use 2020, Henrico County.

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.

Where this water is consumed: PJM Dominion zone generation is distributed across the multi-state grid; Scope 2 water occurs at upstream plants outside the local James basin.

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.

Regulatory and siting status

Richmond metro emerging market. Henrico aggressively recruiting; Dominion has capacity. Mid-Atlantic alternative to NoVA.

Sources: Water: Henrico DPU. Grid: PJM Dominion zone. Incentives: state DC tax exemption + locality grants.
