Former Dodge Village site on the Pequabuck River. CT Siting Council approved fuel-cell power (Petition 1540) in Dec 2022; a construction-time extension was approved Sept 2025; the Inland Wetlands Watercourses Agency approved the wetlands permit in April 2026 with stormwater conditions. Active local opposition over water usage — the operator has published its own water-use comparison.
Estimated water use
Estimate2,130–5,550 gal/day
3 MW × 710–1850 gal/day/MW (closed_loop_chilled_water)
3 MW capacity: graywolfdatacenters.comclosed_loop_chilled_water cooling: bristolct.gov
Ratio source: Uptime Institute Journal
Low end derived from an indirect-evaporative (ExCool-style) system reported at ~260,000 gal/year for a 1 MW facility. High end derived from a direct-evaporative system reported to use 10% of a traditional chiller/cooling-tower system's water. Both figures are this site's own gal/day/MW conversion from the cited source, not quoted verbatim.
Derived from a published industry ratio; actual use varies with operating conditions, load, and weather.

Operator discloses closed-loop cooling system
Facility described as using a closed-loop liquid cooling system (water recirculates) with municipal water purchased from Bristol Water & Sewer. Operator's own comparison: about 30% of the water used by a local grocery store and about 10% of a typical high school's annual use. Note: this and the wetlands-permit source refer to the applicant of record as "ReNew Properties LLC" / "ReNew Developers" at the same address, petition, and site as Gray Wolf Data Centers — likely the same project under a different corporate/filing name, but the discrepancy has not been independently resolved.

Drawdown story
AssessmentIs the water table's behavior near this facility consistent with its estimated draw — and how strong is the evidence? A fixed rubric, recomputed monthly; every number below is stored with the inputs that produced it. Method: attribution-v1.
1 · Pathway
The operator has not disclosed where this facility's water comes from. Until a source is published, the assessment is capped: an unclassified pathway can never raise the score.
2 · Detectability
Even at the high end of the estimate, the draw would be invisible (under 0.2 ft) at the nearest monitored well 3.2 mi away — "not detectable" is the expected outcome.
3 · Signal
No monitored well within 2 miles of this facility — there is no near-field record to compare against controls.
Facility not yet operating; baseline being recorded.
