Answer
Verdict on the wording above: Supported as of EPA observations spanning operation from 2021, 2022 connection status and early-2023 context Independent evidence supports the claim as stated, for the stated period. Not permanent; not proof of related claims. How verdicts work →
- Who stated it
- Said in US EPA case study · government record →
- What the evidence establishes
- EPA documents operation beginning June 30, 2021 and describes a city-operated treatment and recirculation system serving Microsoft's campus. Applies to the wording and period shown (EPA observations spanning operation from 2021, 2022 connection status and early-2023 context).
- Biggest limitation
- Current measured withdrawal, consumption and discharge; a reconciled explanation of Microsoft's separate 380-million-gallon estimate; and operating changes after EPA's dated observations.

Evidence
What the evidence supports
EPA documents operation beginning June 30, 2021 and describes a city-operated treatment and recirculation system serving Microsoft's campus. EPA estimates 138 million gallons per year of potable-water savings, reports about 260 million gallons per year of canal-water makeup and says potable groundwater supplies about 5% of annual makeup. These are different measures and are not additive total consumption or a current meter audit.
Still unknown
Current measured withdrawal, consumption and discharge; a reconciled explanation of Microsoft's separate 380-million-gallon estimate; and operating changes after EPA's dated observations.

What it supports Operation since 2021, reuse-system design, estimated potable-water savings and reported makeup-water figures. Not current total consumption.
Conflicting evidence
- Microsoft launch account 380 million gallon figure · company launch story · A different potable-savings estimate than EPA 138M.

Field Cooling + water
From Microsoft Quincy: Supported as delivered; combined measures and a 2021-2022 observation window
To EPA documents an operating reuse system; distinct estimates and dated observations are separated
Why The second review separated estimated savings, canal makeup and potable makeup share and removed an unsupported original-publication year.
