{"generated":"2026-09-15T02:39:49Z","source":"US EPA Enforcement and Compliance History Online \u2014 Clean Water Act permitted facilities reporting sector code 518210 (data processing and hosting)","counts":{"permits":43,"geolocated":43,"with_reported_flow":7,"total_reported_flow_mgd":2.57,"states_queried":52,"states_failed":0},"unit_note":"Flows are million gallons per day, as EPA publishes them. A blank flow is a blank field on the permit, not a measured zero.","plain":"Discharging water to a river or the sea in the United States requires a permit, and permits are public. This is every facility that holds one and describes itself as a data centre: where it is, its permit number, and the flow the permit records. It is the difference between guessing an effect from a thermometer downstream and reading the document that authorises the discharge.","caveats":["A floor, not an inventory. Only facilities that report the data-centre sector code appear. A campus permitted under a parent company's or a landlord's code is invisible here, and there is no way to count how many that hides.","A permit authorises a discharge; it does not measure one. The flow fields are what the permit records, not a meter reading taken today.","Most of a data centre's cooling water leaves as vapour into the air, not as water into a channel. A site with no discharge permit is not a site that uses no water \u2014 it is usually a site whose water goes to the sky and to the sewer.","United States only. Other countries permit discharge too, under registers WAPR has not yet read, so the rest of the world is blind here rather than clean.","Nothing here says what the receiving water does in response. That is a separate question, and the honest answer for heat is in the thermal ceiling: the effect is far below what any instrument downstream could attribute to a campus."],"permits":[{"name":"JASMINE
