Editorial review 2026-09-12 · Jurisdiction: Sweden — Environmental Code chapter 11 and the water-operations ordinance
Water rights and abstraction — reading a Swedish water file
Is the cooling loop a water operation under chapter 11 of the Environmental Code, a municipal water-and-sewer conversation, or only a WUE slide? Sveriges Domstolar’s water-operations page states the main rule: larger water operations need a permit from the land and environment court, under chapter 11 of the Environmental Code and the Act (1998:812) with special provisions on water operations. Chapter 11, section 9 a lets certain smaller operations be notified instead. Havs- och vattenmyndigheten’s notification page, last reviewed 5 April 2018 on that page, says an activity may start at the earliest eight weeks after the notification has been made to the county administrative board, that a notification under 11:9 a does not have legal force (rättskraft), that it does not bind private interests, and that it does not protect the operator from later supervision. Ordinance (1998:1388) as later amended then ties start to a screening decision that significant environmental effect is not assumed. Ordinance (1998:1388) section 19 lists the notification classes, including leading away at most 600 cubic metres of surface water per day from a watercourse, though at most 100 000 cubic metres per year, or at most 1 000 cubic metres per day from another water area, though at most 200 000 cubic metres per year. Those are statutory notification categories. They are not a data-center water permit and not a WUE. The WUE page keeps Green Grid, ISO and Union reporting in their own cells. This page keeps the legal water object.

General orientation. Assess the specific project separately. Applies to: Readers testing a water-right, abstraction or “water-free hall” sentence on a Swedish plot.
Reading order
Name the water object before you name a permit. Make-up water, humidification, evaporative rejection, a once-through loop, seawater, a municipal potable network and no on-site water are different objects. The WUE page already asks for that row. This page asks which Swedish legal file, if any, the object opens.
Then name the counterpart. A county administrative board handling a chapter 11 notification, a land and environment court handling a permit, a municipal environmental office, and a municipal water-and-sewer company are four desks. Sveriges Domstolar’s page says the county administrative board is usually the supervisory authority. Havs- och vattenmyndigheten publishes the notification guidance used on this page. A commercial heat discussion with a district-heating company is a fifth desk. Do not collapse them into “water approved.”
Then label the paper. A design litre is not a measured year. A notification is not a permit. A permit has legal force against those who were parties; a notification, HaV says, does not. A WUE cell does not classify the activity.
- Water object before the legal label.
- Court, county board, municipality, VA company, heat company.
- Notification versus permit versus WUE.
- Statutory cubic metres stay on the ordinance page.
What the water file actually changes
Sveriges Domstolar’s page is the cleanest main-rule sentence in this register: larger water operations need a permit from the land and environment court. The court also records that the supervisory authority — usually the county administrative board — may, in an individual case, order the operator to apply for a permit, and that Natura 2000 can open a separate permit under chapter 7, section 28 a. Those are mechanism sentences. They are not a classification of your hall.
Ordinance (1998:1388) section 19 is the dated list of operations that, instead of the chapter 11, section 9 permit duty, must be notified before they start. The list includes wetlands up to 5 hectares, fill or piling up to 500 square metres in a watercourse or 3 000 square metres in another water area, and the two surface-water abstraction classes already named in the lede. Section 20 says the notification shall be written and shall contain the particulars, drawings, maps and technical descriptions the authority needs. Section 22 a, as later amended, requires a decision on whether the activity is assumed to have a significant environmental effect. Section 22 c says that decision shall be taken as soon as possible and at the latest eight weeks from the notification day, unless the time is extended. Section 22 e then says a notifiable water operation may start at the earliest after the authority has decided that significant environmental effect is not assumed. HaV’s page, last reviewed 5 April 2018 on that page, still writes the older start sentence — at the earliest eight weeks after notification to the county board — and records that the courts have in several cases held that an action cannot be notified after the fact. Keep those two clocks in different cells: HaV’s 2018-reviewed sentence, and the later ordinance text.
A municipal potable or sewer connection is a different file. It sits with the water-and-sewer company and with the Public Water Services Act where that Act applies. It does not replace a chapter 11 paper if the activity is a water operation. Heat reuse is a third file. GleSYS’s 1 October 2020 Falkenberg notice is a heat-delivery start, not a water-permit decision. Digital Realty’s STO1 “cooling-free” seawater sentence is still a water object. Meta’s Luleå outdoor-air page does not publish a water permit.
The WUE page already warns that site WUE, source WUE and Union W IN / E IT are different cells. This page will not reprint those formulae as a Swedish abstraction licence.
What named primary sources show
The Environmental Code, Ordinance (1998:1388), Sveriges Domstolar and Havs- och vattenmyndigheten are the official Swedish legal sources on this page. Naturvårdsverket’s Environmental Code hub remains the national starting vocabulary. None of those pages, in the files used here, classifies a named Swedish data-center hall as a notified or permitted water operation.
Operator pages stay operator pages. Digital Realty STO1 names remote seawater cooling and “cooling-free” operation for over half the year. Seawater is still water. STACK’s STO01 page and atNorth SWE01 do not, on the cited pages, publish a water-permit decision. GleSYS’s 2020 heat notice is a heat start. Meta’s Luleå page describes outdoor air and local hydropower. Hydropower in the fuel mix is not a cooling-loop licence.
If the primary material is silent about intake, discharge, notification or permit, the cell stays open. “Research incomplete” and “not publicly disclosed” remain different statuses.
A matrix instead of a water-free badge
Draw one page with legal states in rows and water objects in columns. No chapter 11 paper, a notification, a court permit, a municipal VA contract and a heat contract are different rows. Outdoor air, evaporative make-up, seawater and a municipal network are different columns. Empty cells stay empty. A WUE slide is not a column.
Do not invent a Swedish abstraction league table from the ordinance’s 600 cubic-metre class, from Digital Realty’s seawater sentence or from the IEA’s US litre example on the WUE page.
| Legal state | What a source can show | What this page will not invent |
|---|---|---|
| Permit at the court | Domstol: larger water operations, chapter 11 | A named Swedish hall permit |
| Notification | Ordinance 19 § classes; HaV: eight weeks, no rättskraft | A data-center water licence |
| Municipal VA | A utility capacity reply | A chapter 11 classification |
| WUE cell | Green Grid / ISO / Union reporting on the WUE page | An abstraction permit from a climate slogan |
Common misreads
The first misread is to treat a Nordic winter as a water right. The second is to treat a municipal VA conversation as a chapter 11 paper. The third is to treat a notification as a permit with rättskraft.
The fourth is to paste the ordinance’s 600 or 1 000 cubic-metre classes onto a hall without asking the competent authority whether the activity is in those classes. The fifth is to treat “cooling-free” or outdoor air as proof that no water file exists. The sixth is to use hydropower in Luleå as a cooling-loop licence.
What to ask next
Ask for the water object, the annual and peak volumes, the source and the discharge or evaporation path. Ask the competent authority — with those figures attached — whether the activity is a water operation, a notification class, a permit class, or none of those. Ask whether a municipal VA contract is a separate paper.
Then open the WUE page, the water-and-cooling approvals page and the cooling page. If the operator will not name the litre or the legal paper, record the gap. Do not fill it from a climate slogan or from an ordinance row copied without a classification.
- Water object, source, annual and peak volumes.
- Desk: court, county board, VA company, heat company.
- Paper: none, notification, permit, VA contract.
- Ordinance classes kept as ordinance classes.
- No invented hall water licence.
What this does and does not prove
This page proves that Swedish water rights are a chapter 11 classification exercise, not a climate slogan and not a WUE. It proves that Sveriges Domstolar publish a main-rule court permit, that Ordinance (1998:1388) publishes a notification list and a later-amended screening clock, and that HaV’s 2018-reviewed page still writes an older eight-week start sentence.
It does not prove that every Swedish hall is a water operation. It does not publish a named hall permit or a national litre. It does not treat seawater wording or outdoor air as a closed file.
Unknown loops and unknown papers stay unknown. Point to the named source gap. Until a later primary source adds a dated Swedish hall notification or permit, the legal cell stays empty.
