Editorial review 2026-09-12 · Jurisdiction: Sweden — Environmental Code chapters 9 and 11 as explained by HaV; municipal water law kept separate

Water rights versus cooling take — a closed loop is not a chapter-11 take

Does the cooling plant take water in the Environmental Code sense, or have you only been handed a “water-free” slide? Havs- och vattenmyndigheten’s water-abstraction page, published 14 February 2014 and last reviewed on that page on 24 March 2022, says that “leading water away” in chapter 11, section 3 of the Environmental Code includes process water and water used to extract heat or cooling. If the water is returned to the same water area, the leading-away is a water operation under chapter 11, while the return sits under chapter 9. The same page then draws the closed-loop line: where no water is led away and a coolant circulates in a collector to a heat pump, the system sits under chapter 9 only. That is a legal classification of a loop. It is not a measured evaporative litre, not a municipal drinking-water meter and not a WUE. Chapter 11, section 5 also calls leading water away for water supply, heat extraction or irrigation a vattentäkt. The water-rights page already owns the permit-versus-notification clock and the cubic-metre classes in Ordinance (1998:1388) section 19. This page only asks which published water object the cooling take is actually sitting on.

General orientation. Assess the specific project separately. Applies to: Readers testing a water-right, cooling-take or “closed-loop, therefore no water file” sentence on a Swedish plot.

Reading order

Name the loop before you name the right. An open once-through take from a watercourse or another water area, an open take that returns to the same water area, a closed collector with coolant, evaporative make-up from a municipal network, and no on-site water are different objects. HaV’s page says an open surface-water take to a heat pump is a water operation. A closed collector is chapter 9 only. Do not paste either sentence onto a municipal drinking-water tap.

Then name the counterpart. A land and environment court handling a chapter 11 permit, a county administrative board handling a notification, a municipal environmental office handling chapter 9 environmentally hazardous activity, and a municipal water-and-sewer company under the Public Water Services Act are four desks. The water-rights page already refuses to collapse them. This page adds the cooling question: which desk, if any, the heat or cooling extraction actually opens.

Then keep the physical take on its own row. A legal right to lead water away is not a measured cubic metre. A WUE cell is a Green Grid or ISO intensity, not a classification under chapter 11. A discharge or evaporative file sits on the discharge-permits page. Shoreline protection sits on the strandskydd page. Empty cells stay empty.

  • Open, returned or closed loop before a water-right slogan.
  • Court, county board, environmental office or VA company.
  • Legal right ≠ measured cooling take ≠ WUE.
  • The water-rights page already owns the cubic-metre classes.

What a right measures and what a take measures

HaV’s 2022-reviewed page is useful here because it refuses one Swedish water word. Leading water away in chapter 11, section 3 covers drinking-water supply, irrigation, process water, water for making artificial snow, and water for extracting heat or cooling. It also covers leading groundwater away and adding water to increase groundwater (infiltration). Those are statutory examples. They are not a data-center cooling catalogue and not a Falun or Staffanstorp litre.

The open-versus-closed split is the cooling sentence this page owns. If water is returned to the same water area, leading-away remains chapter 11 and the return sits under chapter 9. Extracting heat from surface water can be both a water operation and environmentally hazardous activity. An open system that leads surface water to a heat pump is a water operation. A closed system that circulates coolant in a collector is chapter 9 only. Do not rewrite “closed loop” as “no environmental file.” Chapter 9 is still a file.

Vattentäkt stays a defined word. Chapter 11, section 5 says leading water away for water supply, heat extraction or irrigation is also called a vattentäkt. HaV notes that vattentäkter have special rules, including legal control (rådighet) under the Act (1998:812) with special provisions on water operations, and that the possibility to declare a water-protection area under chapter 7 is limited to vattentäkter. Those sentences are about the legal object. They do not invent a campus well.

The permit clock remains on the water-rights page. Chapter 11, section 9 is the main permit rule for leading water away. Section 9 a lets certain smaller operations be notified. HaV’s notification page still says an activity may start at the earliest eight weeks after notification to the county administrative board, and that a notification has no rättskraft. Ordinance (1998:1388) section 19 still lists the notification classes used on that page, including at most 600 cubic metres per day and 100 000 cubic metres per year from a watercourse, or at most 1 000 cubic metres per day and 200 000 cubic metres per year from another water area. Do not invent a third Swedish hall threshold. Chapter 11, section 12’s “obviously no harm” exception is, HaV says, to be read restrictively. The house-need exception in section 11 is for one- and two-family properties. It is not a hall exemption.

What named primary sources show

HaV’s water-abstraction page remains the dated classification source for this cooling split. Keep the 14 February 2014 publication date and the 24 March 2022 review date attached. Keep process water, heat-or-cooling extraction, returned water, closed coolant and vattentäkt on the rows the page actually writes. Do not move those sentences onto a municipal welcome letter.

The water-operations ordinance, the water-operations act, Sveriges Domstolar’s water-operations page and HaV’s notification page remain the permit-and-notification stack. The water-rights page already owns that stack. This page only uses it to keep a cooling take from inventing a new cubic-metre class.

The Public Water Services Act remains the municipal drinking-water and sewer counterpart. Green Grid and ISO WUE sources remain intensity metrics. The discharge-permits page remains the evaporative and return-to-water file. Named Swedish halls stay on their own papers. No cited source here publishes a project-specific cooling-take litre for Meta Luleå, Microsoft Staffanstorp, EcoDataCenter Falun or atNorth SWE04.

A matrix instead of a water-free slogan

Draw one page with loop rows and evidence columns. Open take, returned take, closed coolant, municipal make-up and no on-site water are different rows. Chapter 11 right, chapter 9 file, VA contract, measured litre and WUE are different columns. Empty cells stay empty. A HaV classification sentence is a footnote, not a column of litres.

Do not invent a Swedish cooling-take league table from Ordinance (1998:1388) section 19 or from HaV’s closed-loop sentence. Those remain different objects from different years and methods.

ObjectWhat a source can showWhat this page will not invent

Closed coolant collectorHaV: chapter 9 only, not a water take“No environmental file”
Notification classOrdinance (1998:1388) §19 cubic-metre bandsA third hall threshold

Common misreads

The first misread is to treat a closed cooling loop as proof that no Swedish water file exists. HaV places that loop under chapter 9. Chapter 9 is still environmentally hazardous activity. The second is to treat a chapter 11 right as a measured cooling take. A permit or a notification is not a litre year. The third is to paste Ordinance (1998:1388) section 19 onto a municipal drinking-water tap.

The fourth is to treat WUE as a legal classification. The fifth is to treat the house-need exception as a hall exemption. The sixth is to treat chapter 11, section 12 as a default “obviously no harm” stamp. HaV says that exception is read restrictively. The seventh is to use a groundbreaking slogan as proof that the cooling take has already been classified.

What to ask next

Ask whether the loop leads water away, returns it to the same water area, or only circulates a coolant. Ask which letterhead — court, county board, environmental office or VA company — has received a paper. Ask which measured year, if any, sits beside the legal label. Ask whether anyone is talking about WUE, shoreline protection or discharge when they mean a chapter 11 take.

Then open the water-rights page, the discharge-permits page and the WUE page. If the operator will not name the loop and the desk, record the gap. Do not fill it from a water-free slide.

  1. Is the live paper an open take, a returned take or a closed coolant?
  2. Has chapter 9 been treated as “no file”?
  3. Has a municipal VA meter been pasted onto chapter 11?
  4. Has WUE been used as a water right?
  5. Has a data-hall litre chapter been invented?

What this does and does not prove

This page proves that HaV already publishes a split between an open heat-or-cooling take under chapter 11 and a closed coolant collector under chapter 9, and that those sentences are not a measured Swedish hall litre or a WUE.

It does not prove how many cubic metres a named Swedish hall takes. It does not invent a permit month. It does not treat a closed loop as the absence of an environmental file.

Empty cells stay empty. Until a later primary source names a Swedish hall’s cooling take with a dated loop class and a measured year, the rights-versus-take clock stays a method, not a census.
