For a Copenhagen hardness setting, use HOFOR's address search and keep the result's context. On its softening timetable page, HOFOR tells readers to enter an address and then click the blue icon to open the information box for that location. Open the hardness and softening map.
No address-specific result was retrieved for this article. We cannot give a current value or a softening completion date for your accommodation. The useful next step is to make the lookup with the actual address, rather than choose a number attached to Copenhagen in an old summary.
Read the location and unit together
Keep the address you searched for beside the information box. Check whether the text gives present hardness or an expected change, and retain any units and date labels shown. If a measurement or update date is missing, ask HOFOR which period the result represents. The visible timetable instructions do not establish an update date for every address result.
HOFOR's project overview describes a gradual target of 10 to 12 dH, which it calls medium-hard water. It says customers will hear from the utility when it is time to adjust appliances and detergent dosing. A project target does not establish that your tap has reached it. Read the softening project guidance.
That is especially relevant in rented accommodation. Before changing a dishwasher or a private softener, check the address result and the equipment instructions with the person responsible for it. A city's overall project timetable cannot tell you how an individual appliance is configured.
Why neighbouring results can differ
HOFOR's Copenhagen supply page says water from regional works mixes before delivery and again in the city's network. Its description is explicitly for normal operating conditions. It names several works contributing to the supply of each listed city area. The page does not provide today's source proportions for a particular property. Copenhagen's published supply arrangements.
Our practical reading is to keep a works result separate from an address result. A works report can describe water leaving that works; the supply description explains why you should not assume an unchanged value reaches every customer. Use the location identified in the result when deciding what comparison you can make.
Older news is useful history
HOFOR's announcement of 27 March 2024 described softer water reaching parts of Hvidovre, Rødovre, VallensbÌk and Albertslund. It also introduced an address-search map. That announcement concerned parts of those municipalities at that time, not completion across Copenhagen in October 2026. Read the dated 2024 announcement.
An old news item can explain why a previously quoted hardness figure differs from a newer lookup. It cannot by itself resolve the current figure. Keep the older value if you are recording a change, but label the old report's location and period instead of silently overwriting its date.
A page date is not a sample date
HOFOR's page about drinking-water contents shows publication on 11 April 2012 and an update on 4 September 2025. Those dates describe the explanatory page. It says groundwater naturally contains salts and minerals, and discusses water treatment and monitoring. They are not collection dates for an address's hardness reading. See the dated contents page.
The timetable, project overview and Copenhagen supply page have no established publication dates in this research. All five sources were read on 14 October 2026. For broader travel guidance, see the Copenhagen city page. If your question concerns equipment, our pitcher-filter and softener comparison explains the different tasks before you choose a device.
