Executive overview
Key findings
Over 150%: groundwater abstraction on Zealand as a share of the estimated sustainable resource (GEUS, 2023 assessment, excluding climate change)
12 million m³ a year: HOFOR's projected 2040 shortfall in the capital region, with demand of 73 million m³ against 2024 capacity of 61 million m³; 16 million m³ if the past 15 years' capacity decline continues
3.6 million m³ a year: HOFOR capacity lost to PFAS and pesticide contamination in 2024
50.9%: share of 2,272 tested drinking-water supply boreholes with a pesticide detection in 2023; 12.2% exceeded the single-substance limit

Buyer relevance
Who the report is for
Capital-region utilities and municipal planners
Benchmark the 12–16 million m³ 2040 gap against the projects and protection measures now under way.
Treatment and monitoring suppliers
Size demand for pesticide and PFAS treatment where 50.9% of tested supply boreholes showed a pesticide detection in 2023.
Industrial and Power-to-X developers
Plan for groundwater as a last resort on Zealand, where Power-to-X demand of 20–25 million m³ is estimated for 2040.
Policy and public-affairs teams
Prepare for the 2027 decision on protecting vulnerable groundwater-forming areas and the reuse review due by 2029.
03
Decision scope
Questions answered
Is Denmark running out of water?
Not nationally: water stress was 26.63% in 2023. But Zealand abstracts over 150% of its estimated sustainable groundwater resource, and HOFOR projects demand of 73 million m³ against 61 million m³ of capacity by 2040.
What is reducing supply capacity?
Contamination: HOFOR lost 3.6 million m³ a year of capacity to PFAS and pesticides in 2024, at 8 of about 50 well fields.
Can Denmark turn to desalination or reuse?
Desalinated output was 0.00 km³ in 2023 and new plants are permitted only by exception; a January 2026 decision excludes treated wastewater for farm irrigation until a review due by 2029.
How did 2026 test the system?
Spring rainfall was 103.4 mm, 22% below normal, and HOFOR reported 2026 on course for the highest capital-region consumption in more than 20 years.
