Buyer relevance
Who the report is for
Tunnelling and civil contractors
Time bids around the Svanemøllen main contract, expected in August 2027, and the Kalvebod Brygge and Valby tunnels due in 2027 and 2029.
Treatment and process suppliers
Track HOFOR's remaining waterworks (Islev in tender, Gørløse in design) and the BIOFOS and ReWater treatment plants, with their decision dates.
Coastal engineering consultants
See which coastal work is funded now (DKK 912.1 million for 2026–2029, DKK 164 million co-financing in 2026) and which depends on an unagreed national plan.
Lenders and credit analysts
Compare 2022 sector investment of DKK 9.96 billion with DKK 40.1 billion of debt, borrowed mainly through KommuneKredit.
03
Decision scope
Questions answered
Which large Danish water projects are closest to contract?
Copenhagen's cloudburst tunnels: the DKK 4.1–4.6 billion Svanemøllen tunnel went to tender on 2 June 2026, with the contract expected in August 2027.
What is at risk on cost?
HOFOR says the Tinghøj reservoir rebuild's first estimates are significantly higher than an earlier DKK 2.3 billion figure for reservoirs and mains, and a decision waits on a Q4 2026 analysis.
When will Copenhagen decide on its new treatment plant?
BIOFOS's board is due to take an in-principle siting decision on 13 November 2026; the investment decision follows in 2031, with construction set for 2032–2045.
How is the investment financed?
Through tariffs and municipal-lender debt: the 182 municipally owned companies owed DKK 40.1 billion in 2022, mainly to KommuneKredit.
