Questions answered

What is the largest named water project in Germany?

Bodensee-Wasserversorgung's Zukunftsquelle, estimated in 2025 at EUR 4.6 billion to 2046; it is still in planning and was reported in November 2025 as having to be scaled back.

How much does the sector invest compared with what it needs?

About EUR 10 billion a year now, against an average of about EUR 40 billion a year projected for 2025–2044 in a study for VKU.

Can water projects use the EUR 500 billion infrastructure fund?

Water is not among the nine federal investment areas; the EUR 100 billion Länder share does not name water but does not exclude it, and Hessen confirms water measures are eligible.

Who is lending to German water utilities?

Mainly the European Investment Bank, which signed EUR 400 million for Berlin, EUR 300 million for Hamburg, EUR 157.5 million for Cologne and EUR 500 million for Emscher-Lippe.
