Bremen – October 30, 2026 -- At current reinvestment rates, fully renewing Europe's drinking water networks would take between roughly 90 years in Belgium and 1,000 years in Finland, according to a new study by engineering consultancy Sweco.
The study, titled "Old Pipes, New Pressure" (German: "Alte Rohre, neuer Druck"), uses EurEau investment data from 2026 and reported network lengths. It finds that spending levels alone do not show whether networks are being renewed at a sustainable pace.
