In the city of Odense – Denmark’s third largest urban area and hometown of world famous fairytale writer Hans Christian Andersen – the water utility VCS Denmark has successfully reduced water loss in the pipeline network to only 4 % (2020).
At 0.60, the utility’s Infrastructure Leakage Index (ILI) is among the best in the world.

These impressive figures are the result of a dedicated effort spanning several decades.

Key elements include:

  • Changing the water distribution system to a branch network (rather than ring-connected)
  • Restructuring the network into zones and relatively small district metered areas (DMAs); 2,150 consumers on average
  • Systematic leakage detection and reduction
  • Reliable online monitoring of leakages (SCADA supervision)

Leakage detection in the field is now only used to pinpoint leakages detected by the SCADA supervision.

Sharing knowhow worldwide

VCS Denmark has extensive practical experience in planning and implementing leakage detection, and utilities around the world have benefited from this experience. For example, VCS Denmark has worked with Danish Water Services and Grontmij in Myanmar, securing a reliable water supply to the citizens of Yangon.


We are an active partner in 3VAND – a strategic collaborative partnership consisting of the leading water utilities in Denmark: HOFOR, BIOFOS, Aarhus Vand and VCS Denmark.
