UIM services essential for society

Ageing sewerage systems are a major problem for society

Poor current state of sewerage systems
Aging infrastructure Significant investment need Consistent service need Threat from severe weather

Average network ~40 years old and in some cases they are almost two times past their life expectancy

Only ~1% p.a. of the sewerage systems are renewed in Norway

~30% average leakage rate in Norway

Severe weather further exacerbates sewerage systems condition

UIM services essential for society

  • Increase the life of sewerage systems
  • Continuous maintenance prevents flooding and the spread of water-borne diseases
  • Integral part of the sewerage system value chain – essential for society every day of the year
  • Drainage and other services mission critical for institutions from utilities to hospitals
  • The UIM industry has its own UN sustainability target (#6 water and sewerage systems) and is crucial for implementation of UN target 11 and 13
