World Sewer Operators WSO – a Global Expert Network

World Sewer Operators WSO

Founding a Global Expert Network

The sewerage research institute IKT – Institute for Underground Infrastructure is establishing the WSO worldwide peer to peer network, together with its collaborating sewer owners.

We invite you to join us, for the following reasons:

  • As urban areas around the world expand, provision of sewer and urban drainage infrastructure is becoming ever more critical.
  • The public, businesses and regulators are becoming more demanding.
  • There are challenges of ageing infrastructure, climate change and environmental protection to address.
  • Sewer network owners must keep on top of all of these and select from a myriad of technical developments coming their way.

To deal with these challenges, it is high time to build a worldwide peer to peer network
of sewer owners to address their needs by sharing their experiences and solutions with each other.
