The Finnish company Kymenlaakson Vesi Oy supplies the towns of Kotka, Anjalankoski and Hamina with drinking water. Before the new ‘Utti-Keltakangas’ water pipeline was built, there was only one single DN700 DCI pipeline from the Utti waterworks to these towns. This pipeline has been in operation since 1992 and is approximately 30 km long. In order to ensure a reliable water supply to the towns while also increasing the water capacity, a new pipeline was built – a PEH 560 with a length of 25 km.

The equipment needed for this project included 47 Hawle E2 DN600 gate valves, two needle valves, 27 different valve chambers, and several small E2 gate valves.
