Since the 1970s, wesernetz Bremen GmbH has been operating the district heating (FW) transport pipeline "Oststrang" in the east of Bremen. In order to be able to continue to guarantee a secure and economical supply of customers supplied with district heating, the eastern line will have to be renewed in sections over the next few years. In the course of planning, service providers for planning services for network construction measures (gas, water, electricity and district heating networks) with a focus on district heating are also sought in large dimensions (DN 700) and longer routes (> 2 km) in urban environments.
