Project 11: Wupperverband – Implementation of a decentralized heat grid

Planning Realisation Monitoring Evaluation
Wupperverband – Implementation of a decentralized heat grid

Project leaflet

In the future Europe will have to answer questions about its security of energy supplies, and must begin to discuss the impact of energy needs on climate change and energy supply. The transition from current energy practices to the sustainable use of energy is essential. One possibility to reach this is to improve decentralized energy concepts. It is especially important that this generation of Europeans is aware of these problems and possible solutions.

Main questions to be answered

  • How much thermal energy can a waste water treatment plant provide for the surrounding peripherals?
  • Can the surplus thermal energy of the WWTP be used for cooling operation buildings by an absorption chiller?


  • Development of new decentralized heat grids.
  • More efficient use of the thermal energy in the waste water and in the sludge.
  • Create a self-sustaining waste water treatment plant, at least from a balance standpoint. Also the transition will be      made from an energy consumer to an energy supplier.
  • To integrate the waste water treatment plants, a sludge incinerator and the surrounding peripherals in an energy master plan in order to consume less energy from existing resources and produce effective decentralized energy concepts.
  • Operation results of an absorption chiller.
