Localization of sites for the use of wastewater heat recovery from the effluent of wastewater treatment plants in Baden-Württemberg

Zu sehen ist die Luftaufnahme einer Kläranlage mit Grauwasser-Recycling.

In this project, an analysis of the technically and economically usable potentials of heat recovery from wastewater at wastewater treatment plant sites in Baden-Württemberg for feeding into heat grids is carried out. The work includes a GIS-based analysis of the supply potentials at all wastewater treatment plant sites and of the heat demand of buildings in spatial proximity that can be supplied via heat networks, and a detailed analysis of technical development concepts at three wastewater treatment plant sites. The findings will be compiled into a selection of five to ten wastewater treatment plant sites with high heat utilization potential, prepared for public dissemination and transferred to a project initiation phase with the involvement of local stakeholders.
