Groundwater heat utilization Kloten (ZH)

Ecosens AG carried out hydrogeological investigations in a district of Kloten for the replacement and expansion of two heating centers in order to use groundwater for heating and cooling purposes. In addition to the geological surveys of the boreholes and planning of the well expansion, pumping tests were carried out and evaluated. Computer-aided thermal groundwater modeling was also carried out using the "Feflow" software to determine the number and positions of the extraction and return wells as well as the mutual thermal influences of the systems. This thermal groundwater modeling was also used to check compliance with the legal requirements for groundwater.
