Kurzbeschreibung
(Englisch)
Swiss Parliament has adopted the motion 22.3702 Jauslin, which instructs the Federal Council and all federal offices concerned “to change the [legal] regulations in such a way as to enable the geothermal potential of the subsoil to be optimally exploited including the seasonal storage of heat”. More specifically, the motion expresses “the need to increase optimally the limit for groundwater temperature change through heat use or storage”, currently set to a maximum of 3 ºC at 100 m downward of the facility (Water Protection Ordinance). In doing so, the protection of groundwater used as drinking water as well as the protection of habitats dependent on groundwater must not be affected. With regard to the 3 °C rule, the Water Protection Ordinance does not distinguish between groundwater suitable to be used as drinking water and groundwater that is not suitable. However, primarily groundwater that is not suitable for drinking water use should be able to be used for heat storage, especially deep groundwater if its chemical composition makes drinking water use impossible.
