Les eaux souterraines contribuent pour plus de 80 % à l’alimentation en eau de la Suisse. C’est la raison pour laquelle leur exploitation optimale et leur protection sont une tâche prioritaire des collectivités publiques. On appelle aquifère une formation géologique qui peut contenir et conduire dans ses pores de l’eau souterraine en quantité appréciable. Sommairement, on peut distinguer parmi les gisements d’eau souterraine de Suisse, six types d’aquifères majeurs. Ils sont représentés par des éléments exemplaires dans les coupes et les graphiques de la planche.
Der Anteil des Grundwassers an der Wasserversorgung der Schweiz beträgt über 80 %, weshalb eine nachhaltige Nutzung und der Schutz dieser natürlichen Ressource eine vordringliche Aufgabe unserer Gesellschaft ist. Als Grundwasserleiter oder Aquifer bezeichnet man eine geologische Formation, die in ihren Hohlräumen Wasser in nennenswerter Menge aufnehmen und weiterleiten kann. Vereinfacht können in der Schweiz sechs Haupttypen von Aquiferen unterschieden werden. Sie sind mit Fallbeispielen anhand von Profilen und Grafiken auf der Tafel vorgestellt.
Le acque sotterranee forniscono l’80 % dell’approvvigionamento idrico della Svizzera. Pertanto, la protezione di queste risorse naturali ed il loro sfruttamento ottimale diventano compiti di primaria importanza per la collettività. Per acquifero si intende una formazione geologica capace di contenere nella sua porosità quantità apprezzabili d’acqua e di permetterne la circolazione sotterranea. Sinteticamente si possono definire per la Svizzera sei principali tipi di acquifero, illustrati e descritti, con profili e grafici, secondo la casistica.
Groundwater is the source of more than 80 % of the water supply of Switzerland. For this reason, an urgent task of both the public and administration is to seek a sustainable exploitation and optimal protection of groundwater resources. An aquifer is a geological formation in which a large amount of groundwater circulates through openings. In Switzerland, it is possible to distinguish roughly between six major types of aquifers. Representative examples are schematically illustrated by means of cross-sections and diagrams on the map page.
