ABSTRACT:
An installation for protecting ground water underneath a dump has at least one tunnel driven longitudinally through the ground underneath the dump and an array of casing pipes passing through the ground, each having a lower end opening into the tunnel, and each formed with a multiplicity of throughgoing holes. These casing pipes are longitudinally spaced to receive liquid from their surroundings and conduct it to the tunnel. Respective inner tubes spacedly received in the casing pipes are provided to service the respective casings and their holes. These casings are installed using standard oil-drilling equipment and techniques. Once the tunnel has been driven the bores are slant drilled to it and standard perforated well casings are installed in these slant-drilled bores.
