    Deep Wells

    Deep wells are used to carry out dewatering, drinking water extraction and remediation of contaminated aquifers. Deep wells are best suited for operation in aquifers with permeability coefficients [kf] from 1x10-2 m/s to 1x10-5 m/s. They are installed by drilling a borehole with a diameter from 324 mm to 2000 mm at depths up to 300 m. Depending on the diameter, the site's geological conditions and the intended depth, the borehole can be sunk using...

    Vacuum Deep Wells

    Vacuum deep wells are used for dewatering and site decontamination in regions with low subsoil permeability and low-lying aquifers Vacuum deep wells are operated effectively in aquifers with permeability [kf] coefficients ranging from 1x10-5 m/s to 1x10-7 m/s. They are installed by drilling a 324 mm / 700 mm diameter borehole up to a depth of 50 m. Depending on the diameter, the site geology and the intended depth, the borehole can be sunk by casing...
