Standardbohrung

Saugbohrverfahren

EMAS manual well drilling is a method for drilling small-diameter tube wells by hand. The drilling method is a hybrid between washboring, percussion and rotary drilling. It permits to drill through all kinds of loose soils, as well as consolidated materials and light rock. It will not, however, penetrate hard original rock or boulders (e.g. ancient river beds underground). The usual diameter of the tube well is 37 mm.

Pedalpumpe

EMAS manual well driling is a method for drilling small-diameter tube wells by hand. There are different variants to the technique, depending on soil type and required depth. This technique uses sludging in combination with temporary casings of different diameter.

All EMAS handpump designs use glass marbles and standard PVC fittings as return valves. Different pump designs are available for high pressure, high quantity, hand-powered, pedal-powered, and windmill powered. This pump is fitted with a pedal, so it can be operated by foot. The resulting movement is ergonomic, and can be sustained for a long time.
