Interwell S.r.l. products

The wellpoint system causes the temporary lowering of the water table to enable dry excavations in aquifers in the most practical and economical manner. The principle of operation consists essentially of draining underground water through a set of filter tips (the wellpoints) installed in the ground at a depth greater than that of the bottom of the excavation. It consists of a set of horizontal manifolds headed by a suction pump fitted with vacuum pump ; of horizontal manifolds which branch off featuring variable centre distances, flexible joints connected to the lifting tubes driven into the ground to the desired depth. The wellpoint is installed at the end of the lifting tube that allows for aspiration of the water without removing the solid particles of the soil.
