Centrul de Cercetare Ingineria Apelor Subterane Laborator Colentina
Groundwater Engineering Research Center


The Groundwater Engineering Research Centre is housed in Colentina Laboratories, Faculty of Hydrotechnics, Technical University of Civil Engineering. The centre undertakes research activities both in the laboratory and in the field.

The centre developed an experimental site with five hydrogeological wells, up to 25 m in depth, and a geophysical investigations borehole, of 60 m in depth. The hydrogeological wells are equipped with submersible pumps with service discharges between 1 -5 l/s, and monitoring equipment for piezometric level vatiation (electrical GWT sensors).


Groundwater quality is monitored periodically by means of dynamic sampling and water samples are analysed for the following indicators: pH, temperature, conductivity, total dissolved salts, total alkalinity, permanent alkalinity, total hardness, temporary hardness, calcium, magnesium, ammonia, nitrates, bicarbonates, chlorides, oxide potential, sulphates, nitrites, iron, manganese, sodium and potassium.

The Colentina Experimental site was developed for two principal reasons: (1) quantitative and qualitative monitoring of the "Pietrisurile de Colentina" aquifer structure and (2) "in situ" hydrogeologic tests, for teaching purposes.

The 3D geologic conceptual model of the Colentina experimental site can be viewed in figure 1:

The CCIAS laboratory has available a multimedia room with PCs, notebooks, printers and video projectors. Most of the research activity performed at the centre takes place in this room, as well as some of the teaching activities ran by the centre (figure 2):
