Why this service?

Finding water — and making sure it is good.

Siting a borehole in the right place and knowing its yield and water quality: this is the basis of every drinking water or industrial project.

Services offered

  • 01Hydrogeological reconnaissance and water resource study
  • 02Siting of water boreholes, with geophysical support
  • 03Monitoring of borehole and well construction
  • 04Pumping tests (step and long-duration) and safe yield
  • 05Piezometric measurements and groundwater monitoring
  • 06Water quality analyses: drinking water, solar panel cleaning water, industrial water
  • 07Studies for drinking water supply in towns and villages
  • 08Hydrogeological impact studies of mining and industrial sites
Methods & standards

Recognised methods, reliable data.

Sampling and analyses according to recognised protocols, compared with the applicable guideline values — notably those of the WHO for drinking water.

Frequently asked questions

Have a question?

How do you choose where to drill a well?

Through a hydrogeological reconnaissance supported by geophysics, to maximise the chances of finding a good yield.

Do you analyse solar panel cleaning water?

Yes, as well as drinking water and industrial water.
