BTEE can perform any type of hydro-geological study for:

• Finding new water resources such as springs or wells and assessing them qualitatively and quantitatively. Sizing catchment basins. Oversight of the work can also be carried out.
• Exploiting resources by designing sustainable extraction methods.
• Protecting water resources by defining the boundaries of protected areas as required by legislation.

Investigations include organising and monitoring drilling work, performing tracing tests, taking samples for regulatory chemical tests, taking in-situ chemical and physical measurements and monitoring spring or water course flow rates.
