Aquifer
A suitable aquifer is selected based on geological and hydrogeological conditions, required yield and water quality requirements.
Technical choices in brief
Well quality depends on geology, the selected aquifer, filter interval, pumping test and documentation. AKVA-M treats the process as technical infrastructure.
Pumping test
After drilling, pumping helps determine static and dynamic water levels and the recommended operating yield.
Equipment
Pump selection requires water levels, yield and casing diameter. If data is missing, it can be measured on site.
Water supply wells
Drinking water wells for homes, settlements, towns and companies.
- Selection of a suitable aquifer
- Installation of the filter interval
- Pumping test and water level measurements
Well repair and cleaning
Pumping, flushing, diagnostics and repair of existing wells when the structure allows it.
- Yield checks with pumps and compressor
- Assessment of clogged filters and deposits
- Repair approach based on actual condition
Well abandonment / tamponage
Abandonment of unusable wells with technically correct sealing and filling.
- Pump removal if it is inside the well
- Cleaning and interval filling
- Work planned according to current requirements
Pump and pressure tank installation
Selection and installation of deep well pumps, pressure tanks and connections.
- Pump selection by levels and yield
- Pressure tank and connection installation
- Measurements when well data is missing
Wells for heat pumps
Deep well solutions for heat pump systems where land area is limited.
- Solutions with cooperation partners
- Two-well systems are typically evaluated
- A shared aquifer is important
Documents and permits
Support with well documentation and technical data preparation.
- Checking boundary plan and requirements
- Preparing data for well documentation
- TODO: verify current institution list

Often important water-bearing horizons. The filter interval must be placed precisely in the aquifer.
Work process
A clear sequence helps clients understand what happens before drilling, on site and after handover.
01
Consultation
We clarify the site, water demand, available data and desired timing.
02
Site and document review
We check which approvals, boundary plans or institution requirements apply to the project.
03
Drilling
The well is drilled at the selected location down to a suitable aquifer.
04
Filter and pumping
The filter interval is placed in water-bearing rock, then the well is pumped and measured.
05
Equipment
If needed, a deep well pump, pressure tank and connections are selected and installed.
06
Handover and recommendations
The client receives technical information and recommendations for well operation.
