Repair, cleaning and decomissioning of boreholes

We perform maintenance and safe decomissioning of damaged or unused wells.
All services are provided year-round, even during the winter season. We collaborate with the Ministry of the Environment, the Czech Meteorological Institute, and various water utility companies.

Any HG boreholes

We provide consultations, diagnostics, and implementation services for various types of hydrogeological wells—water wells, monitoring wells, and infiltration boreholes.

200m deep

We perform drilling, cleaning, and well yield verification (hydrodynamic pumping tests) for wells of depths up to 200m.

Restoration of old wells

We provide mechanical and chemical cleaning as well as re-equipping of wells. We address issues such as sediment buildup, changes in the yield of hydrogeological wells, or mechanical damage to the well.

Modern technology

For maximum accuracy and efficiency, we use the latest diagnostic tools, inspection cameras, and equipment for well cleaning.

Long-term preservation of well quality and yield

Our services ensure not only the functionality, safety, and smooth operation of the well but they also extend the lifespan of the entire system, thereby reducing costs.

What we provide

Borehole inspection

Detailed exploration

Using a camera system, we conduct a visual inspection.
The camera displays the internal condition of the well, including the presence of sediment, corrosion, potential cracks, or mechanical damage.

Flow testing

We verify the flow rate and performance of the well—measuring pumping capacity and identifying issues such as reduced flow or fluctuating water quality.

Sample collection

We collect samples for laboratory analysis of water quality to assess its condition and propose appropriate improvement measures. We also develop a cleaning plan and outline any necessary repairs.

Repair and cleaning

Mechanical cleaning of boreholes

Using mechanical tools or airlift, we remove sediment, sludge, sand, and other mechanical impurities that accumulate in the well during its operation.

Chemical cleaning of boreholes

To remove deposits that mechanical cleaning cannot fully address—such as mineral deposits, iron precipitates, organic impurities, and other harmful substances—we apply chemical agents.

Well re-equipping

Particularly for older wells which are worn down or corroded, we provide re-equipping with new and more modern components.

Borehole decomissioning

If a well is no longer operational or does not meet legal standards, we perform professional decommissioning in compliance with applicable legislation and environmental principles.
