Which ADLER drilling rig is the right one for well construction?

Well construction is a demanding task that requires precise technology and reliable machines. Whether for private garden wells, agricultural irrigation systems or commercial water supply – choosing the right drilling rig is crucial to the success of your project. ADLER Arbeitsmaschinen offers a range of compact, powerful and German-made drill rigs that are specifically designed for well construction. In this blog post, we present the B 15, B 25, B 50, B 75 (incl. Pro) and B 200 models and provide recommendations on which rig is best suited to your well drilling requirements.

 

What needs to be considered when building a well?

Well drillings are used to tap groundwater for various purposes, such as garden irrigation, drinking water supply or garden ponds. The most important factors when choosing a drilling rig are:

• Drilling depth: Depending on the groundwater level, the depth varies from 6 m (near-surface wells) to over 100 m (deep wells).
• Soil conditions: Light soils (e.g. sand, loam) require different equipment than hard soils (e.g. rock formations).
• Accessibility: Many well construction projects take place in confined spaces, such as private gardens, which requires compact machines.
• Drilling method: Flush drilling is the most common method for well construction as it is efficient and versatile.

ADLER drill rigs are known for their compact design, robust rubber crawler tracks and high flexibility. They are particularly suitable for projects with limited space and offer a long service life with low maintenance costs.

ADLER drilling rigs for well construction

• Area of application: Deep wells for large infrastructure projects, e.g. municipal water supply or industrial applications.
• Recommendation: For large companies or specialized well construction companies that require maximum performance.

Practical tips for well construction

• Permits: In Germany, every well drilling must be registered with the responsible water authority. An additional permit from the mining authority may be required for deep wells over 100 m.
• Drilling method: Flush drilling is the preferred method for well construction as it is efficient and versatile. All ADLER units support flush drilling, with larger models (B 50, B 75, B 200) offering more powerful flush pumps.
• Transport: The B 15, B 25 and B 50 models can be transported on a 3.5 t trailer, which saves costs. The B 75 and B 200 require larger transport vehicles.
• Accessories: ADLER offers accessories such as flushing pumps, drilling sets and hydraulic boom clamps that increase efficiency. For environmentally friendly projects, an HVO-powered compressor (e.g. Atlas Copco Y35) can be added.
• Maintenance: ADLER machines are known for their durability. Regular maintenance by GSK Baumaschinen ensures a long service life.
