3 Important Criteria to Ensure Your Well Construction Project Doesn't Fall Through
Whether it’s a fire hydrant or a garden fountain, construction projects that affect groundwater must comply with legal, technical, and environmental requirements—and for good reason.
Otherwise, the authorities will halt your project again once construction begins. That means high costs—and still no well.
So it’s best to find a provider that understands and meets these three criteria:
1. Environmental Protection
The conservation and preservation of water and soil resources are important concerns. For this reason, you should only work with a provider that is certified according to DWGW W-120-1 and is familiar with the legal requirements.
2. Permits
Before the project begins, the nature conservation and water authorities will be contacted. The regulatory requirements for approval of the project must be met.
3. Experienced well drillers
Your well contractor needs specialized training, experience, and the right equipment.

Frequently Asked Questions
How long does it usually take to complete a well project?
What factors influence the cost of the project?
Do you also offer maintenance and repair services for wells?
What are the typical risks and problems to watch out for when constructing a well, and how does your company prevent them?
Typical risks and problems associated with well construction can include geological conditions, such as soil layers that contain very little water. In addition, there are now often regulatory water protection requirements that prohibit the use of groundwater for a well.
Our company avoids such problems by conducting a thorough site assessment.
