Insurance for well drillers and pipeline contractors in Germany

Well drillers and pipeline contractors in Germany work where nobody can see: underground, in the groundwater and next to cables that are often missing from the plans. A drill bit through a power line, drilling fluid in a neighbour's cellar, hydraulic oil in the soil: losses like these quickly exceed the value of the job. Here is what a business should insure and what it costs.

Insurance for well drilling and pipeline construction

The question almost everyone asks first

Does my public liability pay if drilling pollutes the groundwater?

Only if environmental risks are expressly included. Well drillers need both environmental liability for claims by third parties and environmental damage cover for clean up ordered by the authorities. Many standard trade policies in Germany leave this out or cap it low. Ask for both in writing.

What goes wrong in this trade

  1. 01

    Hitting a utility

    The drill hits a power cable, gas main or fibre line. Network operators claim repairs and often the cost of the outage.

  2. 02

    Polluted groundwater

    Hydraulic oil, diesel or drilling additives get into the ground and the authority orders remediation.

  3. 03

    Subsidence and flooded cellars

    Dewatering or washed out soil cracks a neighbouring building, drilling fluid pushes into a cellar.

  4. 04

    Rig and rods

    Rods jam in the hole, a rig tips over on soft ground, the compressor fails halfway through a job.

  5. 05

    Theft from site

    Pumps, generators and tools often stay overnight on open ground.

  6. 06

    Trench collapse

    Pipeline work means people in trenches close to heavy machinery.

Practical tips from your broker

  1. Make sure your public liability includes both environmental liability and environmental damage cover, with limits high enough for soil remediation.
  2. Check for low sub limits on damage to underground cables and pipes.
  3. Get utility records before every job and keep them on file.
  4. Notify drilling one month in advance under section 49 of the Water Resources Act.
  5. Ask for rods and tools lost in the hole to be included in your machinery cover.
  6. Lock pumps and generators in a container overnight.

Frequently asked questions

Questions and answers

Do well drillers in Germany need public liability?

Public and commercial clients ask for it almost every time.

Without it you pay for every damaged cable and every pollution claim yourself.

What is the difference between environmental liability and environmental damage cover?

Environmental liability pays third party claims, such as a neighbour's polluted well.

Environmental damage cover pays clean up ordered by the authorities.

Well drillers need both.

Do I have to notify a borehole?

Yes.

Work that may affect groundwater must be notified to the authority one month before it starts,

under section 49 of the Water Resources Act.

What does insurance cost for a well driller?

Public liability with environmental cover starts at about €900 a year in our quoting work.

With rig and vehicles a small business usually pays €5,000 to €11,000.

Are lost drill rods insured?

Not under liability.

Some machinery policies offer an extension for rods and tools in the hole,

often with a separate excess.

Are my employees covered for accidents?

Yes, employees are insured by law under section 2 of SGB VII.

As owner you need voluntary statutory cover or a private accident policy.
