In 2012, the Greenland water supply company, Nukissiorfiit, determined that alternative leak detection methods were necessary for locating and repairing leaks at its district heating plant at Qaqortoq, which lost 5-7m3 of water daily. Nukissiorfiit contacted Leif Koch to perform leak detection and repair at the plant in Qaqortoq.

Leif Koch determined that trace gas was the best tool for finding the leaks at the district heating plant, and sent Leakage Operator Jan Jørgensen to Greenland to work on the site. Jan localized and found nearly all the leaks in the pipe system, which ranged from 180 I/min to 0.5 I/h.

After the week-long project ended, Jan taught an instructional course about Leif Koch’s methods to local staff. Jan is an extremely valued member of Leif Koch and has over 40 years of experience as a Leakage Operator.
