History of Leif Koch A / S

In the early years of the company, the main tasks were locating leaks on gas pipelines, hence the flame in our logo. With the declining consumption of gas in the 1980s and 1990s, there was a shift to today, where the focus is on locating leaks on underground drinking water pipes. In 1980, his son Jørgen Würtzner Koch was hired as the head of the company's water leak department. In 1985, he joined the management as a partner with Edith and Leif Koch.
Six years later, in 1991, the baton was finally passed on and Jørgen became the main shareholder, as well as CEO of the company. Today, Jørgen has the main responsibility for the major foreign projects as well as consulting.
