Water Technology Alliance, California
Danish solutions to American problems
California has the highest population in the United States, with well over 39 million. inhabitants. In the last few years, they have experienced the worst drought period in more than 100 years. The pressure is enormous as the water resources in the area dwindle. It requires stable and efficient solutions throughout the water distribution, to secure the water they have. Against this background, the Danish-American water alliance was created by the Water Technology Alliance (WTA).

Services aimed at leak detection
Here at Leif Koch A / S, we offer everything from leak detection of our top professional leak operators, to sales of modern instruments as well as personal advice and relevant support.
Prevent or treat unnecessary waste
Leaks are inappropriate as the clean drinking water seeps through the leak and back into the subsoil instead of out to the consumer, draining both environmental and economic resources. Leif Koch A / S monitors the pipeline network with modern technology and in-depth expertise. In this way, the time from the time the leak occurs until it is repaired is reduced and precious resources are saved.

About courses, products, projects and more
Leif Koch - experience since 1974
Leif Koch A / S is a privately owned family business, which was founded by Edith and Leif Koch in 1974. This makes us Denmark's oldest leak detection company, with almost 50 years of experience.
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.
