How to drain away 37 million of litres of water in just 14 hours

Trollhätte canal, located in the Southwest part of Sweden, has a difference in altitude of 44 meters, handled by six locks. One single lockage demands 8000-12000 m3 of water. In May 2009, the lock system was closed down for maintenance and repair; this required four of the locks to be drained and kept dry for four days. Grindex pumps in the sizes Matador and Maxi were rented for the task. During 14 hours, a total of over 37 millions of litres of water were drained away.
