Water management in the Netherlands has always been very important to the National and Public interest. Dams are a vital link in these management efforts. Often, repairs and maintenance operations are conducted only after the water has been fully evacuated, or its levels greatly reduced. These undertakings generally carry with them enormously high costs.

C.O.W. Diving Company bv has extensive experience in the underwater repair and maintenance of dams for numerous water authorities throughout the country. By performing these operations underwater, without the need for additional damming and water removal, repair and renovation can be accomplished with the greatest possible economic and practical benefit to the client.
