FLOOD control is an important issue for the Netherlands as the largest part of its surface area is vulnerable to flooding. Water control boards are the independent local government bodies responsible for maintaining flood protection systems.
In the Dutch region of Overijssel the local water board governs the water in the agricultural polders (a low-lying tract of land enclosed by embankments, with no connection to outside water sources or reservoirs). One of their refurbishment projects concerns a pumping station built in the year 1933 which has been designated as a so called municipal monument.
The project started with the installation of temporary pumping equipment, consisting of three new diesel-driven pump units from BBA Pumps. During the renovation these pumps will take over from the pumping station without any loss of capacity, and as such they will guarantee the correct water level.
Two BA300K D324 diesel driven pumps, which together account for a maximum of 46 m3/min, have both been set up next to a big 20in pump set, type BA-C500S11 D711 with a capacity of over 60 m3/min. The pumps have been connected to a modern operating system making it possible to automatically and independently start and stop them, depending on the volumes of water flowing in from the polders nearby. These super silent pump units can even continue working during the night, without causing any noise disturbance to the surrounding environment.
The flood control pumps are very well suited to controlling water levels during heavy rainfalls and to prevent flooding, in addition to acting as a temporary pumping station.
