Water level

Schieland en de Krimpenerwaard regulates the water level in waterways and watercourses that run through its catchment area. An extensive system of waterways, brooks, canals, ditches, ponds, and storage reservoirs is used to store water in wet seasons and to supply water in dry periods. The main part of our area lies beneath sea level and consists of polders and reclaimed land. Pumping stations ensure that the water is always at the required level.

Because of the different ways the land is used (i.e. various agriculture and urbanisation), the area maintains 184 fixed water levels as the water level has a direct influence on the use of the land.  

On the west side of the river the Hollandsche IJssel, Schieland en de Krimpenerwaard uses a ‘boezemwater’ system (a two-step water pumping system). Here the water is pumped from the polder to the storage canal and from there into the river. East of the river the Hollandsche IJssel (in the Krimpenerwaard), a one-step system is used so the water is pumped directly from the polder into the river or, if more convenient into ditches. In time this method of pumping will be replaced by the generally accepted two-step pumping system.  

Water boards are not responsible for the management of ground water.
