kinderdijk holland!
Because large parts of the Netherlands are reclaimed parts of water, about 70% of the country is below sea level. The impact which this has on the dutch drainage system is enourmous. The draining of the country doesn't take place the natural way, this causes that all the water from rain which falls on the country stays here. So in order to prevent the dutch inhabitants from drowning a large drainage system was formed.
For instance, the drainage system of the Alblasserwaard consist of three level system.
The first and lowest level is the polder level. The alblasserwaard is divided in several sections, called polders which means literally "a piece of land below sea level surrounded by a dike". Every polder used to have its own windmill which pumped the water one level up, into the so called boezem.
The boezem level is the second level.
The boezem water is collected at Kinderdijk where it will be pumped up another level by each of the 16 windmills. The water is pumped up into a reservoir.
The third level and the highest level is the reservoir
The water stays in the reservoir until the level meets the average high tide of the river, then the water is discarded onto the river lek which takes it via Rotterdam to the sea.
