Along the Oranjekom (yellow)
Varied walk through forest and dune and along the place where the pre-purified water from the Lek Canal flows into the area to be purified naturally through the dunes
At the entrance you follow the yellow posts. We walk over a wooden platform to the visitor center. The visitor center is located in a former pumping station. In the past, water was pumped here from the dune to the water purification plant on the other side of the road. There are still large pumps and in a glass plate in the floor you can look in the basement, where there are large pipes, through which the water flowed. At the desk you can get information about the dunes. There are also booklets and other things for sale. We now cross a narrow bridge and walk through a forest area (Kombos called). Coniferous and deciduous forest alternates here. Halfway through the walk we reach the Museumduin via the Sprenkelveld, where the path continues to the Duivendrift and the exit. The Museumduin owes its name to a bunker where art treasures were stored during the Second World War.
Here, purified water comes into the Amsterdam Waterleiding Duinen. After this, the water is introduced into the infiltration area, where it falls into the soil. This water stays in the ground for about three months. Water enters the Oranjekom via channels in the dune area. The distribution pond is lower than the Oranjekom. There are binoculars where you can see the differences. The Leiduin after-treatment plant makes clean and reliable drinking water.
This infiltration area was constructed in the fifties. Thanks to this system, the dunes provide sufficient drinking water. The infiltration area is not accessible in a few places.
The canals also form a home for the birds that live along the water. Coots and wild ducks can be found in the dunes in the summer.
