Half of The Netherlands consists of polders. This is land that we have reclaimed from the sea. Waternet and the Regional Public Water Authority Amstel, Gooi en Vecht ensure safe polders. We also ensure that there is clean and sufficient water.

Protection against the water

The people who live and work in the polder need to be protected against the water. We do this with dykes and pumping stations, however there is much more to it. For example, regular maintenance of ditches and banks is important. We also ensure that the water remains at the correct level.


Does action need to be taken? For example, the construction of a dam? Or do the ditches need to be broadened? Then we will make sure it is taken care of. Find out where we are working in your area at our Work in progress page.
