The Regional Public Water Authority Amstel, Gooi en Vecht

The Netherlands is a water-rich country. Rivers, lakes and canals all define the appearance of the country. We need the water, but we also need to protect ourselves from it. Dykes must be kept safe and the water clean and healthy. Nor may the water rise too high or fall too low. For 850 years now, the Water Authorities (waterschappen) have seen to this.

The area

The Regional Public Water Authority Amstel, Gooi en Vecht manages an area of 700 square kilometers extending over the provinces of Noord-Holland, Zuid- Holland and Utrecht. A large majority of this area lies below sea level. If we do not contain the water these regions will flood. This is why dykes, pumping stations, locks and polders are of vital importance, especially in this part of the Netherlands.


  • Safe dykes: Safe dykes for the protection of humans and animals have our highest priority. We are responsible for a total of 1093 kilometers of dykes. Each dyke must meet certain requirements as to strength and height. By monitoring these dykes continuously we ensure that we can take timely measures if required. This is necessary to guarantee their safety.

  • Sufficient water: The Water Authority ensures there is sufficient water in the right place. Not too much, not too little. This depends, among others, on the land-use type: agricultural areas require different groundwater and surface water levels than cities. Too much water is obviously a problem, but the same applies to too little water: shipping can be disrupted and agricultural land can dry up. The Water Authority weighs the various interests and determines the right water level for each area.

  • Clean water: One of our primary responsibilities is ensuring clean water in canals, drainage channels and other waterways; an extremely complex task. Our waste water treatment facilities clean 125 million cubic meters of waste water per year. That is 343 million liters per day, or a quarter of a million liters per minute.

  • Other interests: The core responsibilities of the Water Authority are safe dykes and the provision of sufficient clean water. We are also responsible for open and safe waterways, improving nature reserves and recreational areas and maintaining the cultural landscape, so that people can continue to enjoy this beautiful part of the Netherlands.

Water Authority management

Water Authorities are run by a democratically elected management, led by a Chair. The General Board determines the strategy and is responsible for general management. The Executive Committee is responsible for day-to-day operations and implementing the General Board’s decisions.
