Our service area

Do you live in the service area of the Regional Public Water Authority Amstel, Gooi and Vecht? Then it is very likely that you live under the sea level. We are responsible for protecting you against flooding by maintaining a system of dykes, sluices and pumping stations. This system allows you to live, work and relax in safety.

Our service area covers parts of 3 provinces. The landscape is very diverse and has beautiful polders, lakes as well as cities. The area has various functions:

  • nature
  • recreation
  • city life
  • agriculture 

So many people, so many wishes

Approximately 1.3 million people live, work  and enjoy leisure time in our service area. They often have conflicting interests. We try to find the best possible solutions to meet everyone’s needs. And to manage the water in the best possible way. 

Are you at risk if the dykes break?

A large part of our service area lies below AOD, more commonly known in The Netherlands as NAP (Normaal Amsterdams Peil). On this scale, 0 refers to the average sea level of the North Sea. The lowest point of our service area is located in Polder Groot Mijdrecht, which lies 6 metres below NAP. It is one of the lowest areas in The Netherlands.

Are you curious if your home is at risk of flooding if the dykes break? And would you like to know what you should do in the event of a flood? The website (in Dutch) will help you to answer these questions. 

How do we protect you?

We protect you against waters in various ways. And we ensure that you have access to sufficient, clean and safe water. Our service area has:

  • 1000 kilometres of dykes, of which 570 km are secondary dykes along the rivers. These ensures that the polders remain dry.
  • 59 sluices.
  • Mills and pumping stations. Water is pumped out of the polders by 231 pumping stations.
  • 12 treatment facilities, where waste water is cleaned. Then the clean water can flow back to the surface water.
