Our tasks

Large parts of our service area lie below sea level. The water authority protects you against flooding by maintaining the dykes.

We treat waste water to ensure clean water in our service area. We do this for recreational and agricultural purposes and to benefit nature.

Water authorities ensure there is sufficient water in the right place. Too high or too low water levels can cause problems.

Short periods of very heavy rainfall occur increasingly often, leading to problems in the cities. We are working on smart solutions.

Water authority tax pays for flood protection, treatment of waste water and proper water levels in the polders for nature and agricultural uses.

Regional water plans describe how the water authority manages all aspects of water in a particular area. For example, a polder or a lake.

The 'legger' consists of a collection of maps that show all of the surface waters and dykes in our area and who is responsible for maintaining them.
