How do we plan on protecting you against flooding in the coming years? And how do we plan to ensure clean, safe and sufficient water? Find out more about this in our 2016-2021 water management plan.

Keeping you safe

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

Clean water

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

The correct water levels

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

Climate change and the city

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

Water authority tax

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

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

Maps for waters and dykes

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.

Water authority by-laws

Each water authority has its own rules and regulations about the water and dykes. These define what you may and may not do in and around our water.

Water Act

The Water Act contains regulations for the use and management of water for the whole of The Netherlands.
