Your Waterscape
To ensure an adequate supply of clean water in every season, Noorderzijlvest Water Authority has installed more than a hundred locks, weirs, pumping stations, coupures, and treatment plants in our region. Each one serves a specific purpose and is a familiar feature of the landscape for many residents. But what do they actually do? You can find more information on this website.

Cycle or walk in the Waterscape
In our region, you region follow various cycling and walking routes. The routes highlight our beautiful natural surroundings and water-management work in our region. They also help you better understand how we work to ensure safe water and the role the water authority plays in our daily lives.
