The circular water authority

Sustainable way of working

The first steps have already been taken. We are increasingly working towards becoming a circular water authority. We are using fewer raw materials and limiting harmful effects on the environment. In our work, we consider costs, performance, risks, and consequences for people and nature. We make sustainable choices wherever possible.

Better for the environment and lower costs

For example, we are increasingly opting to renovate pumping stations, weirs, and flood defenses. Demolition and new construction are not always necessary. This costs less and is better for the environment. We also purchase sustainably as much as possible. Suppliers who ensure lower CO2 (and other greenhouse gas) emissions have an advantage when it comes to contracts and tenders.

Reuse of raw materials

We do not view raw materials as waste, but rather seek to reuse them. For example, dredged material can be used as a construction product. We can also recover energy and raw materials from sewage treatment. A good example of how we, together with partners, reuse raw materials and limit CO2 emissions as much as possible is the sustainable dike reinforcement project at Lauwersmeer.

Circular Noorderzijlvest Roadmap

Our water authority is already doing a lot in the field of circularity. Various studies and experiments are being conducted with renewable materials, such as bio-based materials and cement substitutes. You can read more about this in our Circular Roadmap. In this document, Copper 8 has provided insight into how we, as a water authority, can work (and design) in a more circular way.
