Waterproblems find their solutions
Fossil fuel dependency
There is a strong dependency on fossil fuels.
The Rijnland water authority decided to be carbon neutral in 2025 by reducing the emissions from fossil fuels.
Blue Energy Katwijk
Blue Energy uses the difference in salinity between fresh and salt water to generate renewable energy. In Katwijk, polder water, drainage water from the WWTP and seawater is used. Due to the improved mixing of fresh and salt water, the bacteria living in the fresh water die. As they do not longer reach the beach of Katwijk, the swimming water quality improves.
