The NWB Water Innovation Fund finances innovative projects of water boards that are broadly applicable and contribute to the sustainability of the Netherlands. The Dutch Water Authority Bank (NWB Bank) is the founder of this independent fund.

Which projects qualify?

The NWB Water Innovation Fund focuses on innovative and sustainable projects of water boards. This can include innovations in the areas of climate adaptation, climate mitigation, circular economy, biodiversity, water quality, water safety, and energy transition. Many of these projects face challenges in getting off the ground due to difficulties in obtaining risk-bearing capital. The NWB Water Innovation Fund was established to further support these projects beyond the so-called pilot phase.

Financial information

The NWB Water Innovation Fund provides equity or subordinated capital in the form of a loan. It always involves co-financing: the fund contributes a maximum of 50% of the total required risk-bearing capital, and at least 1/3 of the total required risk-bearing capital is provided by one or more water boards. The maximum financing contribution from the fund is €2 million per application.
