Article about the project 'Sterke Lekdijk' in the Netherlands which is part of the Flood Protection Program (HWBP). The primary barrier no longer meets the new safety standards in the Water Act and will be reinforced over a length of 55 kilometers. The 'De Stichtse Rijnlanden Water Board' (HDSR) wants to engage three parties for the reinforcement of the Lekdijk. They will work together according to an innovation partnership. The aim is to carry out the improvement without emissions.
