Background of the assignment: In one of the most low-lying and – with 1.2 million inhabitants and 40,000 companies on 41,000 hectares – most densely populated parts of the Randstad, Delfland ensures dry feet and clean and healthy water. We work with residents and businesses on a climate-resilient and pleasant living environment. In recent years, Delfland has made significant strides in preventing waterlogging, greening the living environment in and around water, and improving water quality. The Netherlands has been shaped by water and human effort.

Throughout the centuries, our country has been adapted to withstand the vagaries of water. Dikes were built collectively and were characterized by consultation, consensus, and compromise with area partners and residents. Delfland optimally utilizes this historical strength in exercising its care for the habitability of the land and the protection and improvement of the living environment. To this end, the water board is at the heart of society and continues to seek optimal societal impact.
