    About

    Common challenge

    Cities and densely built areas in the 2 Seas must adapt to more frequent intense rainfall and increased risks of urban flooding. Traditional public investments in drainage and sewage infrastructure cannot solve this challenge due to financial and spatial constraints. Local (water) authorities must resort to alternative, innovative solutions that integrate smart adaptation features in public and private spaces and buildings across their territory. Moreover, local stakeholders must become prominently involved in the implementation of those adaptation measures in and on their own properties.

    Main Achievements

    Agniesebuurt, in Rotterdam, will be made climate proof. The ambition is to capture, store and/or infiltrate the rainwater locally The measures must lead to sustainable water management, improved water quality, a pleasant living environment and greater social cohesion. The presented measures have led to resistance under the inhabitants. For this reason, the partners have launched the Expert Table. All stakeholders, including inhabitants, are representatives in the Expert Table. This resulted in a better atmosphere, and hopefully more cooperation of the inhabitants and stakeholders with this joined problem of climate change and challenges.
    In 2018, Leiden-in coop with Regional Water Authority Rijnland (Observer partner) - organized workshops with 30 city and national stakeholders. The result: a new project “the most sustainable kilometer of the Netherlands” (www.duurzamekilometer.nl) nearby Central Station, a dense compact urban neighbourhood. Together with these partners, Leiden signed a Green Deal to collectively work on a series of innovative projects such as innovative water storage and re-use on roofs. In the region of Westland, Delfland and Westland cooperate with inhabitants and businesses to create a more adaptive living environment. We attempt to increase the ability of our region to absorb and hold the water where it falls. In March 2018, Maxima, queen of NL, has done the honors of opening the World Horti Center (WHC) in Westland. On the side of the WHC we have implemented a couple of climate adaptive measures, e.g. permeable paved parking spots, an infiltration trench and a swale. During this opening event those measures were tested on effectiveness and efficiency led by a university professor and a group of his students. In November, we organized a Rainlevelr event. It was visited by 130 horticulture companies who all heard about the current developments of Rainlevelr and the plans for the future. At this moment the rainwater of 40 hectare glass is connected to Rainlevelr which means a capacity of 4.000m3 water storage. Southed-on-Sea and Essex were the excellent hosts of the Mid-Term Conference and really made the Conference and accompanying partnermeeting a great succes. This was a great publicity moment. Essex managed to be ready in time for the Mid-Term Conference with opening 2 (out of 3) subareas of their pilot, the raingardens in Basildon Hospital. Essex has finished their project of the raingardens in Basildon University Hospital in 2018.
