    Type: Green roof with PolderRoof®

    Completion: 2018

    Client: VvE’ s Gravenloo, Gem. Leidschendam-Voorburg, Hh. Delfland

    Partners: The Dakdokters

    Location: Spinozalaan, Voorburg

    Surface water collection: 1400 m2

    Water storage: 60,000 liters

    Dynamically controlled: yes

    The VVE ‘s Gravenloo has replaced over 1300 m2 of tiles on the low roof of the parking garage for a green roof with controlled water storage below. With this water storage, flooding is prevented and the plants are supplied with water during dry periods. The roof is equipped with two Smart Flow Controlls; they measure the weather data and automatically adjust the water level.

    The municipality and the Water Board of Delfland want to improve the water management, ecology, and heat resistance of the area and thus make the city climate-proof. Immediately after delivery, residents of the flat were already enthusiastic, that can only get better once the plants start to grow!

    “Such a solution as the PolderRoof, that’s what the water board is all about.” – Marcel Houtzager (Hoogheemraad Hh. Delfland) at the official opening

    Delivering clean water efficiently and safely has become a world-wide problem. Water is lost due to leakages and ageing networks. We need to improve the distribution of clean drinking water from source to tap. We will work towards these goals by raising the quality and performance of high-pressure water distribution networks, improving safety levels of indoor drinking water supply, and building towards a new (smarter) ways of managing drinking water.

    Wavin Solutions for Rainwater

    Rainwater

    Climate change with massive rainfall, extreme heats and droughts put pressure on cities. Growing populations increasingly ask for greener living space. We need to (re)act to climate change and build livable and loveable cities. We will work towards these goals by creating integrated rainwater management solutions, countering the risk of flooded streets, avoid urban heat stress, and support greenification of cities. Our Wavin solutions already contribute.
    Wavin Sewer Solutions

    Sewer

    Millions of people have no or limited access to sanitation facilities. Simultaneously, ageing and poorly designed sewer systems contaminate groundwater resources. We need to future-proof wastewater transport and make sanitation accessible for everyone. We will work towards these goals by building sewer systems with modern technology, preventing leakages, corrosion and clogging of sewer systems, and boosting renewal of sewer infrastructure.
