Dutch Water Board Offers Up to €5,000 for Green Roofs and Rainwater Systems
Den Bosch, Thursday, 1 January 2026.
The Aa en Maas water board launches subsidies covering up to €5,000 per project for climate adaptation measures including green roofs, water retention systems, and rainwater disconnection projects. Property owners across eleven Dutch municipalities can now access funding for sustainable infrastructure that reduces flooding and drought risks while cutting water and energy costs. The initiative requires green roofs to store at least 30 liters per square meter and rainwater barrels to hold minimum 100 liters, with applications accepted up to six months before project start.
Comprehensive Coverage Across Multiple Municipalities
The subsidy program extends across a significant portion of the Netherlands’ Noord-Brabant province, covering residents in Asten, Bernheze, Boekel, Deurne, Gemert-Bakel, Helmond, Laarbeek, Maashorst, Meierijstad, Someren, and Oss [1]. Additional municipalities including ‘s-Hertogenbosch, Heusden, Sint Michelsgestel, Mierlo, and Land van Cuijk are also eligible for funding through separate application portals [1]. The water board has established three distinct online application systems to streamline the process: residents of the first eleven municipalities can apply through one portal, Land van Cuijk residents use a dedicated system, while all other municipalities within the water board’s jurisdiction access a third application platform [1].
Technical Requirements and Application Process
The water board has established specific technical standards to ensure project effectiveness and environmental benefit. Green roof installations must demonstrate a minimum water storage capacity of 30 liters per square meter to qualify for subsidy funding [1]. Similarly, rainwater collection systems require barrels with at least 100 liters of storage capacity [1]. Project applicants must submit detailed information including roof surface area measurements, specifications of any metal materials used such as copper, zinc, lead, nickel, or chromium, photographic documentation of current conditions, comprehensive project descriptions, and contractor quotes [1].
Broader Climate Initiatives and Regional Cooperation
The climate-resilient infrastructure subsidies represent part of a broader environmental initiative by the Aa en Maas water board. In 2026, the organization allocated €100,000 for biodiversity enhancement projects, offering 50% cost coverage up to €10,000 per application for landscape elements including insect and bee hotels, nesting boxes, stork nests, pond construction, shrub hedges, tree planting, and flower-rich grass mixtures [2]. An additional €200,000 budget supports recreation and education programs that increase water awareness and environmental consciousness throughout the region [2].
