Rainbeer co-founder Joris Hoebe created the motto: “No rain, no beer!” and
cleverly named his beer Code Blond, which also refers to the color-coded
Dutch weather forecast indicating dangerous weather such as storm, snowfall
and heavy rainfall conditions.
Hoebe was inspired by Dutch breweries in the Middle Ages that were set
up near churches and cathedrals to catch rainwater runoff from their roofs
to make beer. He worked with students and researchers from MediaLAB
Amsterdam, the start-up development initiative of the Amsterdam University
of Applied Sciences, to set up rainwater collection tanks on college grounds to
gather the secret ingredient for brewing his beer.

Rainbeer has since set up rainwater collection tanks elsewhere in the city,
including the hotel Volkshotel and gardening company Intratuin, scaling up
operations to make not just beer but also a special gin tonic, and possibly even
ice cream and soup in the near future.
This is one example of a small but innovative solution that has come out of
the Amsterdam Rainproof Programme, as shared by its programme director
CLC Researcher Michelle Chng visited Amsterdam where CLC’s executive director Khoo Teng Chye presented Singapore’s resilience initiatives at the Resilient City Leaders Forum (Amsterdam International Water Week 2017). As part of the week’s activities, delegates toured sites of the Amsterdam Rainproof Programme and were hosted by its director Daniel Goedbloed (centred). Source: Michelle Chng
The Amsterdam Rainproof Programme was started in 2014 by Amsterdam’s
water utility company, Waternet, in an effort to climate-proof the city against
extreme rainfall. Under this programme, Waternet works with stakeholders to
carry out city-wide interventions to capture every drop of rain and reduce the
risk of flooding.
Shortly after the programme’s introduction, the city experienced an extreme
rainfall event in July 2014. Some 90 mm of rain fell within a few hours,
damaging houses and slowing traffic as tunnels filled with floodwater. This
event increased the city’s urgency to climate proof urban areas, and catalysed
Waternet to roll out its surface solutions before underground sewers reached
carrying capacity. With an initial two-year budget, the team worked with the
municipality and various stakeholders to raise awareness and get people to
adapt to climate change and heavy rainfall.
Besides Hemelswater, other creative solutions that have emerged include a
gravel playground and porous parking lots at Mirandabad, which both enable
rainwater to be collected in crates beneath, saving the need to construct
new sewers. Another example are “polder roofs” that store rainwater for
irrigation or to be drained away at a later time. Most of such initiatives were
funded by the programme’s initial budget, the city’s Delta tax (which funds
the programme to protect the Netherlands against flooding and to secure
freshwater) as well through existing policies such as school-building subsidies
for green roofs.
This playground at Mirandabad allows rainwater to drain through the gravel-filled ground and into an underlying water-permeable canvas of geotextile and water collection tanks, which will drain to a well when necessary. Source: Michelle Chng
As cities worldwide look for ways to adapt to the new challenges brought on by
climate change, the Dutch have proved that solutions do not have to be largescale. They can come from simply re-thinking traditional methods and even
injecting a sense of fun!
