Designing for communities
Is drinking Rainwater innovative? It was probably one of the most ancient ways of surviving, but today with pollution and air contamination it has become dangerous. Thinking of sustainable solutions to water shortages in Mexico City, the team at Isla Urbana came up with a system designed to harvest rainwater and purify it.
Today, 36% of families in Mexico City do not have adequate access to water and spend up to 20% of their incomes to buy trucked water. United Nations
A team of young engineers, urbanists and ecologist decided to come together and develop a new industrial design system for rainwater harvesting: a blue tank collects and filters rainwater which is then pumped into a house. The household system is $1,100 for the complete installation and $150 annual maintenance costs.
The average harvesting in the city for a 60 m2 roof is 45,000 Liters (11,888 gallons) per year to harvest de average rainfall in the city of 750mm per year, which covers an average of 5 to 8 months of water needs. Renata Fenton, Director of Design, Isla Urbana
Beware of the “megacorte”
This will definitely be useful next week, when the public water service will be completely suspended for three days (this is the “megacorte” or “mega cute”). Starting 31 October 2018, 13 boroughs of Mexico City and 13 municipalities of México state will be completely dry. This is to allow maintenance and repair work on the Cutzamala pipe.
Earning trust for the future
So far, and after 10 years, Isla Urbana has installed about 8,700 systems, which provide water to more than 52,000 users. The kits are designed to provide different types of water quality (from water for toilets and washing up to purified water for drinking), for different types of buildings and roof sizes and for both the urban and rural context.
The real challenge now is to change the community’s perception of rainwater, teach them to trust the rainwater collected, to use it. Renata Fenton
Also, by storing increasing volumes of water, families can then become completely independent from unsustainable sources of water. The empowering nature of the benefit is crucial.
What makes this project so innovative is its realistic nature. Isla Urbana does not aim at solving the water issue in Mexico City in one day, it aims at providing solutions to everyday problems.
