From ‘Entrepreneurs in Mexico City Turn Water Risk into Opportunity‘ by Paul Reig.

Mexico City, the biggest metropolis in the Western hemisphere, faces significant water shortages, leaving many domestic, agricultural, and industrial users exposed to severe water-related risks. The city was built on the foundations of the Aztec capital, on the bed of Lake Texcoco. Today, centuries later, its groundwater supplies are rapidly diminishing, and it relies on a network of reservoirs and decaying infrastructure to pump in water from hundreds of miles away. Furthermore, urban growth and climate change are pushing Mexico City’s water supply to the edge. Reservoirs were dangerously low during the 2009 drought, leading the government to cut off water in some areas of the city.

While the situation in Mexico City is undeniably alarming, these risks can also create new opportunities for businesses to prosper by delivering innovative solutions to water scarcity. In 2012, four entrepreneurs in Mexico City founded Sistemas de Captación de Agua Pluvial® (SCAP®), a company providing rainwater harvesting solutions. Harvesting rainwater and storing it for later use is an increasingly popular solution to unpredictable and limited water supplies. From a backyard rain barrel for lawn watering to the massive network of rainwater storage tanks that China’s Gansu province uses to provide drinking water to 1.3 million people, rainwater harvesting is being used in a wide range of scales and geographies.

SCAP helps its clients in Mexico overcome unreliable and limited water supply by designing and installing efficient, affordable rainwater collectors. SCAP has already completed a project in Colonia Florida and is planning additional installations in El Pedregal and Mixcoac. By collecting rainwater, SCAP clients can cut back on the cost of water and store freshwater for times of shortages. To better understand water-related risks in Mexico City and how they compare to the rest of the country, SCAP used a preview version of Aqueduct’s forthcoming improved global water risk maps. Aqueduct’s granular and comprehensive maps of water scarcity, supply variability, and groundwater stress (among other indicators) helped SCAP target and inform clients in central Mexico on areas most in need of solutions. Having this up-to-date data in a widely accessible format allowed SCAP to turn water risk into business opportunities—in turn, helping Mexico’s citizens meet their water needs. […]

Public Rainwater Systems: Childrens’ Playground

The new development by Aspect Studios at Darling Quarter in Sydney recently featured on the InDesignLive website.  At the heart of the site is a children’s playground with heaps of things for kids to play on, climb up or mess around with.  At ground level there are stepping stones of various heights, looking much like tidal pools along a beach, and there’s an enormous rope climbing frame.  Site-harvested rainwater irrigates the playground and the surrounding public parkland, and is also used in the industrial-looking water features from Germany.  Low-energy lighting is used for night lighting.

The harvesting systems and related quality controls for the use of rainwater on this public site must be quite highly resolved – does anyone know of other examples (especially in Australia) where rainwater is used for play as well as for irrigation?  KA
