Rain Funnels

Rain Funnels reframes a simple question for Mexico City: why does so much rainfall go uncollected while the city faces a deepening water accessibility crisis? Designed by the studio SomePeople as a proposal for the Mextropoli 2019 festival pavilion, the project showcases the quiet power of passive water collection. A series of wooden frames hold funnel-shaped, machine-cut tarp collectors that redirect water into a small tank, turning a temporary structure into a working demonstration of an idea.

The concept rests on a fact that is easy to overlook. Mexico City receives millions of gallons of water from the sky each year, much of which never gets captured. By placing the pavilion in the central Alameda, the studio brings that overlooked abundance into public view, where festivalgoers can see harvesting happen in real time. The choice of a busy civic park matters: a pavilion is read by thousands of passersby, so its message has to land quickly and without explanation.

Why a pavilion suits this idea

Temporary pavilions are one of architecture’s most flexible formats. Free from the program of a permanent building, a pavilion can test a single idea at full scale and invite people to touch, walk through, and question it. That makes the type well suited to advocacy. Here the structure is not only shelter but argument, showing that low-tech tools such as tarps and timber can address a serious urban problem. The lightweight, demountable approach also keeps material use modest, an important quality for a piece meant to live for only a few days.

What gives Rain Funnels its staying power is the plan for what comes after the festival. The timber modules are designed to be repurposed into community centers and public spaces, where they would continue to collect water for irrigation. This second life answers a common criticism of festival architecture, that striking installations are built and then discarded. By treating rainwater harvesting as a civic resource rather than a novelty, the studio links a short event to a longer benefit for neighborhoods across Mexico City.

Projects like this show how a small, well-aimed gesture can shift public attention toward a resource hiding in plain sight, and toward the everyday infrastructure cities already have above their heads.
