Buried pipes and drains occupy the ground beneath our feet unnoticed. But here, they emerge above the surface. While this invisible, complex and sprawling network plays a major role in rainwater drainage and management, it also limits the space available for urban tree planting, instead hastily carrying precious water away to treatment plants and outlets.
With its series of emerging, planted pipes, L’eau sous nos pieds aims to raise awareness about runoff water management in our cities. Water is often viewed as waste—something to be disposed of as quickly as possible. But it can also be retained and infiltrated into the ground to replenish groundwater reserves. Limiting the amount of water flowing through pipes and into treatment plants also helps to ease frequent flooding while preserving a precious resource.
