One of the simplest, cheapest, and most practical solutions to flooding is something we often overlook: retention ponds . These man-made basins hold water permanently and manage stormwater before it wreaks havoc in our communities. And unlike mega- infrastructure projects that take years and billions of pesos, retention ponds are so easy to build that even our barangays can do them. In other words: Why aren’t we building more of them? A retention pond slows down stormwater, traps sediments, improves water quality, and prevents erosion downstream. It functions like a community-level buffer against the increasing intensity of rainfall we experience due to climate change . Unlike detention ponds —which dry out between storms—retention ponds always contain water. They look like real ponds, with vegetation around them, attracting fish, birds, and other wildlife.
