Rwanda uses funnel-shaped roofs and underground ceramic tanks as a smart, eco-friendly way to harvest rainwater.How the System WorksFunnel Roofs: Inverted cone or funnel-shaped roofs catch rain over a large surface area.Central Spout: Rainwater flows down the funnel and passes straight through a middle opening.Underground Storage: Water goes into buried ceramic or clay-lined tanks.Why the Design HelpsClean Water: Local clay materials help filter out dirt naturally.Cool Temperature: Earth keeps the stored water cool and fresh in warm weather.Space and Safety: Underground placement stops evaporation and protects water from sunlight and bugs.Drought Help: Systems provide steady water during dry months.
