A villager in Zimbabwe’s semi-arid Mangwe District has developed an innovative underground reservoir designed to capture and store water from a nearby stream, offering a lifeline for his household during prolonged dry periods.
Located in Msasane Village, the reservoir was built by Victor Dube, who says the project was inspired by the need to secure a reliable water supply for drinking and gardening.
Dube initially dug the reservoir about three metres deep and covered it, but soon discovered that the stored water was running out faster than expected. He then expanded the structure, creating additional space around it that could be filled with sand to improve water retention.
The sand also serves as a natural filtration layer, helping filter water as it enters the underground reservoir.
Dube estimates that the system can store up to 5,000 litres of water, with the supply potentially lasting between three and four months, depending on usage and rainfall.
For communities in Mangwe, where rainfall is often low and unpredictable, such locally developed water-storage solutions could provide an important buffer during dry seasons.
Dube hopes to further improve the system and use the stored water for both household consumption and small-scale gardening, demonstrating how simple, locally adapted innovations can help communities respond to water scarcity.
