Application

Rainwater Harvesting Storage Tanks are essential components of decentralized water systems. They are used to collect and store rainwater from rooftops, catchment areas, or surface runoff, reducing dependency on unreliable water sources.


Tanks can be made from a variety of materials plastic, ferrocement, metal, or locally available alternatives and vary in size from household to community-scale. These systems are particularly effective in areas with seasonal rainfall, helping to buffer against drought and water scarcity.


Stored rainwater can be used for household needs, irrigation, sanitation, or livestock watering. They also support groundwater recharge when integrated with appropriate infrastructure. As part of integrated water management strategies, these tanks enhance climate resilience and promote water self-sufficiency.
