Rainwater tank Hambarita beside kitchens, improving health with daily clean water access
Rainwater tank Hambarita turns rooftop storms into safe water steps from home
Short rains can change a day when harnessed effectively. In Hambarita, we constructed Wai La Wurung, a ferrocement pot strategically located near kitchens, so that families are spared the long walk to collect water. The structure consists of rebar hoops and wire mesh, forming a thin yet robust shell (More info here). It features double plastering to prevent algae growth and a secure, lockable lid that safeguards the water within.
Gutters are installed to capture consistent rainfall, with downpipes guiding the water flow efficiently. A first-flush system is in place to divert initial dirty rainwater, while an overflow system leads to a soak pit that reinforces the base. Each joint was pressure-checked during commissioning to ensure it remained dry and intact. Caretakers were trained in essential maintenance tasks, including cleaning gutters, checking filters, and providing safe tap use.
This initiative exemplifies practical health solutions, backed by seventeen years of Swiss-led fieldwork and the dedication of local crews in East Sumba. Accessible water is a cornerstone of reducing infections, freeing up time for mothers, and enabling children to attend school regularly.
Thank you to the neighbours who transported the sand, the welders who secured the downpipes, and the children who learned essential maintenance skills. In collaboration with Fair Future Foundation and Kawan Baik Indonesia, we transform moments of rain into dependable
