Wai Pa Luri Wangu rainwater tank for Hambarita health and daily life
A 5,300 litre ferrocement tank that turns short storms into safe water
The Wai Pa Luri Wangu rainwater tank, a 5,300-litre ferrocement marvel, transforms short storms into a reliable supply of safe water for Hambarita. This achievement, carried out by Fair Future and Kawan Baik Indonesia, represents a cornerstone of primary healthcare, directly within the villagers’ yards.
Built with the assistance of local communities, the tank’s sturdy walls are made from bent steel, mesh, and layered cement, designed to withstand heat, shocks, and the intense monsoon cycles. The smooth plaster inside and outside minimises biofilm formation, ensuring the rainwater stays safe for drinking, cooking, and washing. A first flush and screening system efficiently removes dust, ash, and leaves, keeping the water clean. Overflow is directed to a soak pit, maintaining dry paths and preventing accidents as villagers carry loads.
By repositioning the tap close to kitchens and washing areas, women, elders, and children save several hours weekly, avoiding hazardous motorbike rides with jerrycans. This system reduces reliance on costly tanker water, allowing families to allocate more resources to food, seeds, and education. Community ownership is strengthened through regular cleaning, gutter maintenance, and system inspections. Thus, this project exemplifies preventive medical work by providing home access to clean water, reducing illnesses such as diarrheal diseases and skin infections, and even preventing fractures before clinical intervention is necessary.
