Tanka & Kund
Rooftop rainwater harvesting
Born in Rajasthan (Thar), pan-Indian.
How it works
Roofs and paved catchments funnel monsoon rain into sealed underground tanks for year-round use, survival engineering in low-rainfall zones.
In a modern home
Rooftop rainwater harvesting + storage, first-flush filtration, society-scale collection tanks (a strong Pada Apt feature).
