Gravity-flow systems in Karnali

Piped gravity-flow schemes carrying spring water to hill villages, maintained by user committees.

Karnali's springs sit above its villages, which makes gravity the cheapest pump available. The program engineers schemes that need no electricity: intake tanks at the spring, sediment traps, and tap stands placed so no household walks more than fifteen minutes.

Each scheme signs over its maintenance fund to the user committee before construction ends. Our engineers stay through the first monsoon — the season when badly built schemes wash out — and the scheme is only counted as reached after a full year of service.
