Stage 1 · €10,000reached

800 people · 1 water point · 4 latrines

The drilling to 80 metres and the water test: a laboratory analysis in Niamey before the well opens. The same stage builds the first four latrines beside the neighbourhood's school, so the well serves 800 people from the start.

Stage 2 · €6,000€5,085 of €6,000

adds 400 people · 6 latrines

The solar pump and the 20,000-litre tank: water stays available through the dry season, when the old well's level drops, and reaches 400 more people. Six new latrines in the yards of the families furthest from the tap; the panels and the pump carry a five-year warranty.

Stage 3 · €4,000the plan ahead

adds 4 handwashing stations

The four taps across the neighbourhood, each with its handwashing station, and the training of the water committee the residents elect (half of it women) and of the two technicians who will do the routine repairs.
