AquaPure SN — Solar Neighborhood Drinking Water

Network of autonomous solar drinking water kiosks in Dakar's peripheral neighborhoods, producing and selling purified water in sachets and jerricans at rates 60% lower than street vendors.

Environment
Complexity : Medium
Budget : $24,390 - $48,780
Problem

The Problem

Over 600,000 inhabitants of Dakar's peripheral neighborhoods (Pikine, Guédiawaye, Keur Massar) lack reliable access to running drinking water and depend on street vendors who resell water at 500-1,000 FCFA per 20 liters, 5 to 10 times the SDE rate. Women and children spend an average of 2 hours per day seeking and transporting water. The quality of water sold by vendors is often questionable, causing waterborne diseases that overwhelm health centers.

Opportunity

The Opportunity

Access to drinking water is a priority issue of the PSE and SDG 6. Solar purification technologies (reverse osmosis, UV, filtration) have fallen 70% in cost over 10 years, making autonomous kiosks economically viable. Similar models (Jibu in East Africa, WaterBoys in Nigeria) generate returns of 25-35% per kiosk. Dakar local authorities are looking for private partners to solve the water crisis in their neighborhoods.

The Concept

AquaPure SN installs 500-liter/day solar water purification kiosks in shared courtyards and neighborhood markets in Pikine and Guédiawaye. Each kiosk is managed by a local micro-entrepreneur (often a woman) trained by AquaPure and paid on commission. Purified water is sold at 25 FCFA per liter (500 FCFA per 20 liters), vs 50-100 FCFA from street vendors. Customers pay via Wave, Orange Money, or cash via NFC meter. An IoT sensor monitors water quality (pH, TDS, chlorine) and sends an alert if parameters deviate from WHO standards. An app lets users locate the nearest kiosk.

The "Secret Sauce" (USP)

  • Local micro-entrepreneur manager: the kiosk is managed by a neighborhood resident earning their living by selling water — immediate community adoption and 50% reduced operating costs vs centralized management
  • Real-time IoT quality monitoring: quality certificate displayed on each kiosk updated every hour — first water service with total quality transparency, a decisive argument against street vendors
  • Guaranteed 25 FCFA/liter rate: social contract with the community — AquaPure commits never to exceed this ceiling, building trust and loyalty from 600,000 captive households

Minimum Viable Product (MVP)

To get started quickly:

3 pilot kiosks in 3 shared courtyards in Pikine (500 liters/day each), 3 trained female micro-entrepreneurs, Wave NFC meters, IoT monitoring, tested over 3 months measuring satisfaction and consumption.
