The majority of water in Kibera is sold via overpriced and quasi-legal kiosks, while unlined pit latrines remain the primary sanitation facility. The resulting unsanitary conditions constitute a major health risk for residents. KDI partnered with Spatial Collective and Nairobi City Water and Sewerage Company (NCWSC) to pilot WATSAN Portal: Kibera, an innovative online mapping and decision-making tool that was designed to enable community groups, nongovernmental organizations, and government agencies to rapidly and efficiently launch high-quality water and sanitation projects in Kibera.

The project was funded by the Rockefeller Foundation and piloted in 2013 in two Kibera villages, home to a total of 100,000 residents. The development of the Portal's functions and user experience was based on in-depth consultation with NCWSC, NGOs, Community Based Organizations, and community partners. In total, over 51 individuals from 33 organizations were represented through 33 individual consultations and 9 formal group workshops.
