Description
PlayPumps International installed merry-go-round handpumps intended to lift groundwater as children played, with maintenance funded by advertising revenue on storage-tank billboards. Backed by approximately $60M from the Case Foundation, PEPFAR, USAID, and the Clinton Global Initiative, thousands of units were deployed rapidly across South Africa, Mozambique, Zambia, and Eswatini starting around 2000, without long-term field testing. Spare parts and the repair hotline were centralised far from rural users, producing outages of up to 17 months. Ad revenue never materialised in rural areas with no advertisers, so the maintenance model had no funding mechanism in practice. Installation halted by 2009 and remaining inventory was transferred to other operators.

Lessons learned
- A device with no local-repair capacity, no nearby parts supply chain, and no viable revenue model reproduces the maintenance breakdown it was meant to solve — the failure was social and logistical, not technical.
- Centralising spare parts and the repair hotline far from users guarantees long outages; sites recorded outages up to 17 months.
- Designing maintenance funding around billboard advertising assumes paying advertisers exist in deployment areas; in rural southern Africa they did not, and the model never generated upkeep revenue.
- 63% of Zambian sites reported no community consultation before installation, and those communities did not take ownership of the pumps.
