Figure 5 Service reliability. The results show that there were two systems that satisfied the reliability criteria; one under private operator management and the other under direct WSDB management. Generally, the results of the service reliability reveal other factors that affected the part- nership, some of which were external (technology, availability of alternative water sources) to the partnership. The system in Ate- bubu faced challenges due to the technology of the system, which was a relatively complex water treatment plant that relied solely on diesel powered generators. The Atebubu system only produced water when it had money to buy diesel to power the generators at the water treatment plant. Again it operated effectively for
