In densely populated urban areas there is sometimes hardly a space to build new communal water kiosks, Prepaid standpipe are then an option. They hardly need space. The solar panel is build on top of the standpipe casing, which has an invisible locking mechanism and can only be opened with a special key.
In urban areas we also see there is a big interest in prepaid meters for individual connections, though water service providers are sometimes scared away by the relatively high costs. Yet, the advantages are many (no water meters required, no billing, upfront payment and no need for disconnecting/reconnecting clients that don’t pay. The return on investment for these meters is 6-12 months if the meters are used for clients with bad payment records.
