Modernising prepaid utilities at Fumba Town, Zanzibar

EMA replaced token-based prepaid metering at Fumba Town with a smart-metering platform that delivers tokenless mobile-money recharge, real-time monitoring, and offline-resilient operation for the developer CPS Africa and operator Town Operations Company.

Fumba Town, Zanzibar
Challenge

The problem

In the token era, residents had to physically buy and key in recharge tokens, which meant queues and friction every time credit ran low. The operator had little real-time visibility into balances, consumption, or meter health, making losses and faults hard to detect. And because the system depended on connectivity at the point of sale, internet outages could interrupt the ability to keep meters topped up.

Solution

What EMA did

EMA deployed a smart prepaid metering network with estate-wide coverage across the development. Recharge is fully tokenless and tied to mobile money, while a central platform gives the operator real-time monitoring of balances and meter status, and an offline-resilient edge keeps recharge and metering working through connectivity gaps. The same platform runs electricity today and is ready to extend to water.

Results

The outcome

  • Tokenless recharge - residents pay by mobile money and credit reaches the meter automatically, with no tokens to buy or type in
  • Real-time visibility - the operator can see balances, consumption, and meter health across the site from one platform
  • Offline resilience - recharge and metering keep working through internet outages thanks to the edge-resilient design
  • Estate-wide coverage with no per-meter hardware that scales across the development and is ready for water
