Smart water infrastructure
The Maji Community Dispenser is a solar-powered water point with prepaid NFC WaterCard payments built in. NGOs, community water committees and operators use it to turn water schemes that leak revenue into services that fund their own maintenance.

Figures as of August 2026
Metered and delivered through Maji Community Dispensers
Why operators choose Maji Systems
Prepaid tokens remove cash handling, credit risk and informal pricing. Every litre is metered at the tap and reconciled to your account the same day.
A built-in 14 Ah battery, charged by a 50 W+ solar panel through a regulated controller. Dispensing continues through network outages and syncs when connectivity returns.
The valve and flow meter are the two parts scheduled for routine replacement — every two years or 100,000 cycles — and both are available individually from the webstore.
Volume, revenue and maintenance data per site, with long-term trend graphs and data exports from the web dashboard.
MIFARE DESFire WaterCards with AES-encrypted data. Genuine NXP cards are rated for up to a million write cycles.
The same electronics and payment stack in a self-contained Standalone unit or a Flush kiosk installation, reporting into the same web dashboard.
How it works
We size the dispenser to your source, demand profile and tariff, and model the revenue before anyone commits to hardware.
A two-person team commissions each unit on a concrete pad. No grid connection, no trenching, no specialist contractor.
Customers tap a prepaid token and draw exactly what they paid for. Revenue lands in your account, reconciled automatically.
The dashboard shows volume, revenue and faults per site, so problems surface before a queue forms at a dry tap.

Case studies
GhanaGhana Water Limited (GWL) · Public utility standpipes
Ghana Water Limited (GWL) worked with Maji Systems to fit seven public standpipes across Kumasi with solar-powered, prepaid Community Dispensers, giving GWL a metered record of consumption at each site rather than a single unmeasured connection.

GhanaCommunity Water Committee · Rural community water
Existing standpipes across the Ashanti Region were fitted with Maji Community Dispensers, replacing informal cash collection with prepaid WaterCards and giving the village water committee a transparent, accountable record of every sale.
