At the beginning of every month, the caretaker of a small apartment block would pin the water bill on the noticeboard.

Almost immediately, the arguments would begin.

“I live alone. Why should I pay the same amount as a family of six?”

“I was away for two weeks. How could my water bill still be this high?”

“Someone must be using water without paying!”

The landlord had divided the main water bill equally among all the tenants. It looked simple on paper, but it was creating resentment, delayed payments and endless disagreements.

One tenant used water carefully. Another washed several vehicles every weekend. Some households had more occupants than others. Yet everyone received almost the same bill.

The real problem was clear: nobody knew exactly how much water each household had consumed.

A Meter Changed the Conversation

The landlord eventually installed prepaid water meters for the individual units.

From that day, every household could purchase water credit and consume water according to its own needs. Instead of arguing over estimates and shared bills, tenants could manage their consumption based on the amount of credit available.

The question changed from:

“Why am I paying for somebody else’s water?”

to:

“How can I manage my own water consumption better?”

That simple change restored fairness, improved payment collection and encouraged responsible water use.

Why Prepaid Water Metering Makes Sense

A prepaid water meter allows users to purchase and load credit before consuming water. This helps property owners and water-service providers reduce dependence on manual billing and follow-up collection.

The Dotmobi STS Prepaid Water Meter is designed to provide a secure and convenient approach to managing water consumption. It uses prepaid credit and complies with the Standard Transfer Specification—STS—for secure token-based operation.

The solution can be considered for:

• Residential apartments and rental houses
• Gated communities and housing estates
• Schools and institutional accommodation
• Commercial premises
• Staff quarters and shared compounds
• Community and private water-distribution projects

Benefits for Property Owners

Improved revenue collection

Water is paid for before consumption, reducing unpaid bills and repeated collection follow-ups.

Fair allocation of costs

Each household or user manages and pays for its own consumption instead of relying on disputed estimates.

Reduced billing disagreements

Clear consumption responsibility helps minimise conflicts between landlords, tenants and water suppliers.

Better water management

When users can relate consumption to available credit, they are more likely to monitor unnecessary usage and wastage.

Simplified administration

Property managers spend less time dividing bills, preparing manual statements and pursuing outstanding balances.

Benefits for Water Users

Prepaid metering is not only about collecting money. It can also give users greater control.

A tenant can decide how much water credit to purchase. A family can monitor its consumption habits. A business can budget for water more predictably. Most importantly, users are not required to carry the cost of another person’s consumption.

Do Not Let a Shared Water Bill Destroy a Good Community

The landlord in our story originally thought the disagreement was caused by difficult tenants.

It was not.

The real problem was a billing arrangement that could not clearly connect consumption to the responsible user.

Once the property adopted individual prepaid metering, the accusations reduced, payments became more organised and water use became everyone’s personal responsibility.

Sometimes, the solution to a complicated dispute is not another meeting.

It is better measurement.
