Application
1.Prepaid meters are cost-effective solutions to sustainable water
management in that they have a low cost of acquisition and, by
curbing water usage; capital recovery is possible within months.
The systems are also able to distribute water equally, based on
free water quotas, water balancing and fluctuating demand.
2.Aside from their ability to alert municipalities to leaks,
prepaid water meters also drastically reduce government’s admin
costs. This is because municipalities don’t need to chase bad debts
or budget for legal fees on unpaid accounts. Public sector cash
flow is immediately improved
3.Collecting data from prepaid meters is also more efficient than
the manual collection required for post-paid meters. A radio link
receiver can be fixed, vehicle-mounted, or carried by municipality
personnel
4.Prepaid metering reduces admin to a minimum, while removing the
risk and frustration of late or non-payment of water bills. This is
why housing estates are swiftly moving to prepaid water, as they
did with prepaid electricity. Gone are the days of splitting the
entire estate’s water bill by the number of units.
5.Prepaid metering means that users pay for their consumption only.
