Utility Systems Prepaid Water Meter

The WMD can be configured to:
> Dispense between 10 – 50 000 litres of water; at two scheduled times daily; thereby providing
the ability to limit a consumer to a finite (or negotiated) level of supply. This is especially
useful in the case of low income consumers who may never be able to afford to pay for water;
but nonetheless have the right to recieve a basic level of service.
> Be linked to a fixed (flat rate) tariff to provide consumers with the option to voluntarily limit
consumption according to their budget. As with the free basic water allocation; this facilitates
budgeting not only by the individual consumer; but by social service agencies; government
departments; and NGOs
> Provide meter readings by radio signal or the global system for mobile communica?ons
(GSM) to a drive-by or walk-by collector; or through a fixed network
> Operate at a reduced daily or monthly quan?ty; this is very useful in managing problema?c
customers
