Prepaid Water Meters

Waterwatch supply, rent and manage SABS approved prepaid water meters of the best manufacturers available in South Africa.

The Standard Transfer Specification (STS) technology enables consumers to buy prepaid water at the same retailers or on the internet as is done with prepaid electricity. Automatic Meter Reading (AMR) technology ensures that consumption and meter data is retrieved on a regular basis for meter management as unattended meters will lead to losses.

Waterwatch has developed cross supplier management solutions that ensure property owners remain in control of water consumption and recover funds from consumers.

Waterwatch Features

Innovation in pre-paid water meter systems

Prepaid Water Meters


The wall mount or external prepaid water meter is installed by a certified plumber under supervision by Waterwatch at the main connection to the house or unit.

Access must be arranged for the Waterwatch representative to install the keypad user interface inside the consumer’s building. The keypad is linked to the meter by the representative.

The prepaid meter is registered on the Waterwatch vending system and is now ready for activation.

After installation, the parties will agree on an activation date when all the meters will be activated.


Buying Water

You can buy water from any shop or vendor that sell prepaid electricity for example, Engen garages, Pick & Pay, Spar etc. Ask for “Prepaid Electricity” or “Prepaid Water” and provide your meter number. Your meter number is normally printed on your keypad but you can also press #0# on the keypad to retrieve it. You will receive a 20-digit token which must be keyed into the keypad.

You can also buy “Unipin” vouchers from vendors or ATM’s. Select “Prepaid Electricity”. Follow the steps on the printout.

You can also register your meter on internet banking. See guidelines below.

Water is sold in kilolitres (kL) at the current tariff structure of your municipality

1 kL = 1000 litres = 1 m³ (cubic meter)
