WATER METER

This was divided into 3 Parts:
1) ensuring that all household connections were metered;
2) the selection of water meters with high efficiency and acceptable quality; and
3) the introduction of a monitoring and replacement program. In 1993, 12.61% of all water connections had water meters, resulting in most water bills being calculated based on assumptions. In 1994, PPWSA commenced installing water meters to all household connections and ceased calculating water bills based on assumptions.

-The below graph shows the annual increase in watermeters compared to the number of connections. From 2001 onward all household connections were metered.

- In order to improve the accuracy of the water meters in 1997, PPWSA commenced replacing the old Class B meters which had a low accuracy and a bias rate more than +/- 8%, with Class C meters, which had higher accuracy and a bias rate of +/- 2%.

- The final measure in the management of water meters was a program for monitoring the replacement of meters. The longer the meters were in service, the higher their bias rate was found to be. Accordingly, in 1994, PPWSA established expert offices to regularly monitor and replace the meters according to standard operating procedure.
