Drinking water performance


The Bureau uses similar regulation principals to those in the UK and US for network performance evaluation. All licensees who operate transmission or distribution systems are required to report regularly on their performance in respect of system security, availability and quality of service.

This information provides a picture of the continuity and quality of supply experienced by final customers. The performance report continues to incorporate year-by-year comparisons to help identify trends in company performance and to highlight areas where improvements are needed to raise the level of performance.

The quality of supply experienced by customers is influenced by the performance of each stage of water supply: production, transmission and distribution.

Key performance indicators

The Bureau developed, in consultation with the distribution companies, four technical key performance indicators (KPI’s):

  • interruption to supply;
  • pressure of supply;
  • type of supply; and
  • metering.

Another KPI, relating to the quality of the water distributed is included in the Water Quality Regulations and compliance with sampling and prescribed limits is measured by the Bureau.

The Bureau, in consultation with TRANSCO, identified and developed three technical key performance indicators:

  • unaccounted-for water;
  • availability of the transmission system; and
  • security of supply.

a) Unaccounted-for water

The net difference between the water dispatched from all the water producers at the defined entry points to the transmission ..

The net difference between the water dispatched from all the water producers at the defined entry points to the transmission system and the water delivered at the distribution exit points is defined as unaccounted for water.

The unaccounted-for water at the transmission system is mainly due to real and apparent losses. Real losses are the losses caused by physical leakage from the network. Apparent losses are the losses that are unmeasured (un-metered), errors in metering and illegal connections.

TRANSCO is required to produce a balance sheet on a monthly basis that shows the total monthly inflow to the transmission system from all the water producers including the change in the storage at the relevant regional transmission system. Then, the total inflow and the difference in storage are subtracted from the total outflow at all the connection points between TRANSCO and the Distribution Companies. This results in a figure for the total unaccounted-for water.
