CONTEXT

Most public utilities not operating efficiently in Africa

High Unaccounted for Water (NRW) Low Cost recovery Low Tarrif levels High staff per 1000 connections Availability of supply

Performance Indicators and Benchmarking

Benchmarking is the search for industry best practices that lead to superior performance.

- Robert C. CampIt is understood as the process foridentification, understanding andadaptation of remarkable practices andprocesses of other organizations to helpthe improvement of its own performance

BENCHMARKING has been used as a toolby the water sector industry over the lasttwenty years

CONCEPTS OF BM FOR Utility

Better service qualityHigher resources productivityHigher satisfaction by ConsumersHigher general return for thecompanyEnvironment improvementBasically higher operationalefficiency

6

Humility to accept that there may be otherCompanies with a better performance butunder similar socio-economic environment

Wisdom to learn the changes that may arisefrom comparison

Ambition to introduce the necessary actions Effectiveness to accomplish the programmed

goals

The BENCHMARKING ProcessRequires:

IWA Benchmarking initiative

The objectives of the initiative was to: develop generally accepted procedures and methodologies able to provide decision makers with an overall perception of the utility performance as a sound basis for making strategic choices. Clear definition of a reference framework for Performance Indicators and Benchmarking methodologies, as well as adequate models of aggregation that fit the basic needs of the key types of user.

IWAs motivation

Demand from IWA members for guidelines on Performance Indicators

the definition of a common reference for PI that fits the basic common needs of the key types of users in the Water Industry

Main target users: the utilities themselves.

Output

A standardised PI language, covering:

syntax (structure)morphology/semantics (vocabulary and definitions)

etymology (from data to PI)
