Audit of Non-Revenue Water (NRW) management within Bahrain’s Electricity and Water Authority

Technical and methodological audit of the NRW managment service
Recommendations and investment plan

4 180 km water networks

 

Context

The Kingdom of Bahrain is a country where potable water mainly comes from desalination and is hence costly to produce. Water distribution over the whole country is ensured by the same network which comprises about 3,700 km of mains in 2006 and grows to 4,180 km in 2020. The network is characterised by low pressures which rarely exceed 2 bars.

Altereo assists the Electricity and Water Authority to evaluate its performances in terms of Non-Revenue Water (NRW) management.

Altereo’s is distinguished in two distinct projects:

  • the first project carried out in 2006
  • the second project carried out in 2019-2020

 

Project Description

The first project consists of the following phases:

  • Technical and methodological audit of the waste control unit
  • Feasibility study for remote network monitoring
  • Benchmarking of different leak detection technologies including gas

This project produces a series of strategic recommendations for EWA.

The second project consists of evaluating the actions undertaken by EWA and the stages reached in order to continue to improve performances.. It consists of the following phases:

  • Preliminary audit of EWA’s achievements and performance since 2006
  • Non-Revenue Water deeper audit to investigate the previous findings
