Water Loss and Leakage Management - Level One


1-day course

CPD Credit: 6.5 hours, C1 / C2

Course Overview

Leakage of water from the network is a serious problem on a national scale and that is reflected in every county across the country. Irish Water estimates almost half of the water produced is lost due to leakage within our water mains and within customer properties and is undertaking a national investment programme of works to reduce leakage and improve Ireland’s water supply. Reducing leakage will continue to be a key priority for Irish Water in the coming years.

Course Aim

This course will provide an introduction to leakage detection, control and management and the relevant technologies used to assist in the process. Trunk main and distribution leakage detection techniques where there is limited metering will also be covered in this course as well as an introduction to asset planning and District Meter Areas (DMA) design.

Course Programme

1. Introduction to Asset Management

  • Life of a pipe 
  • Reasons for failure

2. Introduction to DMA Design and Implementation

  • Reasons for a DMA
  • Benefits of a DMA

3. Basic Active Leakage Control Techniques

  • Leakage detection 
  • Factors affecting acoustics
  • Pressure and small leaks
  • Catastrophic failure
  • Successful Active Leakage Control

4. Driving Down Leakage: Localise, Locate & Pinpoint


  • What is Localise?
  • What are Noise Loggers?
  • How a DMA assists in localising losses
  • How to plan a Step Test


  • What is Locate?
  • What is a correlator?
  • Components of a correlator
  • Correlation theory
  • Common mistakes
  • How to minimise mistakes
  • Practical Exercise – Minimising errors


  • What is Pinpointing?
  • How does leak noise travel to the surface?
  • Manual listening stick
  • Electronic ground microphone

Learning Objectives

At the end of this course participants should be able to:

  • Demonstrate an understanding of leakage control processes and the technologies used in leakage detection activities
  • Analyse the causes of pipe condition failure and understand how pressure can cause breakages within the distribution system
  • Describe how DMA’s help to control and manage the distribution system
  • Develop the necessary skills and knowledge required to identify different types of leaks
  • Explain how the different technologies work and when is best to use them
  • Define the terminology used in Leakage Control Practices 

Who Should Attend?

This course will be of interest to engineers or technicians involved in the identification, location and evaluation of water leakage. Participants should be working with water assets in consultancies (as designers), Local Authorities and contractors involved in find and fix.
