                    The fact that somebody else has done it before makes, in many cases, the job of selling
                    an aggressive program and budget to an executive manager or board of directors more
                    feasible. The steps undertaken in a water loss control program are discussed and
                    reviewed in detail throughout this manual. The chapters are self-contained and do not
                    need to be used in order although an operator with no experience in progressive water
                    loss control methods is urged to read the entire book. The manual focuses heavily upon
                    the progressive methods pioneered in the England and Wales in the 1990s and transferred
                    widely on an international basis. It also consistently evaluates the more “traditional”
                    conditions that exist in North America, and other nations, where water loss has not
                    been a foremost priority. This is done to demonstrate that the need to proactively control
                    lost water exists in even the most developed nations, and that easily transferable
                    technology now exists to control water losses.
                       The manual includes sections that allow the reader to

                        •  Understand the nature and scope of water loss occurring in public water supply
                           systems
                        •  Learn about the latest analytical methods and tools
                        •  Assess water losses for any system by using a standardized water audit and
                           component based analysis of real losses
                        •  Follow through all steps of a successful water loss control (optimization)
                           program
                        •  Implement field interventions to control real losses
                        •  Implement field interventions to control apparent losses
                        •  Implement demand control
                        •  Perform cost to benefit calculations
                        •  Identify when and how to use a contractor or consultant

                       This manual is intended to be a hands-on tool for water system managers who are
                    motivated to understand the nature of water loss and take meaningful action to reduce
                    it. Its content provides a detailed road map for any water system operator to implement
                    a program that is the appropriate response for an individual water system’s needs.
