Telvent's Advanced Water Leakage Detection Saves Millions Of Gallons Of Water Yearly
By Ivan Nazzaretto, Telvent Solutions Manager
Water loss is a major concern for most water utilities worldwide, as it affects not only operational processes but also impacts the financial, social, and environmental aspects of the utility. A 2006 report published by the World Bank declares that the total cost of non-revenue water (NRW) for water utilities worldwide can be conservatively estimated at $14 billion per year, with two thirds of it occurring in the developed countries.
Water losses can be classified as real (physical losses) or apparent (economic or commercial losses). Real water losses reflect water lost from the network and not used; these losses result from leaks in the distribution system, overflows from reservoirs, washouts, etc. Apparent water losses reflect water that is actually consumed by users but unmetered, or not correctly metered, and consequently unaccounted for. Here, we refer primarily to real water losses, focusing on the detection of leaks (or leakages) in transmission and distribution mains where most network water is physically lost.
In this paper, we discuss how Telvent’s Leak Management solution integrates with the enterprise SCADA system and uses the system’s real-time data to promptly identify the presence of leaks or bursts and minimize costs and other adverse impacts for the utility.
