Leakage and failures of water distribution mains in the city of Al Ain, UAE
A large amount of water is lost from the Al Ain water distribution system due to pipeline breakages that may have links to socio-economic and environmental impacts. The numbers of line failures in the region are too high. This study is an overview of the types and failure factors affecting water lines. Methods of repair and rehabilitation are described. Three case study locations were investigated. The incidence of water line breakages is relatively higher in the summer. Pipelines in the study region are comparativ...
Case study - Germany/Eislingen - Permanent leakage monitoring is the fastest way to reduce leakage
The town of Eislingen in Southern Germany has practiced Active Leakage Control for many years with a team of two equipped with a ground microphone and correlator who drive around in a van searching for leaks. As many of the pipes are one hundred years they had a good success rate often finding leaks. With two hundred and forty kilometers in the network, there is a large area for one team to cover and the leak detection process is expensive, laborious and lacking strategy.The engineers at Eislingen have been...
Permanent Monitoring Systems for Seabed Leakage Detection
Seabed leaksWhere do they come from? Natural vents: Faults, Pockmarks, and Chimneys Melting hydrates Shallow gas layers Long term leakage along well casings (cracked cement) Injection: fault re-activation/fracturin Lost well control nd failing barriers The mysterious pockmarks at the Troll fieldFootprints from melted hydrate lumps (after the last glacial period)Characteristics of Seabed Gas LeaksMonitoring solution for Permanent seabed leakage detection in the vicinity of production facilities:Traces...
Electronic Water Meter For Leakage Repair - Case Study
Every year, EMS (Energy Management System) produces and markets smart electronic water meters (domestic/ bulk), wireless transmission data logger (GSM/ GPRS), and advanced AMR (Automatic Metering Reading) systems. Unlike traditional mechanical water meter, the magnet-free electronic smart water meter with class C (CNS 14866) metrological performance can maintain 12 years battery lifespan. With a tamper-proof design, it also has leakage detection function, flow directions, monthly water consumption log, and MNF...
Detection of Minor Leakage in a Drinking Water Power Plant Pipeline
Project in the South Tyrolean community Mals in ItalyThe final pressure test of a 2014 newly installed pipeline m a drinking water power plant in the South Tyrolean community Mals (Italy) showed a pressure loss out of range, which prevented the plant`s commissioning. Thus the company MTA Messtechnik GmbH has been tasked to identify the reasons for the losses as quickly as possible using its newly developed pipeline inspection system Pipe-Inspector. The decision for Pipe-lnspector was based on the ability of the...
