Derby, UK: Pipeline inspection specialist JD7, a subsidiary of Aquam Corp, has completed the first training program for its advanced leak detection technology at the Metropolitan Waterworks Authority (MWA) in Bangkok. The five-days of training for the utility’s network engineers follows a successful water mains inspection project undertaken by JD7 in the Thai capital. MWA serves some 11 million people with mains water through a distribution network of over 32,000 km. The utility is deploying JD7 Investigator as part of its Water Loss Reduction Plan to reduce nonrevenue water (NRW) by identifying illegal connections and leaks. The company is currently running at 25% water loss and is targeted to reach 20% by 2017. JD7 Investigator is an asset management and leak detection tool which can be inserted into pipework through valves and fire hydrants at full mains pressure. The system can monitor real-time data captured by a CCTV camera combined with an acoustic hydrophone sensor head. Investigator allows MWA network engineers to better understand internal pipe conditions, leakage points and illegal connections.
