Smart sensor data aids Bangkok’s with water loss prevention
Bangkok’s Metropolitan Waterworks Authority (MWA) processes and supplies an average of around 5.47 million cubic meters of water every day to over 11 million people. Water losses in the water supply system have always been a serious issue. As of September 2018, close to 30 percent of the water supply was reported to be lost through leakages in the pipeline network.
To overcome this challenge, the MWA needed to gather in-depth data from across the Bangkok water supply, so it decided to increase its install base of flowmeters. It has been using ABB AquaMaster flowmeters since 2007, and it increased the total number to over 400 with the help of ABB Channel Partner, Thai Meter.
The meters were selected for their durability and accuracy, and because they eliminate the potential for error from manual data collection. They transmit data using GSM-SMS radio technology when they detect a possible leak, providing an early warning to the MWA so it can immediately begin water loss prevention efforts. The project aims to cut water losses to 19 percent by 2021.
“To reduce water loss, the ABB flowmeter is one of the significant tools we use to provide high-resolution data that facilitates step testing, leakage detection, and water network analysis in the Bangkok Metropolitan area,” explains Mr. Supichete Tavorntaveevong, Director of the Water Loss Management department.
