ABB digital control and monitoring technologies fortify Ho Chi Minh City’s aging water distribution system
Ho Chi Minh City has transformed from a simple economy based on fishing into the economic heart of Vietnam and the country’s largest city in just 50 years. Such a major development also brings economic growth for the entire country. However, it also threatens the rapidly aging urban infrastructure, including the city’s water network. The city lost nearly 30 per cent of its clean water in 2016 through leaking and damaged pipes. More than 150 million cubic meters of water went to waste last year.
In order to keep up with the rapid pace of urbanization and meet the target of reducing the water leakage to only 10 per cent by 2020, the local utility Saigon Water Corporation (SAWACO) recently undertook a major renovation of the city’s water distribution network. To meet this complex target, a strategic ABB AbilityTM Symphony® Plus SCADA system has been designed. The ABB system integrates a sophisticated leakage detection and management system from the water network management company TaKaDu.
ABB Ability Symphony® Plus is a distributed control system (DCS) especially tailored for the water and power industries. Part of the ABB AbilityTM portfolio of digital offerings, this control system adds value for customers by carefully collecting, analyzing and providing actionable insights on plant and engineering data in their systems, ultimately allowing them to lower project risk, reduce cost and throughput times and improve asset performance and profitability.
The project will deploy several data collection points, such as sensors and meters for flow and pressure monitoring, to the water network and allow SAWACO to digitally monitor the network conditions in “nearly real time”. ABB’s scope of supply for this critical project includes field instrumentation and sensors that are critical components to deliver high quality data to the control system.
With the digitalization of its network, real-time knowledge of network conditions and the accurate detection of leaks, SAWACO will be able to increase the amount of water delivered to households and industries. Moreover, it will also minimize the estimated 500,000 cubic meters of non-revenue water lost per day.
Since its launch in 2011, ABB AbilityTM Symphony® Plus has achieved more than 6,800 new installations, on top of the thousands of plants that have chosen to upgrade to this DCS. Symphony Plus is the DCS of choice for other projects in Vietnam such as the original commissioning and further extension of the Vinh Tan 4 supercritical power plant. Upon completion, the complex will provide an additional 5,600 megawatts of electricity to the Vietnamese national grid.
