Supporting water accessibility in Luan

While high profile water transfer and conservation projects are helping to relieve the water scarcity challenges China faces as its economic success story continues, there is increasingly a movement towards identifying and implementing ways to drive efficiency in local water distribution and consumption in conurbations through improved monitoring and metering. In order to achieve this, the Luan Water Company opted to install ABB’s flowmeters in Phase 1 and Phase 2 of the city’s efficiency upgrade, optimizing its investment and ensuring operational efficiencies could be achieved.

Reducing water losses in city distribution network by 20% through smart solutions

In the city of Västerås, ABB is developing smart city solutions with multi-utility Mälarenergi to coordinate the operations of municipal water/wastewater, district heating/cooling and power systems, enabling them to operate as a unified system within a closed loop system. By integrating the control rooms of many operations into one unified operating environment operators can more easily collect, monitor and analyze data across all services to identify, categorize and prioritize potential issues with assets, processes, and risk areas. In doing so the city can optimize its production of water, wastewater, power and district heating networks with the aim of increasing efficiency, reducing energy use and non-revenue water.

Reliable water for Bangkok citizens

Efficiently maintaining a reliable water supply is a crucial task for the city with over 11 million people that consumes more than 5 million cubic meters of water a day – enough to fill 2,300 Olympic-sized pools. The drought is aggravating the water leakage issue that has been troubling Bangkok’s water distribution for years: due to leakages in the pipes throughout the distribution system more than 25 percent of the water is lost during transmission from the treatment plant to the households. A significant first step to meet this challenge of providing enough clean water is to effectively manage water leakage in the area. The Metropolitan Waterworks Authority (MWA), which produces and supplies drinking water in the Bangkok Metropolitan area, is relying on ABB digital technology to lower the disastrously high 25 percent level of water loss they’ve experienced.

Successfully safeguarding UNESCO World Heritage Centre and ensuring daily safety and security of local citizens and their businesses

The MOSE flood barrier system is a complex coastal protection infrastructure designed to block the high tides that regularly hit the Venetian lagoon, causing destruction to the city reliant on income from tourism to the World Heritage site. ABB has delivered an advanced automation system that coordinates the entire flood protection system, consisting of four flood barriers, multiple gates, navigation locks, and breakwaters to shield the lagoon from rising sea levels, winter storms and spring tides. It, in tandem with ABB’s 2600T series pressure, manages and monitors the raising and lowering of the MOSE flood barriers according to pre-set parameters, positioning the barriers at more appropriate angles to counteract the flow of the incoming water. In 2020 it was put into operation for the first time during stormy weather conditions, with water levels reaching over 4 feet peaks. In the past these levels would leave around 30 per cent of the Venice submerged under water, however the barriers worked efficiently, and the city remained dry.
