According to estimates from the World Bank, a staggering 45 million cubic meters a day is estimated to be lost globally through leakage: an enormous quantity that must be replaced, treated, and pumped again, to maintain supplies to customers. Eliminating leakage is therefore vital.
ABB’s end-to-end digital solutions are helping the local water authority in Karnataka, rural India to track, measure and optimize water use. The population of the Koppal district is 1 million and faces regular water shortages. The challenge in Koppal was to accurately measure water flow and use digital technology to integrate measurement and track water usage, but also leakage. The ability of AquaMaster to detect even very small variations in flow has been crucial in combating the water shortage challenges in the Koppal district.
In the Middle East where water stress is most pronounced, use of ABB AquaMaster flowmeters have helped cut leaks in the distribution network of Riyadh, by a staggering 40%. The sprawling city of Riyadh stretches over an area five times the size of Paris. In the past up to 60% of the cities water supply disappeared through leakage in the 6000 miles of pipe that supplied the population. OIML certification ensures that high accuracy standards are met. When combining this with low maintenance and reliability of the WaterMaster and AquaMaster flowmeters, ABB has played a prominent part in detecting leaks in the network.
Australia is the driest inhabited continent in the world. Treating and reusing water creates a “new” water source, says The World Resources Institute (WRI) and may hold the key to alleviating severe water stress. Aside from the water reuse there are other by products of recycling our wastewater.
Glenelg wastewater treatment plant in southwest Adelaide, Australia delivers 3.8 bllion liters of reused water for recreation and commercial purposes every year. In order to achieve that it uses the most reliable and accurate measurement instruments to ensure that water is safe to be discharged back into the environment. ABB’s AWT440 transmitter and ADS430 dissolved oxygen are successfully working at the plant reducing air consumption and increasing plant efficiency.
Singapore's water comes from four sources that include reservoir water, imported water from Malaysia, ultra-clean, high-grade reclaimed water (branded NEWater in Singapore) and desalinated water. ABB have been commissioned to design, engineer, manufacture, install and commissions the complete plant electrification, instrumentation and water analyzers. As a dual-mode facility, the Marina East Desalination Plant will be able to treat either fresh or sea water, depending on wet or dry weather conditions, thus reducing plant energy usage when freshwater is abundant.
Digital measurement technology is helping water companies around the world to sustain the growth in demand and an increasingly unpredictable supply of water. Finding a route to satisfy the growing demand for water is arguably only achievable through maximising efficiency of our water treatment. Happily, a by-product of doing so is also minimizing the environmental impact of water treatment and distribution. Advanced digital instruments and analysis is helping water utilities to meet the needs and expectations of a growing population.
