PROCESS AUTOMATION
A DIGITAL SOLUTION TO SHORTAGES I
ABB’s digital water management solutions are helping India’s Koppel district to ease water shortages and ensure the supply of clean water
n a project led by L&T Construction Water & Effluent Treatment IC for the Government of Kartanaka, ABB’s end-to-end solutions will
help the local water authority to track, measure and optimise water use in this drought-stricken region of southwest India, as well as pump and distribute clean treated river water to village homes. The solution includes 635 digital flowmeters and technologies to improve control at pumping stations and reservoirs. With a population of around one million
people, the Koppal district is regularly challenged by water shortages. Until now, responses have relied on tradition, but thanks to digital technologies, the Kushtagi and Yelburga villages will benefit from ABB’s digital water management solutions as part of a multi-village clean drinking water scheme. Koppal needed solutions that could
effectively monitor water flow and manage leaks to reduce non-revenue water and achieve overall productivity improvement in a widely dispersed water distribution network set-up. L&T Construction Water & Effluent Treatment IC, the lead contractor for the project, chose ABB Ability Symphony Plus SCADA and ABB’s AquaMaster 4 flowmeters for the project. ABB’s engagement spans the
end-to-end automation and instrumentation of the project, from the pumping station at the river to the treatment of clean drinking water. The route comprises 620 overhead tanks and 16

reservoirs. The project involves putting in place a network of RTUs (remote terminal units) for remote locations and pumping stations and ABB Ability Symphony Plus SCADA to supervise and control the operation. The SCADA solutions help monitor and
analyse daily flow consumption patterns thereby identifying possible leaks and sending the information in real-time to the central control room. This helps to avert water loss because it means that leaks are identified and can be repaired swiftly. The AquaMaster 4 electromagnetic
flowmeters, running on battery power, will offer reliability even in low flow conditions, in areas where most mechanical flowmeters would fail. They offer measurement accuracy down to flow velocities lower than 0.1m/s. As the vast majority of leaks are small but continuous, the ability of AquaMaster to detect small variations in flow is crucial in combating the water shortage challenge. The AquaMaster 4 (pictured) is easy to install and use. Its Velox Mobile App interface saves time and
resources by eliminating the requirement for special cables, tools or the input of a trained engineer to set up the meter or read data on it. The device is largely self-sufficient in operation, with automatic self-health check and auto calibration features. The Velox App uses near-field communication (NFC), protected by strong encryption to avoid eavesdropping or tampering. With inbuilt tamper-proof datalogging, self-
diagnostics, and a smart integrated GPRS communication module, AquaMaster 4 facilitates automated meter reading (AMR) and links to an automatic billing system, providing transparency in consumption data, with user-specific tags and access control. GIS (geographical information systems) enable preventive maintenance and permit easy navigation to the site of a potential leak, thanks to Google Maps GPS assistance. The meters can be verified by the ABB Ability Verification for measurement devices solution, which extends the lifecycle of the product, validates accuracy, and provides the customer with a health-check report in accordance with the ISO9001 standard. . G Srinivas Rao, Head of ABB Measurement &
Analytics in India, said: “
...This project shows how ABB’s digital water management solutions can be deployed not only in cities but also to provide clean, drinking water in the villages that are crucial to our agrarian economy...”
