Digital water management solutions for India’s Koppal district

December 12, 2020 11:55 am

With a population of around one million people, the Koppal district is regularly challenged by water shortages. Until now, responses have ranged from preserving ancient wells to following age-old water conservation practices, but thanks to digital technologies, the Kushtagi and Yelburga villages will soon 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, sanctioned by the Rural Water Supply & Sanitation Department, Koppal, Karnataka.

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. ABB Ability^TM Symphony® Plus SCADA is designed to maximise reliability and availability of water plants and networks through  integrated information management, integration of equipment, and process optimisation based on the entire water network data for safer and enhanced operations.

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.

ABB’s AquaMaster 4 elctromagnetic 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 where most meters struggle to even detect flow.  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 in the Koppal district.

The AquaMaster 4 is a first of its kind digital flowmeter that is easy to install and use. Its unique 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. ABB Velox App uses near-field communication (NFC), protected by strong encryption to avoid eavesdropping or tampering.

With inbuilt tamper-proof data logging, 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. This makes AquaMaster 4 a perfect choice for Advance Metering Infrastructure (AMI) projects.
