Easing water shortages in India’s Koppal district with digital water management solutions


In a unique 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 optimize 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 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 AbilityTM Symphony® Plus SCADA is designed to maximize reliability and availability of water plants and networks through integrated information management, integration of equipment, and process optimization based on the entire water network data for safer and enhanced operations.


The SCADA solutions help monitor and analyze 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 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. This makes AquaMaster 4 a perfect choice for Advance Metering Infrastructure (AMI) projects.


G Srinivas Rao, Head of ABB Measurement & Analytics in India, said: “As India moves swiftly towards smart and sustainable villages, towns and cities, one of the key challenges is water management. 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. We are proud partners in this project in the state where ABB India is headquartered, and in the district which contributes so significantly to our agricultural output.”

Avacta Group, the developer of Affimer® biotherapeutics and reagents, announce that it has entered into a collaboration with Integumen to evaluate recently generated Affimer reagents that bind the SARS-COV-2 spike protein for the detection of the coronavirus in waste water, to provide a real-time alert system to warn of localised COVID-19 outbreaks.


Hydrosense Pro, from Hydrosense, is a safe, customisable mobile-based reader and storage system which reads Hydrosense Legionella tests accurately and allows water management companies and their clients to store and share test results securely and remotely.


The app and accompanying portal are currently being used in water management and FM to facilitate crucial Legionella testing remotely, during yet another lockdown.


With further closures, water management professionals are finding it harder and harder to gain site access, and their employers are increasingly concerned for their safety when they are able to take samples in person.


With Hydrosense, easy, on-site Legionella testing kits can be distributed to clients where site access has been limited and the result data can be accessed by engineers from anywhere in the world, as long as they have access to a tablet or laptop and an internet connection.


With the remote data that is provided, engineers can monitor water systems and plan remedial work from home, or a socially distanced office, and only have to attend sites to carry out necessary work.


Alongside the Hydrosense Pro app and portal, Hydrosense provides an efficient and clever way to provide peace of mind to clients while keeping in-person interactions to a minimum.


The simplicity of the Hydrosense test means that anyone can carry out testing. Training clients on how to run the Hydrosense Legionella pneumophila serogroup 1 test is easy with Hydrosense’s demonstration videos and the comprehensive instructions included with each kit, which again can be provided remotely.

Over 60 percent of COVID-19 positive patients had gastrointestinal symptoms, such as diarrhoea, nausea and vomiting, and the SARS-COV-2 virus was found in their faecal samples. Sampling waste water from households may therefore provide an early warning system for localised outbreaks in communities.


Avacta’s CEO Alastair Smith


Recently, Avacta announced that it had generated a number of highly specific Affimer reagents that detect the SARS- COV-2 virus spike protein for use in diagnostic tests and in neutralising therapies.


The collaboration with Integumen aims to evaluate some of these Affimer reagents in next-generation sensors, based on the real-time bacteria detection and alert system1 developed by Rinocloud Ltd, a subsidiary of Integumen, with the aim of integrating these sensors into Modern Water plc’s Microtox water contamination system to detect the coronavirus. The Microtox system, which can detect the presence of contaminating bacteria, virus and toxins, is distributed by Modern Water and has a global footprint of over 3,000 installations. The proposed Affimer sensors would be consumable items to be replaced on a roughly monthly basis.


Once initial testing of the Affimer reagents is completed validation of the sensors will be carried out using SARS- COV-2 virus samples in a containment level 3 laboratory at the University of Aberdeen. Upon successful completion of this evaluation, Integumen and Avacta will enter into a supply agreement to allow Integumen to manufacture and commercialise the waste water detection sensors globally by retrofitting into Microtox systems.


Dr. Alastair Smith, Chief Executive of Avacta Group commented: “I am very pleased to be entering into this collaboration with Integumen, which holds substantial commercial potential for an Affimer-based consumable SARS-COV-2 detector unit to retrofit into the globally-installed base of Microtox systems. Affimer reagents are ideal for applications such as this, not only because of their sensitivity and specificity, but also because of their robustness, which is essential when being deployed in real-world situations, such as real-time waste water analysis.


With the spread of COVID-19 we are proud to work with partners like Integumen to provide our Affimer reagents for development on a range of platforms to combat the pandemic. This collaboration has the potential to deliver a product that will play a crucial role in the early detection of COVID-19 hotspots around the world.”


Gerard Brandon, CEO of Integumen and Chairman of Modern Water plc, commented: “We are delighted to be collaborating with Avacta, adding their highly specific and robust Affimer reagents to our real-time alert arsenal of pathogen capture devices for the COVID-19 virus in sewage. The global pandemic has highlighted waste water as a potential early warning hotspot detection opportunity and the inclusion of Affimer reagents adds an established method of capturing the virus to a widely used pathogen alert system.”
