Today, all urban water infrastructures and utilities share strikingly similar issues, important among them being ageing water networks, escalating demand and rising customers’ expectations. In India, SUEZ supports the customers with a unified approach to these challenges and a plan for the future.
In India, SUEZ has introduced the Helium Leak Detection technique in India that detects invisible leaks in the water network. This technique is a major milestone in two significant ways – 40-50% of water is usually lost in the network due to invisible leaks, and in the absence of any technology to detect it, utilities are generally not aware of the cause of this consecutive colossal loss. Secondly, it is particularly helpful for Indian cities because it is a very compact technique and thus causes zero residents’ disruption – all work could be carried out on during the busy traffic hours. The detection can also be undertaken in the crowded narrow streets of slum and urban villages.
SUEZ's solution prioritizes water network renewal and rehabilitation to optimize medium and long-term investment and a preventative maintenance plan which prolong the life of the utility, network and preserve assets. We have expertise in optimizing water supply network in India including laying out new networks. Our GIS-based Water Information System assists our clients in strategic planning, resource mobilization, and utilization, streamlining management of day-to-day operations for the utilities.
Leveraging our expertise to make water services better for Bengaluru
In Bangaluru, SUEZ successfully improved a Water Distribution System spread on an area of 26.5 km2 covering 725 kilometers of the distribution network and 86,349 connections in the central region of the city. It also reduced Unaccounted for Water (UFW) level significantly towards the completion of the project. It was done through survey and mapping of assets, design, and establishment of District Metered Areas (DMAs) for measurement and monitoring of UFW levels, reduction of losses through systematically planned actions of rehabilitation of old corroded and clogged network, service connections, defunct consumer meters, identification and repair of visible and invisible leaks.
Direct from the tap: How SUEZ implemented 24/7 water supply in Delhi
24/7 water supply could be a significant step towards improving public health and ensuring a better quality of life. Hence, in India, we are working in different cities, preparing the network to deliver water continuously. This is a gradual process, and once done, we will be able to ensure better access to water for all.
When water gets supplied 24 hours a day, the pipes remain full, and the water stays clean. Under intermittent service, when pumping stops and the pressure in the pipes drops, the sewage flowing along the water network may potentially enter the pipe through the leakages and mix during the supply hours, thus contaminating the potable water. A continuous water supply does not allow the contaminants to enter, thereby, keeping the water safe for the consumers.
In 2012, the Delhi Jal Board entrusted SUEZ with a public-private partnership to improve water distribution service in the Malviya Nagar district. The goal of the contract is to implement SUEZ’s expertise to ensure continuous supply of water to the district’s 400,000 inhabitants. As part of our sustained efforts towards improving water supply in our project area, we identified Navjeevan Vihar to implement a pilot project to initiate a 24/7 water supply program.
