Innovations that transformed the water industry in India

Over the last 30 years of our operation in India, wherein we have built more than 750 plants for municipalities and industries, we have revolutionized the water treatment technologies and completely transformed the industry. Our technologies are helping clients to be able to supply 5 billion liters of drinking water daily to 44 million people in various metropolitan and tier-1 and tier 2 cities. Our Water Services is positively impacting over 15 million people in major cities
Our achievements
Following are some of the innovations – contractual, technological and process – through which we have successfully brought major breakthroughs that has revolutionized the industry.


  • Back in the 1980s, when water treatment facilities were considered basically civil construction activities, with not much attention given to the array of possible treatment lines combining the processes and technologies, SUEZ challenged the traditionally deployed contracts and emphasized the need for Design and Build model, thus introducing a major shift in the mindset and the way the business was conducted. Subsequently, SUEZ introduced the Design-Build and Operate (DBO) approach, yet another shift that enabled the customer significant optimization and operational efficiency, capable of providing attractive savings and returns on investment. Today SUEZ’s O&M sites are best known for the preventative maintenance prolonging the life-cycle of the assets, flawless operation, etc.
  • Technology wise, SUEZ introduced several breakthroughs that was then unheard of. For instance, as long back as in 1989, the Group introduced ozonation & biological nitrification technology at Okhla treatment plant in New Delhi in order to treat the high ammonia level that was found in the groundwater. Ozone, a powerful oxidising agent from the ozonation unit, enhanced the water quality & efficiently took care of the bacteria, viruses, amoeba & algae.
  • Similarly, the Rithala Wastewater treatment plant, built in 2002 by SUEZ, was the first of its kind in India designed to produce effluent quality (BOD < 10 mg/l, TSS< 15mg/l), much better than the applicable discharge standards (BOD < 20 mg/l, TSS< 30mg/l) at that time. The plant was the first energy self-sufficient sewage treatment plant in India.
  • In 2006, SUEZ introduced a Membrane Bio-Reactor (MBR) plant at Cubbon Park in Bangalore. The plant was installed to treat municipal sewage and produce effluent complying with California Title-22 standards for its Urban Reuse (horticulture, gardening, firewater, etc.) in the VIP Zones in and around Cubbon Park.
  • SUEZ has customized Helium Leak Detection (HLD) technique in India to detect invisible leakages in the network. This technique has proved quite relevant and useful for India as it could be used in a network with intermittent supply, low pressure and of non-metallic pipes. It has been further customized by making it compact so that the leak detection can be carried in narrow and busy streets of urban villages and slums. The technique is highly accurate and leaks are detected without digging or damaging the roads.
  • A digital platform called ROPES has been developed to monitor and follow up on real-time performance of the operation teams in various water services project across various cities from our headquarters in Gurgaon and to optimize operational cost.
  • Customer services at all water services projects across all cities was improved by linking all the data to a centralized digital platform called Real Times Operation Performance System (ROPeS). All the data like leaks, water flow, pressure drops, etc. are produced, reported and analysed at the Center in real time helping the operators to resolve the incidents quickly. Such system has enabled us to successfully optimise the management of flows in real time, monitor networks continuously and anticipate incidents in our project areas.


In a company that is largely in public services, technology and processes can’t alone drive the performance and success of the company. The organization believes the talents of the men and women working at SUEZ are key to the transformation of our activities. They are the primary contributors to the Resource Revolution and responsible for developing innovative and value-creating solutions for our customers. Thus our organization is committed to a human resources policy that values commitment, diversity and skills development.
