Creating new water resources

As the population grows and urbanization continues, the pressure on water resources has increased. We’re addressing this by developing innovative solutions, like the reuse of urban and industrial wastewater, desalination, etc.

Reducing the environmental footprint

Strong economic growth and rapid urbanization of cities have resulted in an exponential rise in urban water demand and wastewater generation. Untreated discharge of wastewater from the cities into surface water bodies has caused pollution of raw water sources, impacting the water availability for human consumption, and consequences on the environment, aquatic life-forms and ecology. Urban wastewater management has, therefore, become a key concern for the city authorities. It is time to take concrete action, to create a sustainable model of growth and development, in harmony with the environment and ecology.

SUEZ has over 70 years of global experience of partnering with the local authorities in creating a robust urban wastewater treatment and management infrastructure. With over 40 years of its operation in India, and understanding of local conditions and needs, the authorities trust SUEZ's expertise in tackling the challenges of increasing wastewater in India and transforming it to a new resource.

Transforming wastewater into use 

The first module of Cubbon Park Tertiary Treatment Plant of 1.5 MLD capacity in Bengaluru, designed and commissioned by SUEZ in 2006, was the first Indian Membrane Bioreactor Plant for a Public Utility Board. The plant was built to treat municipal sewage and produce effluent complying with California Title-22 standards, for reuse in and around the Park.
The treated water gets pumped from a reservoir to a sprinkler system, fitted at the 250-acre park, and the rest is used for watering other facilities near the area. Advanced and state-of-the-art MBR technology for this project was selected keeping in mind the high-profile location (Cubbon Park), allocation of very little space with strict restrictions on trees cutting, odourless and noiseless process to avoid adverse impact on the general environment of the park, aesthetics, and health and safety considerations of treated sewage reuse in public areas.

SUEZ implemented its ULTRAFOR® MBR technology, with submerged vacuum driven ultrafiltration membranes, sourced from SUEZ Water Technologies and Solutions. A SCADA system was installed to fully automated operation, monitoring, and control. Thanks to our in-house expertise in operation and maintenance and knowledge, the membranes' lifecycle was extended by 30%, over and above of what was guaranteed by the membrane manufacturer.


The capacity of Cubbon Park STP has been recently upgraded from 1.5 to 4 MLD due to high demand for recycled water from government buildings.

Reusing municipal wastewater for power generation

The 10 MLD Delhi Gate Nallah and SNH Nalla Wastewater Treatment Plant are built with SUEZ Densadeg® Clarifier and Biofor® Biofiltration technology on less than 2.5 acres swampy and waterlogged piece of land where no other contemporary technology would fit. In 2005, SUEZ commissioned these plants. Today, these two plants are the workhorses for 330 MW Pragati Power Station, continuously supplying over 20 MLD of high quality treated effluent as Cooling Towers Makeup Water and raw water to DM Water production unit for Steam Turbines. SUEZ operates and maintains the plants.

Solving the toughest water challenges for industries

Industries use a significant amount of water in day-to-day processes. With increasing enforcement and tightening of discharge regulations, they are seeking the most advanced technologies to use alternative water resources and move towards improved water management approach that can help them overcome water-related risks that would impact their operations and growth strategies. They are aiming at a paradigm shift in their water resource management and strengthen their resilience to water-related challenges and risks.  

Our mission is to enable our customers to meet increasing water demands, overcome scarcity challenges, enhance their environmental stewardship and comply with regulatory requirements.

How we helped Tata Chemicals Mithapur plant maintain production 

Unable to get fresh water, Tata Chemicals plant was faced with two scenarios - shutting down production or finding an alternative source for their water needs. Tata Chemicals turned to SUEZ for the solution. SUEZ evaluated the options and recommended a flexible Outsourced Water Services Agreement where SUEZ would provide fresh water from the only available water source – seawater.
The solution consists of a seawater reverse osmosis (SWRO) system for the production water needs and an additional brackish water reverse osmosis (BWRO) system for the demineralization plant. SUEZ’s outsourced water projects provide customers with little or no capital expenditure, reduced operating costs, and improved technical performance.

FMCG company saves chemical consumption and creates reuse opportunity

An FMCG company in the northern part of India, which manufactures chocolate powder and analgesics required a water treatment solution to reduce its raw water utilization by recycling its treated wastewater effluent and save regeneration of chemicals. The company also needed a wastewater recovery scheme, which could handle variations in feedwater quality such as TDS, TSS, and temperature. Working with the customer’s parameters, SUEZ proposed a conventional RO system for reject recovery. With the commissioning of this plant, the RO and EDR system reduced the chemical use by ten times and helped save the company US$200,000 per year.
