Va Tech WABAG: An Indian MNC Leading Global Water Treatment
Va Tech WABAG Ltd, headquartered in Chennai, has firmly established itself as an Indian multinational corporation in the water treatment industry. The company generates nearly 50% of its revenue from international business, showcasing its robust global footprint. Despite ongoing geopolitical tensions in West Asia, which accounts for about 30% of its top-line revenue, WABAG remains optimistic about growth in the region. The company boasts a strong order book exceeding Rs 16,000 crore, underscoring its financial stability and market confidence.
Expansion into Emerging Sectors: Data Centers and Beyond
In an interview, CMD Rajiv Mittal highlighted WABAG's strategic expansion into high-growth areas such as data centers. He explained that data centers are a key emerging segment due to their significant consumption of energy and water, particularly for cooling systems. Cooling towers require large volumes of treated water that must be efficiently recirculated. WABAG adds value by supplying, treating, and recycling water in a cost-effective manner, positioning itself to capitalize on the rapid growth of this sector.
Mittal also discussed opportunities in new sectors like hydrogen, solar, and semiconductors. These industries demand ultra-pure water, far beyond drinking water standards. WABAG is engaging through smaller, technology-driven projects and has established dedicated teams to focus on these areas. Among them, solar is scaling the fastest, while hydrogen remains in an early stage of development. The company anticipates significant growth in these sectors over the next three to five years.
Tamil Nadu's Tech-Driven Water Model: A Blueprint for Success
Chennai is emerging as India's desalination capital, and Mittal praised Tamil Nadu's water model as a leader in adopting technology-driven solutions. He compared Chennai to Singapore, noting that both are in rain-shadow regions with no reliable perennial water sources, relying heavily on seasonal rainfall. Singapore addressed this early by investing in desalination and recycled water (NEWater), reducing dependence on imports. Chennai has followed a similar path, shifting from dependence on sources like Krishna, Cauvery, and Veeranam—which involved interstate dependencies—to a "manufactured water" model.
This model uses desalination for potable water and recycled water for industrial demand. With new desalination capacity, nearly 70% of Chennai's water needs are expected to be met through such systems, marking a transition to a tech-led, self-sustaining approach that replaces earlier reliance on inconsistent tanker supply. Mittal credited successive state governments for their openness to technology and long-term investments in desalination projects, such as large-scale 400 MLD plants, which support water-intensive industries like semiconductors and data centers.
Replicating the Model and Progress on Clean Ganga
When asked if Tamil Nadu's water model can be replicated in other water-scarce states, Mittal noted that some states, like Gujarat, rely on river systems such as the Narmada and extensive pipeline networks. However, he argued that a tech-driven model based on desalination and reuse is more reliable and sustainable. Rivers can dry up, but seawater and wastewater are perennial sources, making these systems effectively drought-proof.
Regarding the Clean Ganga project, Mittal stated that it has progressed far better than earlier efforts, though there is still scope for improvement. The Ganga holds deep cultural and religious significance for Hindus and flows across multiple states. WABAG has been involved along the entire stretch, from Uttarakhand to West Bengal, and Mittal expressed satisfaction with visible improvements in water quality, highlighting the project's positive impact.
