Driving India's Water Transformation

WOG's Vision for Reuse, Decentralization, and Circularity

- 

WOG Technologies is a world leader in providing delegated management of water, wastewater services and renewable energy generation for industrial and municipal client. It designs the technological solutions and builds the facilities required for these services. Here, we are in an exclusive email conversation with Mr Sunil Rajan, CEO, WOG Technologies.

Please let us know about WOG's large-scale wastewater reuse projects reshaping industrial and municipal water management.

WOG's large-scale wastewater treatment and reuse projects have become critical benchmarks in regions experiencing severe water scarcity across India, Southeast Asia, and the Middle East. As freshwater sources shrink and regulatory frameworks tighten, industries and municipalities are rapidly shifting from a "treat-and-discharge" mindset to a "treat-reuse-recover" approach, and WOG has been at the forefront of this transition.

Across more than 1,200+ MLD of cumulative treatment capacity, WOG's advanced membrane bioreactor (MBR), MBBR, desalination, and ZLD systems are enabling cities and industries to reuse 60–90 per cent of their treated water. This has reduced freshwater dependence by 800+ million litres annually and helped industries meet stringent compliance norms while maintaining uninterrupted operations.

In highly water-stressed belts, such as Rajasthan, Tamil Nadu, Greater Jakarta, and parts of the Gulf, WOG's decentralized and industrial cluster solutions have transformed how water is managed. Industries that once relied on borewells or tanker water now operate using fully recycled process water. Phuket Project of WOG is one such example. Municipal bodies are now repurposing treated sewage water for landscaping, cooling towers, agriculture, and industrial supply networks.
