Core Business Operations and Market Footprint
The company operates as an end-to-end solutions provider, covering plant design, equipment manufacturing, installation, commissioning, and operations and maintenance services. Its proprietary C-Tech technology utilises the sequencing batch reactor (SBR) process for treating sewage and industrial effluents. As of 31 July 2026, the firm had successfully commissioned 728 wastewater treatment installations, facilitating the treatment of 17,511.11 million litres per day (MLD) of wastewater. The company states it holds over 80% market share in India’s SBR technology segment.
Beyond standard sewage treatment, the company maintains a robust wastewater recycling and reuse (WRR) portfolio. This includes ultrafiltration, closed-circuit reverse osmosis, and membrane bioreactor technologies, backed by an exclusive supply arrangement with DuPont. The WRR segment recorded an order book of INR 561.07 crore as of 31 August 2026. In solid waste treatment, the company deploys its proprietary OREX technology to separate biodegradable organic waste from inorganic materials. It operates two integrated facilities in Goa boasting a combined treatment capacity of 350 tonnes per day (TPD), supplemented by an additional handling capacity of 75 TPD.
Diversifying into waste-to-energy solutions, the company has expanded into compressed biogas (CBG). Through its subsidiary, Vasudha Waste Treatment Private Limited, it secured orders worth INR 501.70 crore for two municipal solid waste-based CBG plants located in Assam and Odisha, which include 10-year operations and maintenance contracts.
