WOG Technologies plans Rs 375-crore IPO to expand biogas portfolio

Delhi-based environmental engineering firm WOG Technologies has filed its Draft Red Herring Prospectus (DRHP) with the Securities and Exchange Board of India (SEBI), marking its entry into the capital markets. The proposed initial public offering (IPO) comprises a fresh issue of equity shares worth Rs 375 crore and an offer for sale (OFS) of up to 43.28 lakh shares by promoters and early investors.

The IPO will be managed by Unistone Capital as the Book Running Lead Manager, while Bigshare Services has been appointed as the registrar to the issue.

Founded in 2010, WOG Technologies has evolved into a technology-led infrastructure company focused on water treatment, wastewater management, oil-water separation, and biogas generation systems. Positioned at the intersection of industrial sustainability and environmental compliance, the company offers end-to-end turnkey solutions spanning design, engineering, procurement, construction, commissioning, and post-commissioning operations and maintenance (O&M).

The company primarily operates through two business models. Its Engineering, Procurement and Construction/Management (EPC/EPM) segment contributes over 95 per cent of revenues, while O&M services provide a recurring income stream accounting for 3–5 per cent of turnover.

WOG Technologies has established a global footprint with operations across India. It also claims to have presence in Southeast Asia, the Middle East and the Caribbean. As of November 30, 2025, as per reports, WOG had executed 179 projects across nine Indian states and 16 international markets, with 34 active projects and an order book of Rs 1,012.96 crore.

The competitive strength of WOG lies in its in-house EPC capabilities and proprietary process engineering, enabling customised solutions, tighter cost control and predictable margins. It has also invested in advanced treatment technologies such as membrane bioreactors, zero-liquid discharge systems and waste-to-energy solutions.

In October 2025, WOG filed a patent for a novel UASB system, underlining its strategic push towards R&D-led growth. Its client portfolio includes HPCL, Saudi Aramco Technologies and Hyundai Engineering, with a high proportion of repeat customers reflecting long-term execution strength.

The Global Energy & Environment Foundation (GEEF) felicitated WOG Technologies with ‘Smart Water Treatment Technologies Company of the Year’ award in September 2025.
