Concord Enviro Systems Limited

What Concord Enviro Systems Limited does

Concord Enviro Systems Limited is an India-based, publicly listed (NSE: CEWATER) integrated provider of industrial wastewater reuse and Zero Liquid Discharge (ZLD) solutions, founded in 1992 and headquartered in Mumbai. The company designs, manufactures, supplies, installs, and commissions water and wastewater treatment systems combining physio-chemical, biological, membrane separation, thermal, and non-thermal evaporation processes. Its proprietary technology stack includes the patented Plate & Tube membrane separation technology with recovery rates of 70-95%, the Membrane Brine Concentrator (MBC) that cuts fuel use by approximately 50%, and Green ZLD modular systems. The company serves enterprise and government customers across at least 17 industry verticals including pharmaceuticals, textiles, steel, chemicals, oil & gas, distillery, food & beverage, automobiles, electronics, mining, and seawater desalination for Indian defence forces.

The business operates through multiple channels including wholly-owned subsidiary Rochem Separation Systems (India) for end-to-end EPC project delivery, Roserve Enviro for zero-capex pay-per-use plant rentals, and Concord Enviro FZE in UAE for manufacturing and export operations. Revenue is generated primarily through one-time EPC project contracts (typical execution 12-28 weeks), recurring Operations & Maintenance services under multi-year AMCs, recurring pay-per-use rental subscriptions, and consumables/spares aftermarket sales. With installations across 5 continents recycling over 70 million litres of wastewater daily and an FY26 order book of Rs 828 crore, the company leverages 30+ years of operational history, ISO certifications, and government/defence relationships as core competitive assets. Recent strategic moves include a 2024 IPO, an April 2026 minority investment in US-based atmospheric water technology firm WaHa Inc., and a Rs 16 crore ZLD order from a domestic steel manufacturer in June 2026.
