responsAbility Invests up to USD 25 Million in Roserve Enviro to Expand Water Treatment in India

India Zurich / Mumbai, 23 January 2026 – responsAbility will invest up to USD 25 million in Roserve Enviro, a Mumbai-based provider of energy-efficient wastewater treatment solutions for industrial clients across India. The transaction is part of responsAbility’s climate investment strategy for Asia, which targets scalable low-carbon technologies with measurable CO₂ reduction potential.

Roserve Enviro designs, builds and operates decentralized wastewater recycling and desalination systems for large industrial clients across India. Through a build‑own‑operate‑transfer (BOOT) model, the company enables clients to meet environmental compliance standards without upfront capital expenditure, while supporting more efficient and circular water use.

Its customers include leading Indian manufacturers across sectors such as Automotive, Chemicals, Pharmaceuticals, Food & Beverages. The company applies advanced technologies such as Reverse Osmosis (RO), Zero Liquid Discharge (ZLD) and Effluent Treatment Plants (ETP) and serves customers in sectors including pharmaceuticals, textiles, food and beverages and automotive.

Climate impact through industrial water reuse and decentralized infrastructure

The investment will support Roserve Enviro’s expansion into larger-scale BOOT projects and accelerate the deployment of decentralized water infrastructure across India’s industrial base. By enabling reuse of treated wastewater and reducing freshwater withdrawals, Roserve Enviro contributes to lower indirect CO₂ emissions from energy-intensive water supply and treatment processes.

The investment aligns with responsAbility’s climate investment strategy for Asia, which focuses on scalable solutions in renewable energy, energy efficiency, e-mobility and circular economy. The strategy targets total avoided emissions of approximately 16 million tons of CO₂ over the lifetime of its investments¹, backed by a rigorous climate impact assessment and monitoring framework.
