GNN Tertiary Treatment Reverse Osmosis (TTRO) Â Plant, Ghaziabad, India
India’s Leading Water Recycling and Reuse Plant Strengthening Industrial Water Security in Ghaziabad
The 40 MLD Ghaziabad Tertiary Treatment Reverse Osmosis (TTRO)  facility is one of India’s most advanced water recycling and reuse plants, implemented under the Hybrid Annuity Model (HAM) for Ghaziabad Nagar Nigam. The project transforms municipal wastewater into high-quality reclaimed water, enabling large-scale industrial reuse and reducing pressure on groundwater resources across the Sahibabad Industrial Area.
Advanced Water Reclamation Plant Enabling Circular Water Use
Designed as part of a circular economy model, this water reclamation plant integrates a 56 MLD sewage treatment plant with a 40 MLD Tertiary Treatment Reverse Osmosis (TTRO) plant. Together, these systems convert treated wastewater into premium-grade non-potable water that meets industrial requirements, positioning Ghaziabad as a national reference point for municipal wastewater reuse.
Tertiary Treatment Reverse Osmosis (TTRO) Â Plant Delivering High-Quality Treated Wastewater Reuse
The Tertiary Treatment Reverse Osmosis (TTRO) Â plant employs a multi-stage purification system including Ultra-Filtration (UF) and Reverse Osmosis (RO), ensuring consistent water quality for industrial applications. The reclaimed water is distributed through a 12 sq. km smart water network equipped with digital metering systems, serving over 1,500 industries and reducing dependence on freshwater sources.
A Landmark Project by One of the Leading Water Recycling Companies Globally
Backed by India’s first municipal Green Bond, this project underscores WABAG’s leadership among leading water recycling companies globally. By enabling municipal wastewater reuse at scale, the facility improves regional water resilience and supports Ghaziabad’s sustainability and climate-responsible urban development goals.
Comprehensive Scope for a Future-Ready Water Recycling and Reuse Plant
The project scope includes:
- Design, Build, Finance, and Operation under HAM
- 40 MLD TTRO Plant
- 56 MLD STP (O&M)
- UGSR (50 lakh litres) and ESR (28 lakh litres)
- 12 sq. km industrial water pipeline network with smart metering
This complete lifecycle approach ensures long-term performance, financial sustainability, and reliability in treated wastewater reuse.
Advanced Treatment Process Ensuring High-Purity Reclaimed Water
The water reclamation plant incorporates:
- Ultra-Filtration (UF) for fine particle removal
- Reverse Osmosis (RO) for high-purity treated wastewater reuse
- Multi-barrier disinfection
- Smart Water Metering System for real-time monitoring
These technologies ensure consistent reclaimed water quality suitable for industrial operations with stringent process requirements.
Tertiary Treatment Reverse Osmosis (TTRO) Â Plant Delivering Sustainable Industrial Water Supply
As a flagship Tertiary Treatment Reverse Osmosis (TTRO) Â plant in India, the facility drastically reduces groundwater extraction by providing industries with a reliable recycled water supply. The plant prevents the withdrawal of approximately 14,000 million litres of groundwater annually, supporting long-term aquifer recovery and sustainable industrial growth.
Environmental and Economic Impact for Ghaziabad
- Supplies reclaimed water to 1,500+ industries
- Reduces pollution load on the Hindon River
- Enables municipal wastewater reuse at scale
- Backed by India’s first municipal Green Bond
- Achieved 778,000+ safe man-hours during implementation
The project demonstrates how treated wastewater reuse can drive urban resilience, reduce freshwater stress, and support industrial expansion without environmental compromise.
A Benchmark Among Leading Water Recycling Companies Globally
Through this Tertiary Treatment Reverse Osmosis (TTRO) plant, WABAG reinforces its position among leading water recycling companies globally. The project stands as a national model for integrating advanced Tertiary Treatment Reverse Osmosis (TTRO) technology, smart distribution, and sustainable municipal wastewater reuse.
