Our Services

Specialized environmental engineering solutions—from plant design to long-term maintenance—built for performance, compliance, and sustainability.

Design & Installation of New Treatment Plants

We specialize in turnkey design and installation of Sewage Treatment Plants (STP) and Effluent Treatment Plants (ETP) tailored to your site's capacity, inflow characteristics, and regulatory needs. Our team ensures optimized layouts, efficient space use, and long-term operability.

Upgradation of Existing Plants with Modern Technology

We upgrade aging or underperforming treatment plants using advanced technologies such as MBBR, SBR, and automation systems. Our retrofit solutions enhance process efficiency, energy savings, and compliance with the latest pollution control norms.

Operation & Maintenance (O&M) Services

Reliable plant performance depends on expert operation and consistent maintenance. Our O&M team ensures smooth daily functioning, timely servicing, troubleshooting, and reporting—minimizing downtime and maximizing efficiency.

Revamping & Repair of Non-Functional Plants

We restore defunct or inefficient treatment plants by identifying structural, mechanical, and process issues. Our team handles complete overhauls, reengineering, and upgrades to bring systems back to optimal performance levels.

Environmental Consultancy for STP & OWC

Our consultancy services help clients navigate complex environmental regulations. We assist with planning, documentation, and securing environmental clearances for treatment plants and Organic Waste Converters (OWC), ensuring full legal compliance.

Compact & Containerized Treatment Solutions

Ideal for space-constrained or remote locations, our prefabricated, plug-and-play units offer efficient wastewater treatment without heavy civil work. These modular systems are easy to install, relocate, and maintain.
