What We Do
Biogas Plants: We build solid-waste-to-energy units that turn food and organic waste into clean fuel and compost.
Sewage Treatment Plants (STP): For societies, hospitals, hotels, and industrial zones—odor-free and high-efficiency systems that treat and reuse wastewater.
Effluent Treatment Plants (ETP): Customized systems for industrial wastewater—capable of handling pharmaceutical, food, brewery, washing, and ZLD processes
We offer comprehensive purification services—transforming natural water from rivers, wells, or rain into high-grade water via technologies like RO, UV, ion‑exchange, ozonation, and electro‑coagulation. Our systems enable water recycling for toilets, cooling towers, boiler feed, gardening, and more.
From feasibility studies and DPRs to topographical surveys and CAD/CAM design, our skilled team delivers turnkey solutions tailored to your specific waste profiles and plant needs. We also support regulatory compliance, project planning, and cost-effective strategy implementation.
- Full installation and commissioning services guarantee seamless plant setup.
- Robust Operation & Maintenance (O&M) packages include round‑the‑clock technical assistance, regular water-quality analysis, and field support by trained technicians, ensuring your system remains efficient and compliant
Our Core Offerings
