Water Treatment Excellence

Every drop of wastewater carries both risk and opportunity.

Poorly treated effluents pollute rivers, damage ecosystems, and threaten human health. Properly treated, they become a valuable resource for reuse, energy recovery, and sustainable growth.

Enviro delivers turnkey sewage and industrial wastewater treatment solutions including design and engineering through to commissioning and long-term operation. With over 400 references across India, our projects not only meet evolving discharge standards but set national benchmarks in reuse, recycling, and decarbonization.

Proven Industry Leadership
Decades of leadership in sewage and effluent treatment.
Lifecycle Excellence
End-to-end delivery covering design, engineering, construction, commissioning, and long-term O&M.
Sustainable Approach
Reduced energy use, sludge minimization, and resource recovery.

Our Treatment Process

Our wastewater treatment plants combine proven engineering with advanced innovation.
Preliminary Treatment
Preliminary Treatment
1

Incoming wastewater undergoes screening, grit removal, and oil and grease separation, followed by flow equalization and pH control to stabilize influent conditions and protect downstream treatment processes.

Primary Treatment
Primary Treatment
2

Primary clarification combines sedimentation with optimized chemical coagulation and flocculation to achieve reliable suspended solids removal and reduce the organic load entering biological treatment.

Secondary (Biological) Treatment
Secondary (Biological) Treatment
3

A range of proven biological treatment technologies are applied based on wastewater characteristics and project requirements. Suspended-growth systems such as CASP, SBR, MBR and oxidation ditches are complemented by attached-growth processes including MBBR, IFAS and trickling filters.
