Sewage Treatment Plants (STP)

Sewage Treatment Plants (STP) – Smart, Sustainable Wastewater Management

A Sewage Treatment Plant (STP) is an engineered system designed to treat domestic and commercial wastewater (sewage) so it can be safely reused or discharged into the environment. It removes suspended solids, organic matter, nutrients, and pathogens , making the water compliant with environmental standards.

How it Works

• Preliminary Treatment – Removes large solids, grit, and oil.
• Primary Treatment – Allows suspended solids to settle through sedimentation.
• Secondary (Biological) Treatment – Uses aerobic or anaerobic bacteria to break down organic matter (BOD/COD reduction).
• Tertiary Treatment – Includes filtration, chlorination, UV or ozone disinfection for final polishing.
• Sludge Handling – Stabilization, dewatering, and safe disposal or reuse of sludge.

Applications

• Residential complexes, townships, and smart cities
• Hotels, hospitals, commercial buildings
• Educational and institutional campuses
• Industries with domestic sewage generation
• Infrastructure and municipal bodies

Advantages

• Reduces pollution load on natural water bodies
• Enables treated water reuse for gardening, flushing, cooling
• Complies with GPCB/CPCB discharge norms
• Helps in zero liquid discharge (ZLD) efforts
• Promotes water conservation and sustainability
