Sewage Treatment
Plants (STP)
Custom-designed sewage treatment systems for residential complexes, commercial buildings, hotels, hospitals and institutions requiring compliant wastewater management.
Compliant STP Systems for Residential, Commercial and Institutional Use
Vannsol designs and installs Sewage Treatment Plants for facilities that generate domestic wastewater from toilets, kitchens and bathrooms and need to treat it for safe discharge or reuse. All systems are designed to meet CPCB and State Pollution Control Board norms.
We evaluate your daily sewage generation, peak flow, available space, civil constraints and reuse requirements before recommending any treatment configuration. Treated water can be recycled for flushing, gardening and cooling tower makeup, significantly reducing freshwater dependency.

Why Vannsol
A compliant STP protects your facility from legal risk and enables water recycling.
We Design STP Systems That Meet Norms and Recover Water for Reuse.
Many facilities install STPs only for compliance and let treated water go to drain. Vannsol designs STP systems with tertiary polishing that produces reuse-quality treated water for toilet flushing, garden irrigation and cooling tower makeup, reducing your freshwater consumption significantly.
Space-Efficient Design
Underground, semi-underground or above-ground configurations to fit your available site space.
Low Odour Operation
Enclosed systems with proper ventilation and odour control for facilities with residents or patients nearby.

Frequently Asked Questions
Common questions about sewage treatment for buildings and institutions.
Yes. Most state building regulations, RERA requirements and municipal authority guidelines mandate STPs for residential complexes above a certain number of units and commercial buildings above a certain floor area. Requirements vary by state and local authority.
