ISO 9001:2015 & QCI Approved
Sewage Treatment Plant (STP) Manufacturer in India
Trity Environ Solutions is a leading sewage treatment plant (STP) manufacturer in India, designing and installing systems that treat domestic and institutional wastewater reliably, from MBBR and SBR to MBR and packaged units. With over 14 years of experience and 2,300+ installations across India, every plant is engineered around your actual flow pattern, backed by pan India installation and service support.
SPCB / CPCB Norm Compliant
Heavy Fabrication
One Technology Doesn't Fit Every Building
At Trity Environ Solutions, we manufacture sewage treatment plants using multiple proven technologies rather than pushing a single default system onto every project. A hotel with sharp flow peaks, a residential society with steady daily generation, and a remote site without centralized sewer access all need genuinely different solutions, whether that's MBBR technology for compact retrofits, SBR based treatment for batch flexibility, or a packaged STP unit for fast deployment.
As an established STP manufacturer in India, we study your actual flow, space, and reuse requirements before recommending a technology, not the other way around.

KEY BENEFITS
Key Benefits of Sewage Treatment Plant (STP) Manufacturer in India
Engineered for full *CPCB compliance, low lifecycle operating cost, and reliable sewage treatment* performance across building types.
Full PCB Compliance
Engineered for full CPCB and State Pollution Control Board compliance, treating domestic and institutional sewage to meet discharge and reuse standards consistently across every project.
Low Power & Operational Cost
Reduces long term operating costs through energy optimized aeration, efficient blower selection, and low maintenance equipment built for continuous, unattended plant operation.
Technology Matched to Your Building
Custom designed around your actual flow pattern and site constraints rather than a fixed template, ensuring the right technology for your building type.
Compact & Space Efficient
Compact, space efficient plant layouts reduce footprint requirements without compromising treatment capacity, ideal for sites with genuinely limited installation area.
Automated PLC / SCADA Control
Automated PLC and SCADA control systems provide real time monitoring and reduce manual operator dependency for consistent plant performance around the clock.
Supports Water Reuse
Supports safe water reuse for flushing, gardening, and cooling applications, reducing freshwater dependency and lowering overall water procurement costs for the facility.
Why Sewage Treatment Isn't Optional Anymore
India generates over 72,000 million litres of domestic sewage daily, yet treatment capacity covers only a fraction of that volume, and the National Green Tribunal has grown increasingly active in penalising non-compliant buildings, from individual villas to large apartment complexes. A properly designed sewage treatment plant isn't just a legal requirement anymore, it protects groundwater, prevents disease transmission, and increasingly determines whether a project clears environmental approvals at all.
Choosing a Technology Should Follow Your Site, Not a Sales Pitch
Every STP technology, from MBBR sewage treatment to MBR filtration systems to extended aeration plants, has genuine trade-offs in cost, footprint, and effluent quality, and no single technology is correct for every project. Trity Environ Solutions backs every recommendation with an honest technical assessment and an Annual Maintenance Contract, so the plant you get is the one your site actually needs.

SYSTEM CONFIGURATIONS
Types of Sewage Treatment Plant (STP) Manufacturer in India Configurations
Technology-specific *STP configurations engineered around your flow pattern, space, and water reuse* requirements.
MBBR Sewage Treatment Plant
Our MBBR sewage treatment plant uses floating HDPE bio-carrier media in a compact, retrofit friendly aeration tank, well suited for residential, hotel, and hospital sewage with variable flow.
SBR Sewage Treatment Plant
Our SBR sewage treatment plant uses a time-sequenced fill, react, settle, and decant batch process that eliminates the need for a separate clarifier while achieving nitrogen removal.
FAB Sewage Treatment Plant
Our FAB sewage treatment plant uses high surface area floating media and fine bubble aeration for a very compact, low power, low odour treatment footprint.
Extended Aeration Sewage Treatment Plant
Our extended aeration STP is a proven, economical biological process with a longer retention time, well suited for smaller projects prioritizing lower capital cost.
MBR Sewage Treatment Plant
Our MBR sewage treatment plant combines biological treatment with submerged membrane filtration for superior, reuse-grade effluent quality where water reuse is a genuine priority.
SAFF Sewage Treatment Plant
Our SAFF sewage treatment plant is a hybrid fixed film and suspended growth process offering high shock load tolerance and low odour operation for medium strength sewage.
Packaged / Containerized STP
Our packaged and containerized STP is a factory-built, pre-tested system that installs within days, ideal for remote sites, tight timelines, or facilities without centralized sewer access.
STEP-BY-STEP WORKFLOW
How the Sewage Treatment Plant (STP) Manufacturer in India Process Works
A sequential, multi-stage *sewage treatment process engineered for consistent, CPCB compliant* discharge or reuse.
01
Screening & Equalization
Raw sewage passes through screening to remove solids, then flows into an equalization tank to balance flow before biological treatment begins.
02
Biological Treatment
Depending on the technology selected, MBBR, SBR, FAB, extended aeration, or MBR processes break down organic pollutants and reduce BOD and COD levels.
03
Clarification / Separation
Treated water is separated from biological solids through gravity settling or membrane filtration, depending on the plant configuration used.
04
Disinfection & Discharge
Clarified water is disinfected before discharge or directed to tertiary filtration for reuse in flushing, gardening, or cooling applications.
COMMON INQUIRIES
Frequently Asked Questions
Q1. What is a sewage treatment plant (STP)?
A sewage treatment plant treats domestic and institutional wastewater to remove organic matter, pathogens, and suspended solids before discharge or reuse for applications like flushing and gardening.
Q2. Which STP technology is best for my building?
The right technology depends on your flow pattern, available space, and reuse goals, with options ranging from compact MBBR and SAFF to premium MBR or economical extended aeration.
Q3. Is an STP legally mandatory for residential buildings?
Most states require STPs for residential societies, hotels, and commercial buildings above a certain size, with the National Green Tribunal actively enforcing compliance across India.
Q4. How much space does an STP require?
Space requirements depend on daily flow and the technology selected, with compact options like MBBR, FAB, and SAFF generally requiring less area than extended aeration.
Q5. Can treated sewage water be reused?
Yes, with appropriate tertiary treatment and disinfection, STP treated water can typically be reused for flushing, gardening, and cooling tower applications within the same facility.
Q6. How long does it take to install an STP?
Civil construction based plants typically take several weeks to months, while packaged or containerized units can be installed within 3 to 5 days of reaching site.
Q7. What is the difference between an STP and an ETP?
An STP treats domestic sewage, which is generally consistent in composition, while an ETP treats industrial effluent, which varies significantly depending on the manufacturing process involved.
Q8. How often does an STP need maintenance?
Regular maintenance, including blower checks, media inspection, and sludge management, is typically required, with an Annual Maintenance Contract ensuring consistent long-term performance.
Q9. Can an existing, underperforming STP be upgraded?
Yes, many existing STPs can be revamped by adding technology such as MBBR or FAB media, or by resizing aeration and equalization capacity to match current flow.
Q10. What discharge standards must treated sewage meet?
Treated sewage must meet CPCB and State Pollution Control Board norms for parameters such as BOD, COD, and TSS, which vary slightly depending on the discharge or reuse application. ---
