Trity Environ Solutions is a trusted sewage treatment plant manufacturer in Bihar, building MBBR, MBR, SBR, and packaged plants for housing societies, hospitals, hotels, malls, and campuses in Patna, Gaya, Muzaffarpur, Bhagalpur, and Begusarai. With one of the largest treatment gaps on the Tribunal's record, it designs plants that hold treated water inside limits and make it reusable, with pan India installation support behind every project. Trity Environ Solutions designs, manufactures, and commissions each plant in-house, from design to handover.
Bihar's sewage position is documented in two Tribunal orders. In May 2023 the National Green Tribunal assessed Rs 4,000 crore as compensation and cited a gap of 2,193 MLD between liquid waste generation and treatment, directing the state to prefer low cost options such as oxidation ponds and modular treatment plants over high cost plants in small towns and villages. In October 2024 it said there was no progress at the ground level, cited a gap of 1,102 MLD, recorded that Patna discharged 116 MLD of sewage without treatment, and named Gaya, Darbhanga, Purnia, Sasaram, Katihar, and Buxar as lacking proper sewage management.
A January 2025 review reported that sewage plants under the Namami Gange programme were under construction at Patna, Barh, Sonpur, and Sultanganj, and that total and faecal coliform in the Ganga exceeded standards because of untreated sewage. Those are the latest figures we could verify, so confirm current requirements with the Bihar State Pollution Control Board (BSPCB) and the local authority. For a housing project, hospital, hotel, or commercial building, treating on site is often the only reliable treatment. Trity Environ Solutions builds sewage treatment plants for Bihar's cities, and effluent treatment plants where a campus also generates process wastewater, designed against your real load and consent conditions.

Modular layouts for basements, podiums, and small plots in Patna where land is limited.
Factory built plants for smaller towns, in line with the low cost, modular direction the Tribunal has given.
Polished water for flushing, gardens, and cooling, which cuts fresh water demand and tanker use.
Stand alone plants that treat on site for projects with no connection to a public plant.
Installation, operator training, and AMC response across Bihar's cities, backed by Trity's engineering team.
With plants at Patna, Barh, Sonpur, and Sultanganj reported as under construction in early 2025, a project cannot assume a public connection. Sampling points, a flow meter, and a dated log of treated water quality give you evidence at inspection. A grey water treatment plant can separate lighter wastewater so more of it is reused.
Sewage plants drift when blowers, diffusers, and sludge handling are left unattended. Trity Environ Solutions supports every Bihar installation with operator training, performance checks, and an Annual Maintenance Contract, so treated water stays within limits through peak occupancy. Talk to our team about AMC coverage for your facility.
City pages cover the main sewage markets in Bihar: Patna, Gaya, Muzaffarpur, Bhagalpur, Begusarai. For projects in neighbouring states, Trity Environ Solutions also serves clients as an STP and ETP plant manufacturer in Jharkhand, an STP and ETP plant manufacturer in West Bengal, and an STP and ETP plant manufacturer in Uttar Pradesh, so eastern India projects can be handled by one team.
This page covers domestic and commercial sewage only. For industrial effluent from distillery, sugar mill, paper, and food units, see the effluent treatment plant manufacturer in Bihar page. The combined overview of both services is on the STP and ETP plant manufacturer in Bihar page.
Our MBBR sewage treatment plant fits basement and podium layouts and holds treated quality across peak swings.
Our MBR sewage treatment plant delivers high quality, low odour treated water in very little space, suited to reuse for cooling and flushing.
Our SBR sewage treatment plant treats large and variable flows in timed batches within a single tank.
Our packaged containerized sewage treatment plant is a factory built, quick to commission option for smaller flows and sites without much civil work.
Our sewage treatment plant for hospitals is built for hospital wastewater, with disinfection before discharge or reuse.
Flow measurement and sampling establish your actual load, including flow pattern, occupancy, and peak load.
Technology and layout are fixed against BSPCB consent conditions, available footprint, and reuse targets.
Components are manufactured under ISO 9001:2015 quality controls, then installed and commissioned by Trity's site team.
The plant is tested against consent limits, operators are trained, and ongoing AMC support keeps performance consistent afterward.
The Bihar State Pollution Control Board (BSPCB) issues consent to establish and consent to operate, alongside CPCB guidelines and National Green Tribunal directions.
Large residential, commercial, and healthcare projects generally need an STP as part of building approval and BSPCB consent conditions. Thresholds vary by project size, so confirm yours with BSPCB and the local authority.
An MBR or MBBR plant is the usual choice where land is limited and low odour matters, while SBR suits larger and more variable flows. The right option depends on your flow and available footprint.
Yes. Treated water can be reused for flushing, gardens, and cooling when it meets the required quality, with only the surplus discharged. The reuse purpose decides the final polishing stage.
Prefabricated modular plants typically commission within 45 to 90 days, while civil-based plants for larger capacities take 3 to 6 months from design approval to handover.
Yes. We audit existing plants, retrofit capacity or technology, and take them under an annual maintenance contract.
Look for in-house manufacturing, experience with BSPCB consent requirements, a design based on your own wastewater analysis, and a clear maintenance offering after commissioning. Trity Environ Solutions builds its plants under ISO 9001:2015 quality controls and supports every installation with operator training and an annual maintenance contract.
Our engineering team can help design the right system for your capacity, industry, and compliance requirements.
