Sewage & Effluent Treatment Plant in Chennai
Tigreen designs, pre-builds, and installs compact, modular STP and ETP wastewater treatment plants for apartments, factories, tech parks, and hotels in Chennai. TNPCB compliant. Fits in 1 car parking space.
Meeting TNPCB Norms in Chennai with Pre-Built Systems
Wastewater discharge norms defined by the Tamil Nadu Pollution Control Board (TNPCB) require robust, reliable sewage treatment plants (STP) and effluent treatment plants (ETP). For facilities in Chennai, conventional civil construction takes months, disrupts site logistics, and requires massive space footprints.
Tigreen offers a pre-engineered, factory-tested alternative. Our modular packaged units are manufactured at our state-of-the-art facility and shipped directly to your location in Chennai as a complete plug-and-play system. No deep excavation, no permanent concrete pools, and complete commissioning in just 1 week.
Through our proprietary radical microbubble flotation technology, we guarantee up to 85% water recovery. The tertiary treated water is perfectly safe and compliant for reuse in landscape irrigation, flushing, and cooling towers, significantly cutting your fresh water tanker reliance.

Guaranteed Output Parameters vs. TNPCB Limits
Tigreen's advanced flotation and multi-barrier filtration system delivers treated water that consistently performs far better than standard local board thresholds.
| Wastewater Parameter | Unit | TNPCB Max Limit | Tigreen Guaranteed Output |
|---|---|---|---|
| pH Value | pH | 5.5 - 9.0 | 7.0 - 7.6 |
| Biological Oxygen Demand (BOD) | mg/L | < 10 | < 5 |
| Chemical Oxygen Demand (COD) | mg/L | < 50 | < 15 |
| Total Suspended Solids (TSS) | mg/L | < 10 | < 2 |
| Turbidity | NTU | < 2 | < 0.8 |
| Fecal Coliform | MPN/100ml | Nil | Undetectable |

Frequently Asked Questions — Chennai
Is Tigreen's STP compliant with TNPCB standards in Chennai?
Yes. Our modular systems meet all Tamil Nadu Pollution Control Board (TNPCB) discharge parameters, including stringent pH, TSS, BOD (< 10 mg/L), and COD (< 50 mg/L) targets, allowing seamless Consent to Operate (CTO) renewals.
What is the typical operating cost (OPEX) for a Tigreen STP in Chennai?
Operating costs average between 12 to 16 INR per kiloliter (KL) of treated water. Because the system is automated via cloud IoT telemetry, there is no need for a dedicated, full-time local operator, reducing personnel OPEX by up to 60%.
Does installation of a packaged STP require deep civil excavations?
No. Our packaged sewage systems are built on structural steel skids. They sit directly on a flat, level concrete foundation slab above ground, avoiding the high cost and structural risk of digging deep concrete collection pits.
