Complete Guide to CPCB Norms for Sewage Treatment Plants in India
Compliance with CPCB norms for STP plants is mandatory for residential, commercial, and industrial projects in India. The Central Pollution Control Board (CPCB) sets strict discharge standards to control water pollution and promote wastewater reuse.
3D Aqua helps clients design and install CPCB-approved STP plants that meet all regulatory requirements with long-term operational efficiency.

What Are CPCB Norms for STP Plant?
CPCB norms define treated sewage quality parameters that must be achieved before discharge or reuse. These standards apply to:
- Apartments & housing societies
- Hotels & resorts
- Hospitals & healthcare facilities
- IT parks & commercial buildings
- Industrial units
Failure to comply may lead to heavy penalties, closure notices, or legal action.

CPCB Treated Water Discharge Standards
As per latest CPCB guidelines, treated wastewater from STP plants must meet the following limits:
| Parameter | CPCB Limit |
| pH | 6.5 – 8.5 |
| BOD | ≤ 10 mg/L |
| COD | ≤ 50 mg/L |
| TSS | ≤ 20 mg/L |
| Oil & Grease | ≤ 5 mg/L |
| Fecal Coliform | ≤ 100 MPN/100 ml |
👉 These limits are mandatory for surface discharge and reuse applications.
