STP & ETP for Societies and Townships in India

Why Must Societies & Apartments Have STP/ETP?
- NGT & RERA Mandate: All group housing societies (typically 20+ flats) must have their own STP for sewage treatment—no direct sewerage allowed in most cities.
- Zero Pollution: Prevents untreated domestic waste from contaminating rivers and groundwater.
- Water Reuse: Treated water can be used for gardening, flushing, and road cleaning—saving lakhs per year in fresh water bills.
- Value & Compliance: No completion certificate (CC/OC), property registration, or sale allowed without a functional, tested STP in many states.
What Makes a Good Society STP/ETP?
- Ultra-compact, low-noise, and odorless (ideal for basements, parking, or green zone)
- Fully automatic or semi-automatic for easy society operation
- Robust design for variable loads (weekend/holiday/seasonal occupancy)
- Meets PCB norms for BOD, COD, TSS, pH, and coliform
- Smart metering, remote alerts, and maintenance reminders (optional)
