Underground FRP Sewage Treatment Plant

Underground FRP Sewage Treatment Plant

Soma Utilities offers Underground FRP Sewage Treatment Plants (STP)
designed for projects where surface space must be preserved and
aesthetics are important. These STPs are installed below ground level,
making them ideal for residential, commercial, and institutional projects
requiring efficient sewage treatment without visible structures.
Our FRP STPs are corrosion-resistant, lightweight, and long-lasting,
ensuring reliable performance, low maintenance, and compliance with
CPCB / SPCB norms.

Treatment Technology – Underground FRP STP

Underground FRP Sewage Treatment Plants (STPs) are designed using proven biological technologies such as:

  • MBBR (Moving Bed Biofilm Reactor)
  • SBR (Sequential Batch Reactor)

Technology selection is based on inlet sewage characteristics and reuse requirements. Systems are available in 10 KLD to 100 KLD capacity range, with modular and expandable design.


Key Features & Advantages

✔ Completely underground installation – no impact on landscape
✔ High-strength, corrosion-resistant FRP construction
✔ Compact design with minimal civil work
✔ Odour-free and silent operation
✔ Low power consumption & low sludge generation
✔ Easy operation & maintenance
✔ Long service life
✔ Automation ready – PLC & IoT (Optional)


Tertiary Treatment Plant (TTP) – For Water Reuse

We also provide Tertiary Treatment Plants (TTP) along with STP systems to achieve higher water quality for reuse.

TTP Includes:

  • Pressure Sand Filter (PSF)
  • Activated Carbon Filter (ACF)
  • UF / Ozonation / UV (as required)

This ensures treated water is suitable for gardening, landscaping, and other non-potable uses, helping reduce freshwater consumption.

Treated Water Quality

Designed to meet CPCB discharge and reuse standards.

Typical Output Parameters:

  • pH: 7.5 – 8.5
  • BOD < 10 mg/L
  • COD < 50 mg/L
  • TSS < 10 mg/L
  • Oil & Grease < 10 mg/L

Applications

  • Residential Societies & Villas
  • Commercial Buildings & Offices
  • Hotels, Resorts & Clubs
  • Hospitals & Institutions
  • Schools, Colleges & Campuses
