Modular & Custom Sewage Treatment Plants (STP)

Decentralized Wastewater Infrastructure for Sustainable Development

With the Ministry of Environment, Forest and Climate Change (MoEF&CC) and National Green Tribunal (NGT) enforcing stringent discharge and mandatory nutrient removal, domestic wastewater management is a critical pillar of compliance for commercial complexes, industrial townships, residential projects, and municipal bodies.

We deliver both Pre-Engineered Modular STPs for rapid deployment and Bespoke Custom Concrete STPs for large-scale infrastructure. Our systems focus on maximizing water reuse for flushing, landscaping, and cooling tower makeup, effectively lowering your fresh water footprint and ensuring absolute alignment with SPCB norms.

Our Treatment Delivery Models

We bridge the gap between space constraints and high-capacity demands through two distinct delivery configurations:

1. Plug-and-Play Modular STPs (Packaged Systems)

Designed for rapid installation, minimal footprint, and ease of relocation. These containerized or skid-mounted units are ideal for commercial buildings, IT parks, resorts, and remote industrial project sites.

  • Pre-Engineered Efficiency: Factory-tested and assembled inside ISO containers or compact MS/FRP tanks, reducing civil construction work by over 80%.
  • Minimal Footprint: Optimized spatial configurations that can be seamlessly integrated into basements, parking lots, or semi-underground layouts.
  • Scalability: Modular designs allow parallel units to be added seamlessly as the site's population or wastewater volume expands.

2. Custom Built Civil & Turnkey STPs

Engineered for municipal bodies, massive industrial townships, and mega-residential townships requiring large-scale, long-term wastewater infrastructure.

  • Site-Specific Engineering: Full hydraulic and structural design of reinforced cement concrete (RCC) tanks engineered to handle high peak-flow factors and diurnal variations.
  • High Asset Longevity: Built using robust electro-mechanical equipment, advanced automated scraping mechanisms, and corrosion-resistant pipework designed for a 20+ year operational lifespan.
  • Odour & Noise Mitigation: Integrated acoustic enclosures for blowers and specialized forced-ventilation odour control systems (bio-filters/activated carbon) to ensure a neighborhood-friendly footprint.

Core Technology Implementations

·         SBR (Sequential Batch Reactor)

·         MBR (Membrane Bioreactor)

Engineering Highlights & Operational Value

The Tertiary Treatment Guarantee: All our STPs include a robust tertiary treatment train—combining Dual Media Filters (DMF), Activated Carbon Filters (ACF), and ultra-safe disinfection (Ozonation or UV)—ensuring the treated water is completely safe, pathogen-free, and legally compliant for reuse.

  • Automation Level (PLC-SCADA): Fully automated operational sequences with remote monitoring capabilities, minimizing manual intervention and lowering human error on-site.
  • Low Specific Power Consumption: Energy-optimized aeration patterns and high-efficiency IE3/IE4 motors significantly lower your monthly electricity overheads.
  • Value-Driven O&M Support: Backed by our dedicated Operations & Maintenance teams to handle routine testing, sludge dewatering (via filter press or centrifuge), and statutory compliance reporting.
