  • Offers rental/leasing models and flexible ownership structures

Sewage Treatment Plants use of cutting-edge treatment processes in containerized all-weather steel units makes it a noteworthy STP plant manufacturer meeting Gurugram’s growing de-centralized treatment requirements.

Conventional vs Containerized STPs

Conventional STP plants use civil tanks constructed onsite for various treatment processes and are preferred for extensive centralized facilities (over 5 MLD). Containerized STP plants house the treatment modules in weatherproof steel containers that can be manufactured offsite and plugged in on location during installation.

Prominent Technologies Used in Gurugram STPs

The top STP plant manufacturers in Gurugram employ a mix of conventional and advanced technologies at various treatment stages:

Primary screening, Raw sewage pumps, V-notch metering for flow measurement

Primary Treatment – Oil & Grease Traps, Dual Media Filters for suspended solids removal

Secondary Treatment Technologies:

  1. Activated Sludge Process (ASP) – Flocculated biological treatment; needs large footprint
  2. Sequential Batch Reactor (SBR)- Cyclic aeration based sludge process
  3. Moving Bed Biofilm Reactor (MBBR)- Biofilm carriers instead of flocs; compact
  4. Membrane Bioreactor (MBR) – Ultrafiltration membranes for solid-liquid separation

Tertiary Treatment – Dual media filters, Activated carbon &Antiscalant dosing

Disinfection – Chlorine, Ozonation, UV radiation

Clarifiers, Sludge pumps, and Sludge suction-recirculation also form critical equipment. Advanced STPs also incorporate SCADA, PLCs and remote performance monitoring.

Key Project Considerations for Clients

Sewage treatment requires significant technical understanding. Clients must evaluate proposals from manufacturers on the following aspects:

  1. Treatment performance guarantees and plant sizing calculations
  2. Technology suitability for the influent sewage characteristics
  3. Equipment quality and automation levels proposed
  4. Energy efficiency commitments and operating expense estimates shared
  5. Clarity on ownership operation and& Maintenance responsibility post-installation
  6. Transparency in costs broken up into equipment, construction, and civil works for complete visibility
  7. Acceptance of performance-linked payouts compared to fixed turnkey cost model
  8. Post-installation commitments like defect liability period, warranties on equipment life
  9. Operator manual, training and technical support during initial plant functioning

Undertaking due diligence across the above parameters right at the vendor/bid evaluation stage helps clients derive the best value over the entire lifecycle.

STP Operation & Maintenance Requirements

The smooth running of the treatment process day after day relies on strict operation protocols and preventive maintenance disciplines:

  1. Ensuring uninterrupted electricity supply and DG backup for 24X7 plant functioning
  2. Conducting Daily system checks before startup
  3. Routine pre/post-treatment testing and maintaining proper treatment parameters
  4. Regular cleaning of screening channels, grit channels and clarifier surface
  5. Checking oil & grease in rotating equipment and replacing filtration media
  6. Tracking secondary treatment efficiency and biofilm/MLSS health parameters
  7. Sludge volume monitoring and scheduled sludge withdrawal
  8. Chemical replenishment for disinfection systems
  9. Record-keeping of all process parameters and consumption data
  10. Annual maintenance contracts for equipment overhaul, parts replacement etc.

Entrusting O&M responsibility to the EPC vendor or qualified third-party service providers right from the commissioning stage ensures sustainable and effective asset functioning.

The Future – More Decentralization, Recycling & Reuse

Gurugram’s further growth requires a decentralized approach to sewage treatment and over-reliance on a few large STPs. Small localized containerized STPs will emerge closer to office parks, apartments, and land parcels under the reuse and recycling focus. Instead of discharging treated sewage, industrial STPs will recycle and reuse treated effluent in cooling towers or send it to districts for agricultural use through dedicated underground conveyance pipelines built under the Gurugram Water Policy. The next decade should see 25–30% of the sewage generated being recycled back into non-potable usage to conserve freshwater abstraction. Leading STP manufacturers are already geared to enable this sustainable transformation.


With advanced treatment processes, high-quality equipment, automation, and professional maintenance services, the top 3 sewage treatment plant manufacturers in Gurugram address growing residential and industrial needs while meeting environmental norms. As decentralized systems gain more prominence, plug-and-play containerized STPs will drive faster and more flexible capacity expansion aligned with Gurugram’s ambitions of closing the water loop through recycling and reuse over the next decade.
