STP and ETP Plant Manufacturer in Delhi/NCR

Trusted Wastewater Treatment Partner Across Delhi NCR

Delhi NCR is one of India's most industrially and commercially dense regions, with millions of litres of sewage and industrial effluent generated every day across its factories, residential townships, hotels, hospitals, and infrastructure projects. Regulatory scrutiny from the Central Pollution Control Board (CPCB) and Delhi Pollution Control Committee (DPCC) has intensified, and discharge norms are non-negotiable.

Trity Environ Solutions designs, manufactures, installs, and commissions Sewage Treatment Plants (STP) and Effluent Treatment Plants (ETP) across Delhi, Noida, Greater Noida, Ghaziabad, Gurugram, Faridabad, Manesar, Bahadurgarh, Sonipat, and surrounding industrial clusters. Our engineering teams work directly from site assessment through long-term plant operation, delivering turnkey solutions that are built to comply, built to last, and built to perform.

STP and ETP Solutions in Delhi NCR

Delhi NCR presents a distinct wastewater engineering environment: high population density, mixed land use, aggressive industrial discharge, varying influent characteristics, and limited space for large-scale civil infrastructure. Off-the-shelf plants do not work here.

Our STP and ETP designs for Delhi NCR account for:

• Variable influent flow during peak and off-peak operational cycles
• High BOD and COD loads from food processing, pharma, and textile units in Okhla, Sahibabad, and Noida Phase II
• Space-constrained sites in dense commercial zones requiring compact modular systems
• CPCB/DPCC discharge standards for BOD, TSS, COD, oil and grease, and heavy metals
• Water reuse requirements for flushing, cooling, horticulture, or process recycling

Whether your project is a high-rise residential society in Gurugram, a food processing unit in Bahadurgarh, or a pharmaceutical cluster in Greater Noida, we engineer the plant around your site conditions and regulatory obligations.

Our STP Plant Manufacturing Services

We manufacture Sewage Treatment Plants across a capacity range of 10 KLD to 10 MLD and above. Our STP manufacturing services for Delhi NCR clients include:

• STP design and engineering for residential complexes, IT parks, hotels, hospitals, and institutional campuses
• Prefabricated and modular STP systems for projects with space constraints or fast mobilisation requirements
• Civil STP plants for large-scale municipal and industrial townships
• Selection between MBBR technology, SBR, MBR, FAB, and activated sludge-based systems based on influent load and reuse targets
• Integrated sludge handling with filter press systems and sludge drying beds
• Tertiary polishing including activated carbon filters, multi-grade filters, and UV disinfection for treated water reuse
• Complete instrumentation, control panels, and SCADA integration

Our ETP Plant Manufacturing Services

Effluent Treatment Plants for industrial clients in Delhi NCR must handle complex wastewater streams. We design and manufacture ETPs that address:

• High COD and BOD effluent from food and beverage processing units
• Toxic heavy metal removal for electroplating, battery, and chemical industries
• Oil and grease separation using oil skimmers and dissolved air flotation
• High TDS and suspended solids from paper, textile dyeing, and printing units
• Colour removal for textile and garment industries in Gurugram and Faridabad
• Pharmaceutical and API effluent treatment requiring multi-stage biological and chemical treatment
• ZLD-ready ETP design integrating Zero Liquid Discharge systems with evaporators and condensate recovery

Our ETP manufacturing process is driven by laboratory-level influent characterisation, mass balance calculation, and process simulation before a single component is ordered.

Turnkey Design, Engineering and Installation

We execute complete turnkey STP and ETP projects across Delhi NCR, covering every stage from initial site survey to handover and beyond:

1. Site assessment and influent characterisation -- flow measurement, sampling, laboratory analysis
2. Process design and engineering -- hydraulic calculations, mass balance, unit operation selection
3. Civil and structural design -- reactor sizing, tankage, piping layout
4. Procurement and manufacturing -- in-house manufacturing with vendor-qualified components
5. Erection and installation -- mechanical, electrical, instrumentation, and civil works
6. Commissioning and performance testing -- against CPCB/DPCC discharge norms
7. Operator training and documentation -- SOPs, maintenance schedules, operational manuals
8. Long-term AMC and O&M services -- structured maintenance contracts

This end-to-end control eliminates coordination gaps between design, supply, and installation, resulting in faster commissioning and fewer on-site delays.

Plant Capacity Options

All capacities are engineered to handle peak flow conditions -- typically 2x to 3x average daily flow -- without process upset or bypass.

Treatment Technologies We Deploy

Biological Treatment

• MBBR (Moving Bed Biofilm Reactor) -- compact, resilient to load variation, low sludge generation; uses MBBR media engineered for high specific surface area
• SBR (Sequencing Batch Reactor) -- ideal for residential STPs needing consistent effluent quality
• MBR (Membrane Bioreactor) -- high-quality tertiary treated output for direct reuse applications
• FAB and Extended Aeration -- proven low-cost technologies for mid-scale applications

Physical and Chemical Treatment

• Primary clarification with tube settler media for enhanced TSS removal in compact footprints
• Coagulation and flocculation for suspended solids and colour removal
• DAF (Dissolved Air Flotation) for oil and grease separation in industrial ETPs
• pH correction and chemical dosing systems

Tertiary and Advanced Treatment

• Ultrafiltration systems for treated water polishing
• Commercial RO Plant integration for high-purity water recovery
• Demineralised water treatment for process water recovery
• Activated carbon filters for colour, odour, and residual organics removal

Customised Plant Design

No two wastewater streams are identical. A textile unit in Sahibabad produces a fundamentally different effluent from an automotive plant in Manesar or a hospital in Gurugram. Our design process starts with characterising your specific influent parameters -- BOD, COD, TSS, TDS, pH, oil and grease, heavy metals, colour, and flow rate -- and builds the treatment train around those numbers.

Where water reuse is the target, we design for the output quality required. Where discharge to the sewer is the only goal, we size for compliance at minimum capital and operating cost. Where ZLD is mandated, we integrate Zero Liquid Discharge systems with the biological and physical treatment stages.

Customisation also extends to space and civil constraints. Compact modular plants on steel skids can be installed in machine rooms. Prefabricated containerised plants work on sites with minimal civil construction time. Conventional RCC-based plants are designed for long-term capacity expansion.

Factors Affecting Plant Selection

Several technical and commercial factors determine the right STP or ETP configuration for your Delhi NCR project:

• Daily flow volume and diurnal variation pattern
• Influent BOD, COD, and TSS concentrations -- higher loads require longer hydraulic retention times
• Space available for civil infrastructure -- compact sites need modular or MBR-based designs
• Treated water end use -- flushing and horticulture have different quality targets than process reuse
• Power availability -- sites with frequent outages need battery backup or generator provision
• ZLD obligation -- whether CPCB or NGT has mandated zero liquid discharge for your industry category
• Timeline -- prefabricated plants can be installed in 45 to 90 days; civil plants take longer

Environmental Compliance

All plants we supply are engineered to comply with:

• CPCB General Standards under Environment Protection Act (EPA) 1986
