Top 10 Effluent Treatment Plant Manufacturers in Noida
Drive through Noida's industrial sectors and you'll see the mix: pharma units, textile dyeing houses, food processing plants, chemical manufacturers, electronics assembly lines. All of them generate wastewater and none of them can legally discharge it untreated.
The CPCB and UPPCB don't go easy on this. Run without a working effluent treatment plant and you're looking at closure notices, penalties, or worse prosecution under the Environment Protection Act, 1986. Add to that the growing number of banks and export buyers who now ask for compliance documentation before they'll sign a deal, and an ETP stops being optional.
The harder question is which effluent treatment plant manufacturer to go with. You need someone who understands your specific wastewater a pharma plant's effluent has nothing in common with a textile unit's dye-heavy discharge plus the compliance know-how to keep regulators satisfied, and a team that still picks up the phone two years after commissioning. Below are the manufacturers currently active in and around Noida worth putting on your shortlist.

Leading ETP Plant Manufacturers Serving Noida (2026)
1. Netsol Water
Location: Greater Noida | Email: info@netsolwater.com
Fifteen-plus years in the business, over 500 installations, and clients spread across pharma, textiles, food processing, automotive, and chemicals. What tends to come up when engineers talk about them: they run an effluent characterization study checking BOD, COD, TDS, heavy metals before they draw up a design, rather than pushing a standard package regardless of what's in your wastewater. Their systems cover MBBR, SBR, MBR, ZLD, and RO polishing, and support doesn't stop at commissioning; there's an AMC option and a 24x7 line for when something breaks at an inconvenient hour.
2. VA Tech WABAG
Location: Global HQ Chennai, regional presence in NCR | Email: contact@wabag.com
This one's been around since 1924, operating in India since 1995, and now works across 25-plus countries. If your project is large and capital-heavy think municipal-scale or a big industrial park WABAG has the engineering bandwidth for it.
3. Thermax Limited
Location: HQ Pune, regional offices in NCR | Email: info@thermaxglobal.com
Better known for boilers and energy systems, but their water division has been quietly doing serious work for decades, particularly with high-strength effluent from chemicals, pharma, and refineries. They combine physico-chemical, biological, and membrane treatment, and tend to pitch the energy-efficiency angle alongside the treatment itself.
4. UEM India Pvt Ltd
Location: Noida | Subsidiary of Toshiba Water Solutions
Worth a mention simply because it's actually headquartered in Noida, not just "serving" it from somewhere else. Backed by Toshiba's engineering standards, they design and install treatment facilities for industrial and institutional clients.
5. Ion Exchange India
Location: HQ Mumbai, NCR regional office
Listed on the BSE 500, and one of the few players that manufactures its own resins and treatment chemicals rather than sourcing them out. That vertical integration shows up in projects spanning industrial, power, pharma, and municipal clients purification through to ZLD, under one roof.
6. Sewage Treatment Plants (Sec-16, Noida)
Location: Sector 16, Noida | Email: enquiry@sewagetreatmentplants.in
Runs an ISO-certified facility, offers both packaged and customized ETPs (MBBR, MBR, RO, advanced oxidation), and works mostly with textiles, chemicals, pharma, and food processing clients.
7. Urban STP Plant
Location: Sector 63, Noida | Email: info@urbanstpplant.com
Newer entrant, founded 2018, with a fairly narrow focus: ZLD-oriented recycling systems using UF, RO, and electro-deionization for textile, paper, pharma, and chemical clients.
8. Compact STP Plant
Location: Sector 18, Noida | Email: info@compactstpplant.com
Builds for high pollutant loads conventional systems as well as near-ZLD setups with evaporators and crystallizers when the discharge norms demand it.
9. Veolia Water Technologies India
Location: Pan-India | Email: enquiry.in@veolia.com
Part of a global environmental services group, so if you're running multiple sites across countries and want the same treatment standard everywhere, this is the kind of vendor that can deliver that consistency.
10. Sewage Doctor
Location: Noida | Email: enquiry@sewagedoctor.in
ISO 9001:2015 certified, handles design through O&M in-house, offers both conventional and ZLD configurations built around RO and advanced oxidation.
A quick note before you pick up the phone with any of these: certifications, project references, and even contact details can change. Verify directly rather than taking this list at face value.
How an ETP Works, in Short
Raw effluent goes through screening first (catches rags, packaging, debris), then equalization, which smooths out the flow so the rest of the plant isn't hit by sudden spikes. Oil and grease removal comes next if your industry produces it API separators or DAF units strip it out before it can poison the biological stage. Then physico-chemical treatment: coagulants and flocculants clump the fine particles and heavy metals together so they settle out as sludge. The biological stage (MBBR, SBR, or ASP) is where most of the actual pollutant breakdown happens, using microorganisms to eat through the BOD and COD. Finally, tertiary treatment UF, RO, disinfection and, if your discharge norms require it, ZLD, which recovers essentially all the water and leaves dry solid waste behind.
One thing worth remembering: skip the characterization testing at the start, and everything downstream is a guess. If a manufacturer proposes a design without first testing your effluent, that's a red flag.
Pollution Control Norms You Must Meet in Noida
Two regulatory bodies govern industrial effluent discharge in Noida. Both must be satisfied, and their requirements are not identical.
| CPCB (National) | UPPCB (State) |
|---|---|
| BOD ≤ 30 mg/L | ETP mandatory for Red/Orange category units |
| COD ≤ 250 mg/L | Online monitoring (OCEMS) for large units |
| TSS ≤ 100 mg/L | Regular third-party sampling |
| pH 6.5–8.5, Oil & Grease ≤ 10 mg/L | Sludge disposal via UPPCB-approved facilities only |
Ignore a closure notice long enough and it can turn into criminal proceedings against company directors not just a fine. There's also the buyer relationship to think about; international clients in pharma and textiles tend to walk away from suppliers with compliance problems. A manufacturer worth hiring designs with some headroom, so tomorrow's tighter norms don't mean tearing the plant out and starting over.
How We Ranked These Effluent Treatment Plant Manufacturers?
Project experience, CPCB/UPPCB compliance record, the range of technologies on offer (MBBR, SBR, MBR, ZLD), how well they handle different effluent loads, installation and after-sales support, and whether they've actually worked in your industry before.
ETP Plant Pricing and Specification
Price may vary based on the capacity and the level of automation.
| Capacity | Approx Price (INR) | Material and Features |
|---|---|---|
| 1 KLD | INR 5 Lakh | Prefabricated, MS-FRP |
| 5 KLD | INR 7 Lakh | Prefabricated, MS-FRP, Automatic |
| 20 KLD | INR 16 Lakh | MBBR Technology, PLC-based control |
| 50 KLD | INR 30 Lakh | Factory Fitted, Prefabricated, MS-FRP, Automatic |
| 100 KLD | INR 45 Lakh | Heavy-duty, MS-FRP, PLC Based control |
Before you sign anything: check that the technology actually fits your scale (MBBR works fine for smaller units, SBR tends to make more sense once you're bigger and want automation), get the water-quality guarantee in writing against CPCB/SPCB norms, understand what level of automation you're getting, and ask about chemical and energy costs that's what actually determines your running expense, not the sticker price.
Conclusion
You've got two broad options in Noida: large national or multinational players like VA Tech WABAG, Thermax, Ion Exchange India and Veolia, or regional specialists like Netsol Water and the other Noida-based manufacturers on this list. Neither is automatically the right call it comes down to your effluent, your budget, and how much runway you have before your compliance deadline. Pick for engineering depth and long-term support. The cheapest quote rarely stays the cheapest once the plant is actually running.
Frequently Asked Questions (FAQs)
Q1: What does an ETP cost in Noida?
A 1 KLD plant runs INR5 Lakh. A 20 KLD MBBR system is closer to INR14–20 Lakh. At 100 KLD with PLC/SCADA control, expect INR42–55 Lakh. And that's just the capital cost budget another 15–25% a year for running it.
Q2: Which is the best ETP manufacturer in Noida?
Depends on your scale. For a mid-sized unit in Noida or Greater Noida, a regional specialist like Netsol Water usually means faster response times. For something large or spread across multiple sites, national players like Thermax, VA Tech WABAG, or Veolia bring more engineering muscle. Either way, ask for reference projects before you decide.
Q3: MBBR vs SBR, what's actually different?
MBBR grows bacteria on plastic media floating in the tank; it's compact and forgives variable loads reasonably well. SBR runs everything through fill-react-settle-decant cycles in a single tank, which means higher automation and steadier output usually the better fit once you're operating at a larger scale.
Q4: How often does an ETP actually need attention?
Daily, someone should be checking flow, pH, dissolved oxygen, and dosing. Weekly: clean the screens, keep an eye on sludge levels. Monthly: service the pumps and blowers, inspect membranes if you're running MBR. Once a year: full overhaul plus the compliance testing you'll need for regulatory filings. Most manufacturers bundle this into an AMC, which is usually worth having.
Q5: Can an old ETP be upgraded instead of torn out and replaced?
Often, yes. Adding a tertiary RO or UF stage, retrofitting MBBR media into an existing aeration tank, bolting on SCADA automation, or fitting a ZLD module for a new mandate all of these are more common than starting from scratch, and usually cheaper too.
