- SUSBIO ECOTREAT
- CPCB compliant
- 10-yr warranty
Packaged STP for industries and factory campuses.
Treat the domestic sewage from your workforce in a factory-built Anaerobic + MBBR plant that runs alongside your ETP. Reuse the water in cooling towers and cut freshwater intake. For process effluent, see our ETP range.
Capacity from 1 to 500 KLD. Custom skids and multi-unit setups beyond 500 KLD.
Built for industries
Four questions every industrial site owner asks.
An STP has to stay out of everyoneās way. Here is how ECOTREAT answers the doubts we hear most.
Will it smell?
Sealed, silent, odourless.
The plant runs inside a closed FRP vessel, rated under 45 dB. It can sit close to offices and the canteen.
Where will it fit?
Under the lawn, deck or driveway.
Underground or aboveground installation, with a footprint 40% smaller than a civil STP. Plant space stays for production.
Who runs it?
Nobody on your payroll.
No permanent on-site operator. IoT and SCADA-ready monitoring, plus lifetime service from SUSBIO.
Will it pass inspection?
Built to CPCB and NGT 2019 norms.
Outlet beats Class A. Our consultancy team handles CTE and CTO paperwork with your state pollution control board.
How it works
Six stages. One FRP vessel.
Dual-stage biological treatment, factory-built and pre-tested, then set into a PCC pit on your site.
- 01
Screening
A 6ā25 mm coarse screen stops rags, plastics and kitchen solids.
- 02
Primary settling
A buffer chamber with 4 hr HRT evens out the morning and evening peaks.
- 03
Anaerobic reactor
Hydrolysis and acidogenesis break down the heavy organic load first.
- 04
MBBR aeration
K1/K3 media carriers with 600+ mĀ²/mĀ³ surface area do the fine polishing.
- 05
Settler
The clarifier separates biomass so the water leaving is clear.
- 06
Disinfection and reuse
UV or chlorine polish, then a tank ready for flushing and landscape lines.

Water you already paid for
Treat it. Reuse it. Count the points.
Most of the water used in a industrial site ends up in the drain. ECOTREAT returns it to work, and the reuse counts toward LEED and EDGE certification.

Size and cost
01What size STP does a industrial site need?
Size depends on headcount, canteen, hostel and shift pattern. Send us your numbers and we will recommend a model and quote within 24 hours.
02How much does a packaged STP cost for a industrial site in India?
Indicative SUSBIO ECOTREAT prices run from ā¹9 L for 10 KLD to ā¹32 L for 75 KLD (May 2026), including design, manufacture, installation and commissioning. Transport and civil works are extra, and the final price depends on your configuration.
03Why choose a packaged STP over a civil STP for a industrial site?
A packaged plant is factory-built and pre-tested, so it installs in 3ā5 days instead of weeks of civil work. Compared with a civil RCC STP, ECOTREAT needs 40% less footprint and 70% less electricity, and runs without a permanent on-site operator.
Installation and comfort
04Can a industrial site STP be installed underground?
Yes. ECOTREAT is set into a PCC pit and can be installed underground or aboveground. Its footprint is 40% smaller than a civil RCC STP, so land stays free for other uses.
05Will an STP smell or make noise near a industrial site?
No. The plant runs inside a closed FRP vessel with silent, odourless operation, rated under 45 dB.
06How long does it take to install a packaged STP at a industrial site?
Installation takes 3ā5 days on site once the civil pad is ready. From purchase order to commissioning, plan for under 4 weeks.
Approvals and water reuse
07What discharge standards must a industrial site STP meet in India?
CPCB norms under NGT 2019 set limits of BOD below 10 mg/L, COD below 50, TSS below 10, total nitrogen below 10, total phosphorus below 1 and faecal coliform below 100 MPN/100 mL. ECOTREATās typical outlet sits within every one of these limits.
08Does a industrial site need pollution control board approval for its STP?
A industrial site generally needs Consent to Establish (CTE) and Consent to Operate (CTO) from the state pollution control board. Requirements vary by state and property size. SUSBIOās consultancy team supports both applications.
09Can treated STP water be reused at a industrial site?
Yes. Treated water suits cooling-tower make-up, landscaping, toilet flushing, washing, construction curing. Reuse also counts toward LEED and EDGE certification.
Operation and service
10Does a industrial site STP need a full-time operator?
No. ECOTREAT needs no permanent on-site operator. It is IoT and SCADA-ready, so performance can be monitored remotely.
11What warranty and service come with a SUSBIO ECOTREAT STP?
A 10-year module warranty and lifetime service from SUSBIO. The FRP vessel is designed for a 50-year life.
