- SUSBIO ECOTREAT
- CPCB compliant
- 10-yr warranty
Packaged STP for hotels that guests never notice.
A factory-built Anaerobic + MBBR plant in a 100% FRP shell. It sits under your parking deck or lawn, runs silent and odourless, and is installed in 3–5 days. The treated water goes back to flushing, laundry pre-rinse and landscape.
Typical hotel range: 10–100 KLD. Capacity from 1 to 500 KLD across the ECOTREAT range.
Built for hotels
Four questions every hotel owner asks.
An STP has to stay out of everyone’s 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 the pool or the restaurant terrace.
Where will it fit?
Under the lawn, deck or driveway.
Underground or aboveground installation, with a footprint 40% smaller than a civil STP. Land stays for rooms and amenities.
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 6–25 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+ m²/m³ 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 hotel ends up in the drain. ECOTREAT returns it to work, and the reuse counts toward LEED and EDGE certification.

40 villas. Four leaking septic tanks. One ECOTREAT.
A 25 KLD ECOTREAT under the parking deck replaced the septic tanks. The treated water now irrigates the landscape and tops up the pool.

Size and cost
01What size STP does a hotel need?
Size depends on rooms, restaurant covers, laundry and banquet load. Hotels and resorts typically fall between 10 and 100 KLD. Send us your numbers and we will recommend a model and quote within 24 hours.
02How much does a packaged STP cost for a hotel in India?
Indicative SUSBIO ECOTREAT prices run from ₹9 L for 10 KLD to ₹32 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 hotel?
A packaged plant is factory-built and pre-tested, so it installs in 3–5 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 hotel 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 hotel?
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 hotel?
Installation takes 3–5 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 hotel 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. ECOTREAT’s typical outlet sits within every one of these limits.
08Does a hotel need pollution control board approval for its STP?
A hotel generally needs Consent to Establish (CTE) and Consent to Operate (CTO) from the state pollution control board. Requirements vary by state and property size. SUSBIO’s consultancy team supports both applications.
09Can treated STP water be reused at a hotel?
Yes. Treated water suits toilet flushing, landscaping, laundry pre-rinse, pool top-up, cooling-tower make-up. Reuse also counts toward LEED and EDGE certification.
Operation and service
10Does a hotel 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.
