Intellect Aqua designs, builds and maintains sewage treatment plants (STPs) in Coimbatore for apartments, hospitals, hotels, schools and factories. Our head office is in Siddhapudur, so our engineers can visit your site, study your sewage load and recommend the right plant within days. With 700+ projects and more than 15 years in water and wastewater treatment, we build STPs that keep working long after handover — not just on the day of commissioning.
Why Coimbatore Buildings Need a Properly Designed STP
Coimbatore is growing fast along Avinashi Road, Saravanampatti, Kalapatti and Trichy Road. Every new apartment block, hospital, IT campus and hotel has to treat its sewage before it is discharged or reused, and the consent conditions from the Tamil Nadu Pollution Control Board (TNPCB) decide the treated-water quality the plant must achieve.
A plant that is sized only on paper usually fails in real use. The common problems we are called in to fix are overloaded aeration tanks, bad smell near the plant room, sludge escaping into the treated water and outlets that never meet reuse quality. A correctly designed STP avoids all of these and lets you reuse treated water for flushing, gardening and cooling towers — cutting tanker water bills in summer.
STP Technologies We Build in Coimbatore
We do not push one technology for every site. We look at your daily flow, available space, power cost and how you plan to use the treated water, then recommend the option that fits.
MBBR – Moving Bed Biofilm Reactor
MBBR uses floating plastic media on which bacteria grow and break down organic waste. It is compact, handles changes in load well and is easy to operate, which makes it the most popular choice for apartments and commercial buildings in Coimbatore. Read more about our MBBR sewage treatment plants.
MBR – Membrane Bioreactor
MBR combines biological treatment with membrane filtration. It gives the clearest treated water and needs the least floor space, so it suits hospitals, premium apartments and any project that wants to reuse most of its water. Read more about MBR sewage treatment.
SBR – Sequencing Batch Reactor
SBR treats sewage in batches inside one tank — fill, aerate, settle and decant. It works well where flow changes sharply through the day, such as schools, colleges and layouts. See our SBR sewage treatment plants.
Civil STP or Packaged STP?
A civil STP is built with concrete tanks on site and suits larger capacities and new construction. A packaged STP comes as factory-built FRP or MS tanks, installs faster and is ideal for existing buildings, tight plots and capacities up to medium size. We build both and will tell you honestly which one makes sense for your site.
STP Price in Coimbatore
The cost of a sewage treatment plant depends on capacity, technology, civil or packaged build, automation level and how far the treated water must be polished for reuse. As a rough guide to sizing, a residential building generates about 0.5 KL of sewage per flat per day.
| Capacity | Typical use |
| 10 KLD | Small apartment (about 20 flats), small hotel |
| 25 KLD | Mid-size apartment, clinic, school |
| 50 KLD | Large apartment, hospital, factory canteen |
| 100 KLD | Gated community, large hospital, campus |

Who We Build STPs For
Apartments and Gated Communities
Builders and residents' associations need a plant that runs quietly, does not smell and is cheap to operate. Learn more about our STP for apartments in Coimbatore.
Hospitals and Healthcare
Hospitals generate high and continuous sewage loads and often need reuse-quality water. See our STP for hospitals.
Hotels, Schools, Colleges and Offices
Flow from these buildings rises and falls sharply during the day, so the plant must be sized for peaks, not averages.
Factories and Industrial Units
We treat the domestic sewage from your staff toilets and canteen. Process wastewater from manufacturing needs a separate effluent treatment plant.
