Intellect Aqua designs, builds and maintains sewage treatment plants (STPs) in Chennai for apartments, IT parks, hospitals, hotels, schools and factories. With a branch office in West CIT Nagar and our head office and fabrication base in Coimbatore, we combine local site support with a design team that has delivered 700+ water and wastewater projects. Every plant we build is sized from a site study, not a standard model.
Why STPs Matter So Much in Chennai
Chennai lives with two water extremes. In dry years, borewells fall, Metro water supply is rationed and tanker bills soar. In the monsoon, low-lying areas flood and poorly built STPs overflow into storm drains. Both situations make a reliable STP essential.
For new buildings, planning and pollution control conditions require larger residential and commercial projects to treat their sewage. For existing buildings, a working STP is the key to reusing water for flushing and gardening — which directly cuts the amount of Metro or tanker water you need to buy. A well-designed plant also protects residents and neighbours from smell and overflow during heavy rain.
STP Technologies We Build in Chennai
MBBR – Moving Bed Biofilm Reactor
Compact, robust and easy to operate. MBBR is our default choice for most apartments and commercial buildings along OMR, GST Road and the western suburbs. Read more about MBBR technology.
MBR – Membrane Bioreactor
Very clear treated water in the smallest footprint. MBR suits hospitals, premium apartments and basement plants where space is limited and reuse is a priority. Read more about MBR technology.
SBR – Sequencing Batch Reactor
Batch treatment in one tank, ideal where flow varies a lot, such as schools, colleges and hotels. Read more about SBR technology.
Civil and Packaged STPs
Civil plants suit new construction and larger capacities. Packaged FRP or MS plants install quickly and suit existing buildings, tight plots and phased projects.
Designing STPs for Chennai Conditions
Chennai sites bring specific challenges, and we design for them:
- Flood risk: Plant rooms, panels and blowers are placed above expected flood levels where possible, and tanks are protected from storm water entry.
- High groundwater: In coastal and low-lying areas, underground tanks need careful waterproofing and uplift protection.
- Corrosion: Salt-laden air near the coast corrodes MS equipment, so we choose FRP, SS or properly coated materials.
- Basement plants: Many city projects place the STP under parking, so ventilation, odour control and access for sludge removal are planned early.
- Reuse demand: With expensive water, we design tertiary treatment so treated water is genuinely reusable.
STP Price in Chennai
| Capacity | Typical use |
|---|---|
| 10 KLD | Small apartment (about 20 flats), small hotel |
| 25 KLD | Mid-size apartment, clinic, school |
| 50 KLD | Large apartment, hospital, office |
| 100 KLD | Gated community, IT campus |
Price depends on technology, civil or packaged build, reuse quality, automation and site conditions. We share an exact quote after a free site visit, including monthly running cost.
Who We Build STPs For in Chennai
- Apartments and gated communities: See STP for apartments in Chennai.
- Hospitals and nursing homes: See STP for hospitals in Chennai.
- IT parks and offices: Large daytime loads with strong reuse potential for flushing and cooling towers.
- Hotels and restaurants: Peak-flow design for weekends and events.
- Schools, colleges and hostels: Plants that handle holiday low-flow periods.
- Factories: Domestic sewage from staff and canteens. Process wastewater needs an ETP.
