ETP and STP plants in Ahmedabad. Designed in Rajpura, commissioned on your site.
ETPs for textile processing, dyes and chemicals, pharma and engineering units across Narol, Vatva, Naroda, Odhav, Changodar and Sanand.
Trusted by















Ahmedabad industries we design for Each cluster has its own effluent. So does each plant we design.
Textile & dyeing
Textile processing and dyeing houses in Narol and the eastern estates, where effluent has to meet the CETP’s inlet norms before it leaves your site.

Engineers on your site
Our engineers travel from Rajpura for the site survey, installation supervision and commissioning. Filters are dispatched in 30–45 days.
30+ years of plant design
Every plant is designed by engineers with three decades of ETP and STP experience, not by a sales team.
Chemical-free wherever possible
No daily dosing and no chemical sludge for most effluents. Dyeing and electroplating get a chemical step only where it is unavoidable.
Commissioning guaranteed
Designed within Gujarat Pollution Control Board norms, or your CETP’s inlet norms, and commissioned by our engineers to work at the agreed flow and load. Any board query about our design is answered by us.

Chemical-free by design.
Wherever your effluent allows, our plants run without daily chemical dosing. There is no chemical sludge to store, transport or pay to get rid of.
- No chemical sludge, only pure biological sludge
- Dried on simple sludge beds, so disposal costs almost nothing
- Can be used as manure instead of being trucked away
What you get
- Site audit and effluent analysis before any design
- Process design and DPR sized to your flow and board discharge norms
- Clarifiers and MGF + ACF filters supplied by us
- Installation supervision by our engineers
- Commissioning by our engineers, guaranteed to work at the agreed design flow and load
- Board queries answered by us: any pollution control board question about our design or equipment
Questions
Do you take projects in Ahmedabad?
Yes. Our engineers travel from Rajpura for the site survey, installation supervision and commissioning, across Narol, Vatva, Naroda, Odhav, Changodar, Sanand and the rest of the city.
Can you design pre-treatment to meet our CETP’s inlet norms?
Yes. We design the ETP around your CETP’s inlet limits, so your effluent is accepted without problems.
Is your treatment chemical-free for dyeing units?
Mostly. Colour removal from dyeing effluent needs a chemical step. We size it to your dye load and keep the rest of the plant biological.
Our ETP isn’t performing. Can you fix it instead of building a new one?
Yes. We audit the plant, test the effluent and upgrade the stages that are failing, instead of building a new one.
