Mohali industries we design for Each cluster has its own effluent. So does each plant we design.
Pharmaceutical
Bulk drug and formulation units in Derabassi and along the Barwala road, where strong, variable streams need careful design and often a ZLD stage.

Hotels & resorts
Occupancy that swings with the season, kitchen and laundry load, and guests who must never notice the plant.

Under an hour away
We are based in Rajpura, under an hour from Mohali and Derabassi. Site visits, commissioning and follow-ups happen without travel delays.
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. Where a pharma or chemical stream needs a chemical or ZLD stage, we say so upfront.
Commissioning guaranteed
Designed within Punjab Pollution Control Board 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 Mohali?
Yes. We are based in Rajpura, under an hour away, and work across Mohali’s industrial phases, Derabassi, Lalru, Kharar and Zirakpur, for factories as well as hospitals, hotels and housing societies.
Can you design ZLD for a pharma unit in Derabassi?
Yes. We design ETPs with a ZLD stage where your effluent or your consent needs one, and keep the biological stages chemical-free wherever the effluent allows.
Our housing society’s STP isn’t working. Can you fix it?
Yes. We can upgrade any and every STP. We audit the plant, check which stages are failing and upgrade them, instead of rebuilding it.
Do you supply equipment as well as the design?
Yes. We supply clarifiers and MGF + ACF filters, our engineers supervise installation, and we commission the plant ourselves.
