Is an STP legally required in Bangladesh?

Yes. Buildings above a certain size and any factory generating domestic sewage are required by DoE and RAJUK to install an STP.

Can I reuse STP treated water?

Absolutely. Our STPs deliver treated water at BOD < 10 mg/L, suitable for flushing, gardening and cooling towers.

No. Our plants are fully enclosed with vent scrubbing, so they are odour-free even in basements.

How We Deliver

Step 1
Load & reuse assessment
We calculate real occupancy, per-capita flow and how much recycled water your property can actually reuse.
Step 2
Right-fit technology
MBBR, SBR or MBR — chosen by footprint, reuse quality and OPEX, never one-size-fits-all.
Step 3
Turnkey build
Civil, tanks, blowers, panels and piping — installed and commissioned by our own crew, not sub-contracted.
Step 4
Lifetime support
AMC with monthly lab reports, spares, chemicals and 24-hour breakdown response.

Introduction

A Sewage Treatment Plant (STP) treats domestic wastewater from buildings, factories, hotels and townships so the outlet water is safe to reuse or discharge. Our STPs are compact, odour-free and fully automatic — designed for Bangladesh's density, humidity and load patterns.

What is a Sewage Treatment Plant?

An STP removes organic matter, suspended solids, nutrients and pathogens from black and grey water. Modern packaged STPs use biological processes so the treated water can be reused for flushing, gardening, cooling towers and floor washing — cutting WASA bills substantially.

STP technologies we build

We match technology to reuse quality, footprint and budget:

MBBR — the most popular for buildings and factories; low OPEX, forgiving of load swings.
SBR — batch-based, small footprint, excellent effluent quality.
MBR — membrane-polished output ready for direct reuse, best for hotels and hospitals.

Where our STPs are used

From a 5 m³/day rooftop package for a single building to a 5 MLD municipal plant, our STP portfolio covers residential towers, garment factories, hospitals, hotels, resorts and corporate campuses.
