Sewage treatment plant

Safe treatment for domestic wastewater

Every building produces sewage from toilets, kitchens and bathrooms. Without treatment, it pollutes canals, rivers and groundwater and creates serious health risks — especially in dense cities like Dhaka and Chattogram.

A sewage treatment plant (STP) uses natural biological processes to break down waste, then clarifies and disinfects the water. The treated water can be discharged safely or reused for flushing, gardening and cooling.

Buildings that benefit from an STP

  • Residential towers and housing projects
  • Hospitals and clinics
  • Hotels, resorts and shopping complexes
  • Factories with large workforces

Why clients rely on us

Engineering you can depend on

A trusted partner

Homes, factories, hospitals and institutions across Bangladesh rely on our plants for safe water every day. We treat every project as a long-term relationship, not a one-time sale.

Quality at every step

We select vessels, membranes, media and pumps that suit local water conditions, and we test the treated water before handover so you can see the result for yourself.

Modern treatment technology

RO, UF, ion exchange, multimedia filtration, UV and automated controls — we combine proven technologies into a plant that is efficient to run and simple to operate.

Why untreated sewage is a serious problem

The risk

Why untreated sewage is a serious problem

Septic tanks alone cannot cope with the load from large buildings. Overflowing tanks and direct discharge affect everyone nearby.

  • Health hazards

    Spreads waterborne diseases such as diarrhoea and typhoid.

  • Water pollution

    Contaminates canals, rivers and ponds used by communities.

  • Odour & insects

    Causes bad smells and mosquito breeding around the building.

  • Approval requirements

    Large buildings increasingly need on-site treatment for approvals.

  • Groundwater contamination

    Leaking tanks pollute the aquifers we drink from.

  • Wasted water

    Sewage that could be treated and reused is simply lost.

Treatment stages

How a sewage treatment plant works

A compact biological process with minimal odour.

  1. 1

    Screening & grease trap

    Removes solids, plastics, oil and grease.

  2. 2

    Equalisation

    Balances peak flows from morning and evening use.

  3. 3

    Aeration

    Bacteria digest organic matter with supplied air.

  4. 4

    Clarification

    Treated water separates from settled sludge.

  5. 5

    Filtration & disinfection

    Sand/carbon filters and chlorination or UV.

  6. 6

    Sludge handling

    Excess sludge is stored and removed periodically.

Why install

Benefits of a sewage treatment plant

  • Safe discharge

    Treated water meets discharge limits for BOD and solids.

  • Water reuse

    Use treated water for flushing, gardening and cooling towers.

  • Compact footprint

    Package and underground designs fit tight city plots.

  • Low odour

    Enclosed, aerated design keeps smells under control.

  • Lower water bills

    Reuse cuts demand for fresh supply water.

  • Environmental responsibility

    Protects local waterways and public health.

Sewage treatment plant — FAQ

What size STP does my building need?

STP capacity is based on the number of residents or users and daily water use per person. We calculate this during the site survey.

Can the STP be installed underground?

Yes. Many of our compact plants are built underground or in the basement to save space.

Can treated water be reused?

Yes, for non-drinking purposes such as flushing, gardening, floor washing and cooling towers.

How much maintenance does an STP need?

Routine checks of blowers and pumps, periodic sludge removal and regular testing. We offer maintenance contracts for hands-free operation.
