How we engineer

How a water project runs: from assessment to optimisation.

A structured engineering journey — from the first site assessment and water analysis to commissioning, operation and continuous improvement over the plant's working life.

The Nine StagesETP & STP Pathways

The Engineering Journey

Nine Stages, Single-Point Accountability.

A comprehensive range of technical services, delivered as a complete solution — or as the specific stages a client needs.

Assess

Site assessment and audits of existing water and wastewater systems.

  • Plant & process audits
  • Water quality monitoring

Plays through all nine stages, then starts over. Choosing a stage or dragging the view pauses it.

ETP & STP

Industrial effluent and sewage — two pathways.

An effluent treatment plant is built around the characteristics of an industrial effluent; a sewage treatment plant around domestic and commercial sewage. Both end in treated water fit for reuse or compliant discharge.

Effluent Treatment Plant

Customised systems for the wide variety of industrial effluents — combining physico-chemical treatment, biological treatment and membrane separation to suit each effluent.

Typical treatment pathway

View in 3D

  1. 01Industrial wastewater

    Effluent from manufacturing and process operations.

  2. 02Characterization

    Understanding the effluent so the treatment train can be designed around it.

  3. 03Treatment

    Physico-chemical and biological processes reduce BOD and COD and maintain pH.

  4. 04Clarification / filtration

    Solids separation and filtration, with membrane separation where required.

  5. 05Reuse / discharge

    Recycling of treated water, or discharge — with minimum or zero discharge options.

Technologies often used

Sewage treatment clarifier with a scraper bridge, adjacent biological aeration tank and handrailed walkways
STP

Sewage Treatment Plant

Plants that treat domestic sewage, commercial wastewater and industrial process wastewater, delivering treated water that meets the discharge standards prescribed by the CPCB/SPCB.

Typical treatment pathway

View in 3D

  1. 01Domestic / commercial sewage

    Sewage from communities, campuses, buildings and institutions.

  2. 02Biological treatment

    A biological process such as MBR, MBBR, SAFF, SBR or extended aeration.

  3. 03Clarification / filtration

    Settling or membrane separation, followed by filtration.

  4. 04Treated water

    Disinfected treated water meeting the applicable standards.

  5. 05Reuse / discharge

    Recycling for non-potable uses, or compliant discharge.

Technologies often used

Pathways are conceptual. Each plant is designed around its own wastewater characteristics and discharge or reuse requirements.

Delivery

Delivered the way each client needs.

Complete solution

A full range of services from the initial stage of engineering and design through to construction and installation.

Tailored to the client

Every client has different requirements and resources — project delivery is shaped around them.

Design-bid-build

For clients who prefer the design-bid-build route, either the design engineering or the construction of the project.

In-house O&M

Operations and maintenance resources for operating water and wastewater treatment systems.
