From feasibility to site supervision

Eight service areas, from wastewater treatment plant design to construction, equipment and commissioning, plus sewerage, drinking water and solid waste. Each is available on its own or as part of a complete project.

Wastewater treatment plants

Starting from population and flow projections, we select the treatment technology, size the units and prepare the design for approval together with the civil, mechanical and electrical disciplines. Rehabilitation and capacity extension of existing plants are part of this work.

Scope

  • Process selection and unit sizing
  • Hydraulic profile and mass balance
  • Biological treatment and nutrient removal
  • Sludge line
  • Package treatment plants
  • Rehabilitation and deep-sea outfalls

Industrial wastewater

We start with characterising the wastewater, then design pre-treatment, chemical and biological stages to meet the discharge standards. Where process water or reuse matters, we look at the whole water cycle of the site.

Scope

  • Wastewater characterisation and load calculation
  • Pre-treatment, chemical treatment, equalisation
  • Central plants for industrial zones
  • Power plant wastewater
  • Process water and reuse

Water and sewer networks

We size water supply and wastewater collection systems with hydraulic models and choose routes, materials and pumping stations with operating costs in mind.

Scope

  • Drinking water networks and transmission lines
  • Water pumping stations and reservoirs
  • Sewer and stormwater networks
  • Trunk sewers
  • Wastewater pumping stations

Solid waste

We design transfer stations, sanitary landfills and the rehabilitation of old dumpsites, based on waste quantities and collection logistics.

Scope

  • Solid waste transfer stations
  • Sanitary landfills
  • Dumpsite rehabilitation
  • Leachate management

Feasibility and reporting

We prepare the technical and economic analyses behind an investment decision: comparison of alternatives, cost estimates, creditworthiness analysis and the environmental management plans lenders require.

Scope

  • Feasibility studies
  • Creditworthiness analyses
  • Project information reports
  • Environmental management plans
  • Investment cost estimates

Tendering and site supervision

To make sure a design is built as intended, we prepare specifications, quantity take-offs and tender documents, and take on site supervision and site management during construction.

Scope

  • Technical specifications
  • Quantity take-off and cost estimate
  • Tender documents and site surveys
  • Construction supervision
  • Site management
  • Material selection and installation

WWTP construction and technical consulting

We support every stage of construction so the detailed design is built as intended: inspection of works, scheduling, progress payments and quantity support, and resolving design changes on site. Where required, we also deliver design, construction, equipment supply and commissioning under a single contract as a turnkey wastewater treatment plant.

Scope

  • Turnkey wastewater treatment plants
  • Technical consulting during construction
  • Transfer of the detailed design to site
  • Inspection and quality control
  • Scheduling, progress payments and quantities
  • Site changes and as-built drawings

Equipment supply, installation and commissioning

From inlet screens to sludge dewatering, we select treatment equipment to suit the process, coordinate supply and installation, commission the plant and hand it over to the operating staff.

Scope

  • Mechanical screens
  • Grit and grease removal equipment
  • Penstocks and channel gates
  • Pumps, blowers and diffuser systems
  • Sludge dewatering equipment
  • Commissioning and operator training

How a project runs

The same team at every stage: the engineer who makes the design decisions also follows them on site.

  1. Survey and feasibility

    Existing conditions, population and flow projections, technical and economic comparison of options.

  2. Process design

    Choice of treatment technology, unit sizing, hydraulic profile and mass balance.

  3. Detailed design and approval

    Coordinated civil, mechanical and electrical design; approval by the client and the ministry.

  4. Tender documents

    Specifications, quantities and cost estimate in a tender-ready package.

  5. Construction and commissioning

    Site supervision, site management and commissioning support.
