Engineering works
Design, equip, support.
Alongside the environment and water activities, EWES carries out engineering works: analytical instruments, building construction, IT and electricity.

- 01
Analytical instruments
Advice, supply, repair and training: pH meters, conductivity meters, gas analysers, and more.
- 02
Building construction
Computer-aided design, scale models, computer-aided site supervision and training in construction software.
- 03
IT
An IT activity complements EWES’s engineering offering.
- 04
Electricity
Engineering works in the field of electricity.
From sampling to report.
We measure before we conclude: our recommendations rest on data collected, analysed and modelled locally.
- 01
Regulatory scoping
Analysis of the project and the applicable environmental obligations, then definition of the study scope.
- 02
Fieldwork & sampling
On-site surveys and sampling of water, soil and air.
- 03
Laboratory & modelling
Analyses, data processing and modelling of how the environment may evolve under different scenarios.
- 04
Report, compliance & transfer
Impact assessments, management plans, annual reports and remediation plans, followed by training for your teams so the results last.
Serving companies, the State and research.
Mining, oil and mineral sectors
Feasibility studies, optimisation of operating conditions, environmental incidence studies.
The Congolese State
Environmental audits, restoration of polluted sites, characterisation of deposits on concessions to be awarded.
Continuing education
Coaching and refresher training for staff and managers of mining and mineral companies based in the DRC.
Researcher supervision
Support for private and public sector researchers in environment, water and engineering works.

Strengthening the skills of local stakeholders.
Training is an essential part of EWES’s activities: the company shares its expertise with managers and technicians of mining and oil companies, as well as with the public services in charge of the environment in the Democratic Republic of Congo.
