01 · About us
Born at the university, proven in the field.
EWES grew out of the Environment Centre of the University of Lubumbashi–Society Interface, working with Belgian, French and Canadian partners. Its team brings together Congolese and international experts.
The company has established itself in drawing up and assessing the environmental plans of mining and oil projects. It studies natural and man-made risks, develops sites, supports environmental compliance and trains the sector’s managers and technicians.

Building constructionComputer-aided design, scale models, computer-aided site supervision and training in construction software.
ITAn IT activity complements EWES’s engineering offering.
ElectricityEngineering works in the field of electricity.
↳ Method
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.
