Statutory Approval & Engineering Endorsement
Under national environmental regulations issued by the Ministry of Environment, Urbanisation and Climate Change, constructing or upgrading any domestic, industrial, or municipal wastewater treatment plant requires an official Project Approval Dossier sanctioned by competent authorities prior to ground-breaking.
DES ÇEVRE delivers turnkey engineering dossiers—from influent characterization to reaction kinetics, hydraulic elevations, and civil/mechanical/P&ID AutoCAD deliverables—handling institutional liaison until final ministerial sign-off is achieved.
Our 3 Project Approval Dossier Services
Engineered to meet 100% of ministerial technical guidelines across domestic, industrial, and municipal infrastructures:
1- Domestic Wastewater Treatment System Project Approval Dossier
Statutory approval documentation for package biological treatment and compact MBR systems located beyond municipal sewerage connection grids.
