Updating of the database and the establishment of the new necessary data for the study.
Identification and diagnosis of the existing networks as well as the possible refusals (dis-charges).
Study and hydrological modeling of the inflows from the basins outside and inside the study area and calculation of the flows to drain.
Ground layout and alignment of primary and secondary stormwater networks (pipes and lift stations): different variants are studied and compared from a technical and financial point of view and then submitted to the client for advice.
Modeling and simulation of the operation of existing and projected systems using the Epa SWMM software.
Preparation of the preliminary project file on the basis of the variant selected by the client and whose components were the subject of a topographic survey.
