Abstract

In Senegal, urban expansion and overpopulation, especially in the capital Dakar, have caused increased problems in terms of housing. To alleviate this scourge, the government of Senegal has decided to create new towns through the Diamniadio Urban Pole and that of Lac Rose to resolve the housing problem but also a set of economic activities. The ambition is to make these Clusters new urban centralities based on social and functional diversity, creating wealth and jobs. The objective of this article is to study the feasibility of the wastewater evacuation network and the treatment plant of the Diamniadio Urban Pole. The approach undertaken initially involves bibliographic research, followed by data collection from project stakeholders, then with the use of Excel software for determining flow rates, calculating and verifying the operating conditions. self-cleaning. Thus, we have achieved a wastewater treatment system with pipes whose sections vary from 250mm to 1000mm. For the operation of the STEP we obtained a pretreatment comprising a screen of 3 m² of surface, a desander of 4.5 m2 of surface, a degreaser of 190.71m² of surface, a primary decanter of 4768 m³ of volume, a treatment biological comprising an aeration basin of 101,002 m³ and a clarifier of 4,768 m³.
