Résumé


Abstract:
Through the bibliography, it was noticed that the dimensioning of the collectors of cleansing
(unified or separative); generally, disregarded intrusion of parasitic water. This intrusion is
dependent on the characteristics of the ground, the groundwater and the state of the collectors.
These parasitic waters are often residing in the center of the problems which daily worry the
managers of the systems of cleansing, and more particularly the stations of- purification. The
random quantitative aspect of this water often modifies the characteristics of the flows and often
obliges the researchers to re-examine the simplifying assumptions of the mechanist models
governing the flows in the collectors. In this context, our work consists initially to present the
causes and origins of this water and to propose thereafter a mathematical approach of
quantitative determination of the flow of intrusion.
