Abstract

Water treatment plant having pretreatment means, such as in particular means of desanding, degreasing, physico-chemical pretreatment such as coagulation and flocculation and biological pretreatment, as well as means of separating the solid particles contained in the untreated water, characterized in that the solid/liquid separation means are contained within a construction of circular shape, and the untreated-water supply means as well as at least one of the pretreatment means are incorporated in a structure in the shape of an isosceles trapezoid whose projected apex lies on a diametral axis of the construction of circular shape containing the separation means, whose sides are formed by the two tangents to the circular construction leading from the said projected apex and whose base is tangent to the circular construction at the point of intersection of this construction with the diametral axis.
