"The only derivation mill attested by old documents and moreover still visible in the entity of Soignies is the CARLON mill (Thieusies, on the Obrecheuil). It is located downstream of the Roquettes mill, almost at the limit of the territory of the former commune of Saint-Denis. The development of a mill of the type of the Carlon mill required, upstream, the creation of a reach of water supply and, downstream, of another reach for the return of water to the normal courtyard and the primitive bed of the river. He also called for the establishment of an adjustable water intake system for the regular and safe supply of the reach. a dam was established with an overflow ensuring a constant constant level in the reach and taking from the river the right amount of water necessary (no more, no less) for the operation of the mill. Thus appears, in the bottom of the valley of the Obrecheuil, a double course for the river: "true river" on the one hand, barred by a valve flooding the reach; "false river" (or reach) of the other, with zero slope (or almost zero) gradually moving away from the original course, notching, if necessary, the slope of the valley and ending at the mill.
