152. For a given loading rate, a hydrodynamic separator may be installed in a parallel configuration if a test for resuspension of sediments conducted at a loading rate corresponding to at least 125% of the given loading rate has been successful.
An installation in a parallel configuration is an installation in which flows equal to or less than the treatment capacity of the hydrodynamic separator are sent, the excess flows being bypassed upstream by an outside work to bypass the hydrodynamic separator in order to reach the storm water management system downstream of the hydrodynamic separator.
