A multiple inlet flow regulator with a restricted low-level inlet and upper-level overflow inlet is used to modify a new or existing storm water catch basin to regulate the flow of storm water from the catch basin into the sewer system. During periods of heavy rains and high flows into the catch basin, this flow regulator will allow the catch basin to serve as a temporary storage tank for storm water. The construction of these flow regulators can be accomplished using a variety of off-the-shelf components or custom fabrication, to achieve the desired effect of restricting the discharge from each catch basin in a combined sewer or storm water system as much as practicable without resulting in overflows onto the roadways. Key components include: restricted low level inlet that can be adapted in size to meet specific low flow conditions, upper level inlet sized to allow for the maximum discharge from the catch basin to prevent overflows onto the roadway, connections to the existing catch basin structure and covers to prevent floatable debris from discharging from the catch basin into the sewer system.
