A catch basin is provided for insertion into a pre-existing storm drain connected to a storm drain system, the storm drain having a shoulder around its upper periphery for supporting a pre-existing, perforated storm drain cover. The catch basin selectively controls the flow of liquids and viscous materials into the storm drain system, and includes a flexible, fluid impermeable container extendable into the storm drain with its edges extendable over the storm drain shoulder about the periphery thereof. The flexible, fluid impermeable container includes a drain hole providing an outlet to the storm drain system. A rigid valve member is attached to the flexible, fluid impermeable container and is configured to selectively open and close the drain hole. The rigid valve member includes a vertically extending wall surrounding the drain hole and extending upward therefrom a distance h to define an opening. With the drain hole open, liquid accumulating in the flexible, fluid impermeable container will not pass through the drain hole until the liquid rises to a level exceeding the height h of the vertically extending walls surrounding the drain hole. The catch basin further includes a plurality of vertically extending leg members attached to the rigid valve member, with each of the plurality of vertically extending leg members having a horizontally extending flange engagable the storm drain shoulder on top of the flexible, fluid impermeable container to maintain the catch basin within the storm drain.
