ABSTRACT:
A storm drainage system including a gate which controls the release of the contents of the drainage system. The gate is motor activated which is responsive to manual activation or hydrocarbon sensor activation. The drainage system includes an overload sensor which detects a filled drainage system, for example by a heavy rain. The sensor provides a high-liquid-level override signal to the motor in response to the filled drainage system to open the gate independently of the hydrocarbon sensor activation.
