This Item shall govern for the furnishing and fabrication of stainless steel flap gates. The flap gate shall be designed to allow free outflow and prevent backflow for maximum seating heads of 30 feet. This Item shall govern for the furnishing and fabrication of inline gates. The inline gate shall be designed to allow free outflow when internal pressure inside the gate exceeds the backpressure being applied on the gate. When the backpressure exceeds the internal pressure, the gate will close until the internal pressure inside the gate is again greater. Furnish labor, materials, and equipment necessary to provide a complete storm sewer system in conformance with the plans and specifications and in compliance with the Department's Utility Accommodations Policy (Title 43, T.A.C., Sections 21.31-21.55).
