A flood control system for remotely and automatically controlling flooding and water storage on reservoirs. The flood control system generally includes a central computer that controls the water level by controlling or communicating with flow control gates positioned near a number of culverts, wherein each flow control gate typically includes: (a) a control unit communicatively coupled to the central computer, the control unit capable of sending local condition data to the central computer via a wireless connection and further capable of receiving control commands from the central computer; (b) an input/output interface capable of receiving signals or data regarding physical conditions proximate the flow control gate, the input/output interface coupled to the control unit; and (c) a water shutoff valve controllable by the control unit and positioned to selectively allow or block the flow of water through each culvert, wherein each control unit controls each water shutoff valve.

A system for stopping flow in a pipe with a plug positioned in the pipe to allow for repairs of the pipe. The plug comprises a body with an inflatable or compressible member, and a cap and connector valve on the body. An inflation line with a coupling connects to the valve for blocking off and sealing a damaged area of the pipe. An inflation line is used to deposit and retrieve the plug within the pipe before and after a repair is made.

A passive sequential pump system for use in moving a fluid is provided. The system comprises a plurality of valves. Each valve of the plurality of valves is positioned adjacent to another valve of the plurality of valves. Each of the plurality of valves includes an opening and an inner surface. The inner surface is expandable towards the opening. The system also comprises a conduit defined by the opening of each of the plurality of valves. The system further comprises an air source providing air to each of the plurality of valves and a controller controlling the air source to each of the plurality of valves. The system generates peristaltic motion to move a fluid through the conduit by increasing the air in each of the plurality of valves, thereby correspondingly closing each opening in sequence, peristaltic motion is generated to move a fluid through the conduit.
