A portable cofferdam system for isolating a working area from water such as a culvert. The portable cofferdam system generally includes a first sidewall and a second sidewall each having an interior side, an exterior side, an upper edge, a lower edge and a rear edge. A middle wall is connected to the sidewalls opposite of the rear edges of the sidewalls forming a substantially U-shaped structure. An opening formed between the rear edges of the first sidewall and the second sidewall to allow for positioning about or near the inlet of an object or area to be kept dry such as the inlet of a culvert.

A sump pump system includes a water intake port, a water accumulation reservoir, a water discharge pump, and a vacuum pump. The reservoir includes a first port, a second port connected to the water intake port and positioned above the first port, and a third port positioned above the second port. The water discharge pump is connected to the first port to empty the water accumulation reservoir. The vacuum pump is configured to decrease air pressure in the water accumulation reservoir below atmospheric pressure on a scheduled or timed basis. Low pressure forces the water to flow from the water intake port into the water accumulation reservoir. When no water is present, it causes active air ventilation in the vicinity of the water intake port, which improves a state of dryness and eliminates any small amounts of water that may still be present.

An underground water barrier installation system is provided herein, that contains a plowing apparatus having an enclosed chamber and a frame located above it. The system either has a roll of film located in the enclosed chamber beneath the ground, or alternatively, the frame contains a roll of biodegradable film and two rollers containing line above the ground. In the system having the roll of film located above the ground, the lines from the rollers are heat affixed to the edges of the film by two heated roller binding mechanisms. The system then also includes a cylindrical duct system which can efficiently move the film having the lined edges therethrough and into the internal chamber of the plowing apparatus, wherein the film having the lined edges is straightened by passing the lined edges through two side straightening mechanisms and then is fed through a slit in the back of the plowing apparatus. There are also provided methods herein which comprises providing the water barrier installation system, feeding the film, and if present, lines for the edging through the system; attaching the frame of the system to a towing vehicle and pulling the plowing apparatus at a depth through the ground such that the line edged film is dispensed at the depth in the ground behind the plowing apparatus as it is pulled through the ground.
