ABSTRACT The device relies on two manifolds. One divides the water flow into several smaller diameter hoses that lay parallel on the ground surface. Theother collects the water from the smaller diameter hoses. These manifolds are constructed from material which withstands both internal water pressure and the external force of a heavy vehicle inadvertently crossing over it. Water flow would not be compromised while in these manifolds. The small diameter high pressure hoses have a total sum flow capacity greater than the input/output connections. A greater friction loss is experienced with smaller diameter hoses and with vehicles compressing some hoses when crossing over. This flow reduction is eliminated by adding more small diameter hoses. A centre manifold that would allow an additional lane of traffic to cross over, could be added. This centre manifold redirects water flow to all hoses on opposite side. This means compression of hoses on one side does not have water restriction to any hose on the opposite side. Protective coverings can also be added to protect hoses from the ground and damage caused by vehicle braking. The manifolds would have small water vents that would produce a spray. The top covers would have a surface that, when sprayed by water from the manifold vents, would produce a somewhat slippery surface. This would still allow vehicles to brake safely on the top cover without causing damage to the smaller diameter high pressure hoses.
