ABSTRACT:
Portable, self-powered water pumping apparatus for use in sampling water in remotely located wells comprises a wheeled hose reel cart which supports a long length of co-extruded plastic hose or tubing. The co-extrusion comprises a small diameter portion of tubing attached by a web to a large diameter portion of tubing. The smaller diameter tubing is connected to a pressurized cylinder of gas such as a standard 14 oz. propane gas cylinder. A generally J-shaped piece of metal tubing projects from the inside of the smaller tubing, which it frictionally engages, into the center of the larger tubing at the lower end thereof. When the lower ends of the tubes are well submerged beneath the water level in a well, admission of gas to the smaller tube at its upper end will force water which enters the larger tubing in the annular space surrounding the metal tubing up through the larger tube and out the upper end of the larger tube so that it can be collected. To facilitate the insertion of the extruded tubing into a well from the coil in which it is stored, the tubing is formed of a plastic such as a vinyl and acetate modified polyethylene which has a memory and which is flexible at low temperatures. Preferably, the tubing is permitted to lay straight for several days following extrusion. A weight is also hung from the lower end of the plastic tubing to facilitate its entry into a well.
