摘要
A shortage of good quality livestock and household water has plagued northwest Nebraska ranchers. The development of Polyvinyl-chloride pipe has provided a method of piping good water into this area. Five hundred forty five miles of PVC pipe have been installed, or are planned, on 108 ranches watering approximately 300,000 acres of rangeland. This productive grassland area can now be grazed safely and efficiently with a stable, good quality water supply.
