Responding to an increasing population base, soaring water prices and dwindling private
groundwater supplies, Rockdale County, Georgia, undertook a $68 million capital improvements program
to produce and distribute its own potable water. But the time frame for critical water pipeline
construction was a mere 11 months. The improvements included nearly 20 miles of large
diameter water transmission mains and a raw-water intake. Five major river crossings occur in
the program, one at the raw-water intake, another on the raw-water transmission main, and three
on the finished-water transmission mains. Pipe diameters crossing the river are 36-inch and 42-
inch. This is a comparison of the river crossing methods employed by each of three contractors in
their efforts to race across the river in an expedient, economical, and environmentally friendly
manner. Each contractor experienced difficult conditions, uncooperative weather, and heavy
scrutiny by environmental authorities. And each contractor in a competitive spirit was convinced
that his methods for controlling schedule, river infiltration, erosion and sediment release were the
best for accomplishing the work. Includes table, figure.
