South Transmission System Parallel Line Project
Benton Washington Regional PWA
In order to meet the increasing water demands of the residents of southern Washington County, the BWRPWA needed to increase its transmission system capacity in that area. The existing 18-inch transmission line that delivers water from Benton County to Washington County was at its capacity. The BWRPWA chose to construct a 24-inch water transmission line parallel to the existing 18-inch line to increase the available capacity.
Contract 1 consisted of 6.43 miles of 24-inch ductile iron water transmission line from Gallatin Fire Department to Booster Pump Station #2. This includes air release valves, fire hydrant assemblies, gate valves, a testing station at the Illinois River, one creek bore and one Arkansas highway bore and one US highway bore-all with 36-inch steel encasement pipe and one cross connection with the existing 18″ water line.
Contract 2 consisted of 4.9 miles of 24-inch ductile iron water transmission line from Booster Pump Station #2 to the Lincoln Tank Site. This included air release valves, fire hydrant assemblies, gate valves, two creek bores and one Arkansas highway bore-all with 36-inch steel encasement pipe and one cross connection.
Contract 3 consisted of the addition of two vertical turbine can pumps to Booster Pump Station #2. This included the installation of the necessary process piping, instrumentation and controls, and a diesel fueled generator set to replace the existing generator.
Contract 4 consisted of the Illinois River horizontal directional drill.
