Trenchless construction techniques were used to cross major highways, railroads, utility lines, drainages, canals, creeks, irrigation ditches, wetlands and the South Platte River. MWH experts navigated significant subsurface variations including claystone, siltstone, sandstone, clay and alluvial sands and gravels. Due to high groundwater conditions, significant dewatering was required at trenchless crossings and along much of the overall pipeline.
The conveyance system includes three 6,000 horsepower pumping stations and has a capacity of more than 21,000 cubic feet.
MWH engineers performed hydraulic and surge analyses and design for system protection from both controlled and uncontrolled shutdowns.
As part of this project, MWH implemented ActiveManualsTM as an electronic operation and maintenance manual for the four divisions of the City’s water operations group. The manual provides Aurora Water with a system-wide, database-driven electronic solution that is user-friendly and easily updated.
The project’s primary facilities are complete and were placed into operation in October 2010.
