Within the past 11 months, crews prepared the butte for the new 25-million-gallon underground reinforced concrete reservoir, a temporary haul road, an intricate network of underground piping, multiple vaults and an overflow basin.
Over the summer, the site continued to be excavated to ensure ample room for the two individual cells that will comprise the 25-million-gallon reservoir.
Inlet and outlet pipes that will run under the reservoir have been placed and will soon be encased in concrete to provide seismic stability and support for the pipes.
The floor slabs for the Parkrose (South) meter vault, North valve vault and the Conduit 3 meter vault foundation have been poured and the exterior wall construction for each structure is in process.
Within the next six months, the construction site will look significantly different. The 25-million gallon reservoir will begin to take shape with multiple concrete slab pours and wall and interior column construction. Pipes will be encased in concrete and buried, and the concrete vaults will be fully constructed.
In the winter of 2013-14, crews will tie-in Conduit 3 at SE Powell Boulevard. Conduit 3 - installed and placed online in 1925 - will deliver water directly from the Bull Run Reservoir 2 to Kelly Butte Reservoir. Kelly Butte is projected to become operational in the winter of 2014 with the entire project slated for completion in summer 2015.
