Powell Butte & Kelly Butte Reservoir

Special Inspection
Through a contract with the City of Portland Bureau of Environmental Services, NTI is providing special inspectors to both the Powell Butte and Kelly Butte Reservoir projects. The City of Portland must have sufficient drinking water storage capacity to meet the anticipated growth in demand for water consumption and fighting fires. The city must also offset the loss of its five open reservoirs that, due to federal regulations, are scheduled to be disconnected by 2020. The $138 million project consists of a new 50 million gallon underground reservoir, an emergency overflow structure, a caretaker residence, and a maintenance building. The $90 million Kelly Butte Reservoir project includes a new 25 million gallon underground reservoir, access roads, overflow basin, and an intricate network of underground piping, vaults, and valve structures. NTI’s duties have included special inspection of reinforced concrete, structural masonry, structural steel, proprietary anchors, and structural wood.
