Deer Valley Water Treatment Plant

The scope of work included demolition of the existing hopper bottom, metal roofed reservoir, the construction of a new 20 MG cast-in-place reservoir, installation of chemical feed piping, level sensors, transmitters and associated conduits and control wiring.

Project construction occurred during active plant operations with some activities needing close coordination with both security personnel and plant operations staff. Kiewit provided the City and the Engineer full preconstruction services including cost models, constructability reviews and scheduling analysis throughout the design. The project included:

• Demolishing existing reservoir structure and replacing with a new 20 MG concrete cast-in-place reservoir with major structural components having an expected life-span of 60 years or more.
• New reservoir included all present process control and security features.
• New reservoir included baffle system to ensure CT disinfection.
• Modifications to inlet/outlet piping of new reservoir were required.
• Chlorine system upgrades.
• Minor site improvements associated with the new reservoir such as drainage control and site lighting were included.
