Reed Reservoir Project

Awards: 
2012 Honor Award (Project of the Year Runner Up) for Utility Projects under $6 million - American Public Works Association (APWA)
Service Type: 
Project Highlights: 
  • Maintained the function of the existing water system by matching the existing reservoir maximum water elevation.
  • Provided one reservoir structure with two internal basins for operational flexibility.
  • Demolished the existing steel tank after completion of the new reservoir.
  • Seismic considerations included that the reservoir be designed for hydrodynamic forces taking into effect the sloshing of the stored water inside the reservoir during an earthquake and the resultant forces exerted on the reservoir walls.
Reed Reservoir
Matching the high water and floor elevations of the existing tank sets the most important criteria for dimensioning of the new 5-MG reservoir.

Carollo is designing a new 5 million gallon concrete tank reservoir to replace an existing steel tank that has reached the end of its useful life. The design includes a complex slope stability and foundation design to accommodate a challenging site. The reservoir configuration options (circular versus rectangular) were evaluated based on the unique site characteristics and the need to fit into the overall existing water distribution system. The new reservoir will match hydraulic elevations dictated by the existing system and minimize the pipe lengths needed to tie the new tank into the existing pipe network. Our design included consideration for site access, site security, pipe overflow and drain piping, as well as changes to the current SCADA system.
