Client: Altoona Water Authority
Year Completed: 2003
Project Cost: $3,750,000
Oakton Reservoir, a 1915-erra concrete water distribution reservoir, showed significant deterioration and leakage. Seeking a permanent storage solution, the Altoona Water Authority authorized Gwin, Dobson & Foreman, Inc. to engineer a unique, but cost-effective water storage tank.
The project included the following elements:
- Design of two (2) 3.24 million gallon water storage tanks, consisting of AWWA D110-95 Type III wire wound circular prestressed concrete
- Tanks incorporated unique tank mixing piping system to promote tank mixing and turnover
- Design of “super high” water booster pumping station including two (2) five-stage vertical turbine pumps rated at 500 GPM and 235 feet TDH
- Demolition work for existing concrete open reservoir and hypalon liner/cover system
- Extensive site work and design including site excavation, access roads, landscaping and fencing
- Site storm water drainage system and 20-inch water transmission main connections
- Extensive subsurface investigations, soil/rock testing and foundation design
- Coordination of neighborhood meetings and public participation including handout materials and 3-D model presentations
The project was deemed a complete success by the Altoona Water Authority. Funded by a low interest loan from the PA Infrastructure Investment Authority, the project was completed on-time and under budget.
