This project provides funds to rehabilitate and provide corrosion protection for four Air Floatation Tanks at the Water Pollution Control Plant (WPCP) which are steel and concrete structures. Air
floatation tanks are used to remove the algae that grows during secondary treatment in the oxidation ponds. Three of these structures were built in 1975 and the 4th one in 1982, and all are in need
of significant rehabilitation. This project includes repair/replacement of the steel and mechanical portion of this structure, repair and/or replacement of the influent gates and coating of the concrete
walls, extending their useful life for approximately 15-20 years. The cost analysis is based on an internal estimate and includes $730,000 for design and construction for each tank. Estimates will be
updated upon receiving competitive bids. Condition assessment of the tanks is complete. Design is currently underway with construction of the tanks scheduled one at a time beginning in FY
2009/10.
Project Evaluation and Analysis
The maintenance on these structures is critical to maintain process and regulatory compliance. This project will allow staff to take each of the tanks out of service, one at a time, and perform the
needed preventive maintenance.
Fiscal Impact
This project is funded by transfers form the Wastewater Management Fund.
