Photos: Massive Tucson Water storage cell gets rehabbed
30-million gallon water-storage cells at Tucson Water's Clearwell Reservoir are being refurbished.
Rolando Palacio grinds the surface near the access stairs to prep the area for the liner as work continues on the rehabilitation of the Clearwell Reservoir in the Tucson Mountains. The roof was removed and will be replaced on the facility. The reservoir is Tucson Water's largest potable water storage facility. It consists of two equal sized cells, both holding 30 million gallons each that were built around 1993-1994, said Dorothy Dolan with Tucson Water. They are only working on one cell at this time. In addition to reinforcing the facility by upgrading the supports to the roof they are replacing the base with 207,000 square feet of a synthetic rubber liner, Dolan said. After all rehabilitation and inspections are complete they expect to be back in service by late April to early May, Dolan said.
