Why a CB&I Hydropillar Elevated Tank?
Combining the support strength and multi-purpose inside
space provided by a large diameter support pillar, the
Hydropillar elevated tank is one o the most popular and
attractive styles o elevated water storage tanks.
CB&I invented the original Hydropillar tank design in 1962
and has been improving the concept ever since. We have
built more uted column elevated tanks than any other
company, including the tallest and largest capacity tanks
in service. CB&Is unique dome roo design eliminates
ponding, which improves paint durability and reduces
streaking on the side o the tank. The sel-supporting dome
roo also minimizes interior structural supports in the
vapor area o the tank where condensation occurs. Since
this is the most corrosion-prone area in the tank, uture
maintenance requirements are reduced.
The Hydropillar tank design ofers a high degree o
customization and exibility. The space inside the pillar
can be used in a wide variety o innovative ways, or it can
be reserved or uture expansion. Many sizes, options and
eatures are available or Hydropillar tanks, which provide
storage capacities ranging rom 200,000 gallons to more
than 4,000,000 gallons. In smaller capacities an optional
wineglass style ofers additional attractive and creative
applications.
Hydropillar tanks are all-steel, all-welded structures that
have proven reliability, serving municipalities and industries
or decades. The vertical steel utes accentuate the clean,
modern design. The large diameter steel pillar also ofers
excellent stifness to earthquake loads, superior suitability
or low load-bearing soil, and unobstructed access or
exterior inspection and maintenance. Properly maintained
and operated, steel tanks ofer an extremely long lie, with
some structures exceeding 100 years o service.
Since the construction o our frst elevated tank in
1894, CB&I has become a global leader in the design
and construction o elevated water storage tanks.
We pioneered the transition to welded steel tanks
in the 1930s and invented the original Hydropillar
tank in 1962. We also have been instrumental in the
development o the AWWA standards, beginning
with the frst D100 standard in 1941, continuing
today through active organization and committee
participation.On the cover: 2,000,000 gallon tank, Dublin, OH;STI/SPFA Tank o the Year
