Arguably, the largest conglomerate steel
mill in the country needed to replace an aging Waste Water
storage tank. The 40,000 gallon tank was over 25 years old, and
an old “Cab-O-Wrap” design, consisting of cables supporting thin
panels of pre-fabricated fiberglass (FRP). These tanks were
used extensively in the 60’s and 70’s, but are no longer
available or specified.
provide the capacity required and utilize the existing
“footprint”, CRECO quoted a self-supporting tank that is
pre-fabricated at the factory in sections and then assembled in
the field. Because the tank is too large a diameter to ship
over the road, the bottom and top are sectionalized and the
shell sections are “OBLATED” to allow conventional shipping .
On the site, the sidewall sections are “PROLATED” back to their
original diameter and fiberglass “welded” together. Likewise,
the top and bottom pieces are fiberglass welded and the whole
tank is joined as one unit. Lastly, fittings, manways, and
accessory attachments are field located and glassed into place.
This tank was erected in 5 days with a
crew of 4 men in March, when it’s still rather cold in NW
Available in standard diameters of 16’,
20’, 25’, and 30’, and in heights as needed, size doesn’t matter
