Waterspheroid® Elevated Tanks

CB&I Storage Solutions developed the Waterspheroid in 1954 as a larger-capacity alternative to our original Watersphere tank. Today, the Waterspheroid is our most popular style of elevated water storage tank for capacities up to 1,000,000 gallons, providing reliable service to thousands of municipalities and industries. 

Waterspheroids are available with storage capacities of 150,000 to 2,000,000 gallons. The sleek design has low capital maintenance costs and a small footprint that requires minimal land use.

We provide complete engineering, procurement, fabrication and construction services for Waterspheroid tank projects. We utilize our own in-house resources to perform tank and foundation design, fabrication, construction and painting. This comprehensive approach helps us minimize costs, adhere to project schedules, control quality and reduce the customer's risk. 

Offering a Variety of Tank Features

Standard features for our Waterspheroid tanks include flush threshold steel doors with deadbolt locks to prevent unauthorized entry, and interior ladders to facilitate access during inclement weather. The tank bell or pedestal provides space for storage or as housing for telecommunications equipment, pumps, valves, piping and controls.

We offer a number of optional features, including decorative graphics and logos, cathodic and lightning protection, overhead doors, double personnel doors, stainless steel risers and overflows, tank drains, FAA lighting, intermediate platforms, instrumentation and telemetry.
