HydroTec®

HydroTec® Liquid Storage tanks are the industry standard for epoxy coated bolted and factory welded storage solutions.

HydroTec - Marble Hill Reservoirs

HydroTec TS storage tanks incorporate horizontally-oriented panels, mastic sealer and 4-corner joint designs.

 

If it's water, wastewater or industrial liquids, we've got it covered.

CST's HydroTec® storage tank systems (formerly Columbian TecTank®) are the comprehensive storage solution for any fluid and are recognized as the industry standard storage solution specified by the largest engineering firms in the world. HydroTec systems offer experienced, fast and economical construction with a proven track record of storage success. With 250,000 tanks in 125 countries performing in thousands of applications, no other company can match CST's design, manufacturing and construction experience.

HydroTec Storage Tank Systems: High quality at the lowest cost per gallon

  • Low installed up-front costs
  • Longer tank life = lower life cycle costs = quicker ROI
  • Fast tank construction save you time and money
  • HydroTec tank systems are the "Green" choice in liquid storage

HydroTec Designs

The performance and quality of HydroTec storage tanks are available in three primary designs. All are manufactured under the strictest of quality process controls in ISO 9001:2008 certified facilities, all are designed using the latest engineering tools and all are supported by CST's seasoned project management teams.

Hydrotec TS

HydroTec TS  

HydroTec TS storage tanks incorporate horizontally-oriented panels, mastic sealer and 4-corner joint designs. The tanks are built top down using construction process using jacks so that construction does not require high scaffolding and the tanks are easily expandable.


Hydrotec CS  

HydroTec CS  

HydroTec CS storage tanks are constructed with vertical panels and use gaskets. The tanks are generally scaffold built so they do not require any special jacks to construct. The chime joints add additional stiffness to the tank's structure.


Hydrotec Welded  

HydroTec Welded  

HydroTec Welded storage tanks are generally one-piece welded construction although tanks larger than 80 ft (m) are available in multi-piece designs. These ready-built tanks minimize costly on-site construction time and can be pre-fitted with customer supplied equipment.
