  When it comes to protecting the integrity and quality of your potable water supply, customers trust CST. CST’s Aquastore tanks with Vitrium™ glass-fused-to-steel (enamel) coating offer the lowest total life cycle costs because the glass coating on the tank panels is never recoated during the entire tank’s life. CST’s HydroTec (formerly Columbian TecTank) tanks offer the durability of factory-coated and cured epoxy coatings using our proprietary OptiBond™ process at a low upfront cost. Both coating options are NSF approved. CST also offers galvanized tanks including VULCAN Tanks with and without liners for one of the most upfront affordable water storage options. CST’s Temcor and Conservatek domes and reservoir covers offer custom designs to fit any size and shape tank or reservoir while offering the unmatched low-maintenance and ease of assembly of aluminum.  
     
  Aquastore  
     
  Aquastore glass-fused-to-steel tanks are the most recommended water tank in rural water districts where overall cost, dependability and water quality are important attributes of water storage tanks. Larger tanks for urban use are also popular.  
       
 

 
     
 

 
       
  HydroTec  
       
  Hydrotec factory-coated epoxy tanks are the premier epoxy tanks for municipal and industrial water applications where quality is important but upfront cost plays a more important factor in tank section.  
     
  Vulcan Galvanized  
       
  CST’s Vulcan™ and galvanized bolted tanks fill an important niche in the overall water storage tank selection portfolio providing very low upfront cost options when long term durability and environmental degradation are less important factors.

  Reservoir Covers  
       
  While CST's storage tanks are an excellent choice for above ground potable water storage, some operations and geographies dictate the use of reservoirs. In these applications CST's superior cover options are available to safeguard reservoirs reliably and economically. CST's aluminum structures can span large areas using supported and unsupported designs. Covers can be constructed in round, none-circular shapes as well as custom configurations.  
       
 

 
       
  Detailed engineering and precision manufacturing make the assembly of these covers fast and easy. The result is a solution our customer's can rely on for many years of protection. The high strength aluminum alloy components and aluminum and stainless steel hardware make CST's reservoir covers virtually maintenance free. No rusting or repainting over the years makes CST's covers have the lowest total life cycle costs.  
       
  Steel Covers and Roofs  
       
  CST’s coated steel and glass-fused-to-steel tank covers offer alternatives to aluminum domes for smaller diameter tanks.
