Reservoir Cover Solutions

    CST has been providing custom engineered all-aluminum water reservoir cover solutions in the potable water market for more than 55 years.  Large water basins and reservoirs are a particularly difficult challenge. The water must be covered effectively to meet surface water regulations. At CST, our aluminum specialty covers have been designed to cover some of the largest water reservoirs in the world.  

    CST has a unique “strut and panel” system that can accommodate virtually any reservoir shape or size. The all-aluminum design employs geodesic dome engineering principles for a lightweight cover as clear-span, truss supported, or internally supported by columns. 

    New or Retrofit

    CST’s cover systems are ideal for both new construction or retrofit projects and require little modification of the existing tank.

    Perhaps most importantly, CST all-aluminum covers are inherently corrosion resistant and offer strength and durability unmatched by steel, wood, concrete, plastic or other alternatives. CST aluminum cover systems provide maintenance-free, long-lasting (minimum 50-year design life), secure, and environmentally friendly fixed cover solutions to protect valuable potable water.  


    An open body of water is vulnerable to all types of contamination. Surface water runoff, bird and animal wastes, human activity, algal growth, and airborne debris can be hazardous to all bodies of water, but uncovered reservoirs used to store finished drinking water are especially vulnerable to contamination. CST (formerly Temcor and Conservatek®) designs innovative clear-span aluminum reservoir tank covers for water storage tanks of all sizes that prevent water intrusion.

    In addition to low maintenance, low cost, and low profile advantages, CST’s aluminum covers are versatile enough to permit a wide range of accessories important to the water industry. CST has designed, fabricated and installed over 20,000 covers worldwide.
