Standard Colors

SunShield Colors

Why does color matter?

Water Storage TanksOur standard tanks include built-in UV inhibitors to avoid color fading and breakdown from harsh sunlight, available in 13 different colors. Although Black and Dark Green limit the most light from entering standard tanks to prevent algae growth, we offer a premier line of SunShield® tanks boasting zero light penetration in 11 additional colors, including Arctic White.

For more information about the impact of properly shielded tanks, read the Texas A&M AgriLife Research Center's study: Effectiveness of Poly-Mart SunShield® Colored Tanks Relative to Water Temperature and Light Infiltration.

Why would I need a water storage tank?

Larger water storage tanks are often used as part of well water systems. They can hold thousands more gallons than typical pressure tanks and extend the life of your underground pump, saving it from the wear of cycling off and on too frequently.

The extra water capacity also means that you can make use of water in your household for multiple purposes at once without seeing a drop in pressure, so someone can take a shower without having to interrupt the clothes washer. If the storage tank is elevated above your home or other intended destination, it can use gravity to continue to provide water even during a power outage.

But as the name implies, any situation that needs water stored is a good one, which could be permanent installations around the home or just taking a few hundred gallons out on an extended camping trip.

Some more applications for Water Storage Tanks include:
  • Properties with low gallon-per-minute output
  • Venting sulfuric gases from water before they reach faucet
  • Irrigation systems
  • Filling troughs for livestock
*All Tanks of all colors are BPA-Free and manufactured with resin that complies with U.S. Food and Drug Administration regulation 21CFR 177.1520 (1) 3.1 and 3.2 for storage of potable water.
