Yes, our above ground tanks and below ground cistern tanks are made from 100% virgin, food grade polyethylene resin that is material the FDA has approved as safe for potable water use. Keep in mind, when you’re storing potable water in a poly tank, it’s important to keep all the light out of your tank to prevent mold build up. Make sure you choose a tank with a lid that seals so it’s easy for you to keep it closed and your water in drinkable condition.
Good question. Make sure to pay attention to the specific gravity listed in your tank’s product description. Tanks that are listed as having 1.5-1.6 specific gravity are considered premium tanks and can hold liquids weighing up to 12.5 pounds per gallon. Heavy duty tanks with a specific gravity of 1.9 or higher can handle liquids weighing up to 15.8 pounds per gallon. Please note: If you store liquid chemicals that require a specific gravity higher than the tanks maximum capacity will void the warranty.
Polyethylene tanks can withstand temperatures up to 120 degrees Fahrenheit. However, they don’t have a minimum temperature rating. Storing liquids in your tank above this temperature can permanently weaken your tank. Keep in mind, liquids with low flash points cannot be stored in poly tanks. This is because of the 120 degrees F maximum allowable temperature in these tanks.
Even though there are a variety of chemicals you can store in your poly tank, since there are a vast amount of different chemical concentrates, we strongly encourage you to contact our expert salesperson to ensure the chemical you want to store is compatible with your tank.
The only tanks that can be buried are cistern and septic tanks. This is because they have ribbed walls that gives them structural integrity and will not collapse from the backfill procedure. Be aware, each state has its own legal regulations for installing septic tanks and it’s your responsibility to make sure you’re following the laws of your area for using this type of tank.
It is recommended that you properly install a concrete pad for any vertical tanks over 2,000 gallons.
