Description
1500 Gallon Underground Propane Tank
Step up beyond the standard 1000 gallon and into the 1500 gallon class with this underground propane tank built for properties with serious propane demands. Buried out of sight, it provides 50% more storage than a 1000 gallon while costing far less than two separate tanks.

- 1500 gallon water capacity — approximately 1,200 gallons usable propane
- Designed and certified for permanent underground installation
- Steel construction with factory-applied corrosion-resistant coating
- Dome assembly with standard valves, gauge, and relief device
- Engineered for soil loading and hydrostatic conditions
- Compatible with cathodic protection via magnesium anode bags
- Ideal for properties that have outgrown a 1000 gallon tank
Who Needs 1500 Gallons?
This underground propane tank serves large homes over 4,000 square feet, multi-building farm complexes, commercial properties with substantial heating loads, and anyone who wants to fill up less frequently. With 1,200 gallons of usable propane, you may only need one or two deliveries per year depending on your consumption. That infrequency also means you can time purchases for the lowest seasonal propane prices.
Underground Advantages
A below ground propane tank of this size would dominate a yard if installed above ground. Going underground makes the tank invisible, protects it from weather and physical damage, and often allows more flexible placement since buried tanks have different setback requirements. For properties where appearance matters — and where space for large above ground equipment is limited — underground is the clear winner.
Installation Considerations
A 1500 gallon underground propane tank installation requires professional excavation equipment, proper sand bedding, cathodic protection anodes, approved backfill material, and a licensed propane installer. Plan ahead and coordinate with your installer for a smooth process.
