Propane Tank Ownership
Superior Energy is a full-service propane company. It’s our goal to be the most reliable, safest, and responsive propane company in the region. Our technicians are expertly trained on propane safety and frequently check your system to ensure that it meets safety requirements. They perform the following:
- Visual tank inspection at time of delivery
- Swap out and/or painting of the tank as needed
- Labor to repair and/or replace regulator as needed
Customers using Superior Energy-owned equipment will be assessed a Tank Usage and Maintenance Fee (sometimes called a tank rental fee) during the period that the equipment is used. The amount can vary depending on, among other things, the size of the tank, the location of the residence, whether it is an above or underground tank, and your actual annual usage. As owner of the tank(s), we are responsible for any needed maintenance and compliance with all applicable safety regulations. We pay close attention to required service and maintenance of the tanks and regulators for the protection of our customers. If the tank ever needs repair or replacement, we do that with no additional charge.
You are always welcome to purchase the tank, please contact our office to get current pricing. Customers who own their own tanks are responsible for the upkeep and protection of the container. See the industry recommendations for your tank:
We offer underground tanks from 300 to 1000 gallons for an excellent, low profile storage solution. These tanks are environmentally friendly, constructed of heavy steel and are specially painted with a mastic coating to prevent corrosion. They increase curb appeal because only the tank dome stays above ground; it houses the regulator, gauges and filling port. A small amount of excavation is required.
Underground tank requirements
The separating distance between a private well water supply system and an underground propane storage tank system is as follows:
- If propane tank has a water capacity of less than 2000 gallons = 25 feet
- If propane tank has a water capacity of greater than 2000 gallons = 50 feet
In addition, propane system should be at least 10 feet from septic system/leach fields.
Note: a propane storage tank system includes the storage tank, piping and other equipment associated with storage, or the transfer of the propane from storage.
For trench: Underground line to the tank must be 18 inches below ground level (with a 4-6 inch sand base) or 24 inches below ground level if it is to be driven over (such as under a driveway, etc.)
