Things You Need to Consider in an Underground Tank Installation


There are a few things that you need to consider when constructing an underground tank. First, determine what material you want to use as backfill. Backfill material must be able to compact and flow, free of rock and sharp objects. Also, you need to consider what kind of tank you’ll use in an underground tank installation Westchester County, NY

Metal tanks

There are many things you need to consider in an underground tank install. First, it is imperative to ensure the tank will be leveled and protected from collapsing. The backfill material must be compact and flowable. The soil should also be free from sharp objects. By reading the manufacturer’s instructions, ensure that the backfill material is a good fit for the tank. It would help if you leveled the tank before removing the straps and mounting them to the ground.

The next step is to install the risers. If you choose a buried tank, you should make sure that there are adequate ventilation holes. Most tanks are designed to contain wastewater and must be vented to prevent sewage overflow. Make sure you have the proper pipe ties. Afterward, connect the risers to the top of the tank using the gasket and lid provided.

Fiberglass tanks

While the cost of fiberglass tanks is higher than steel tanks, they are highly durable and will not break down. As a result, these tanks are preferred by fuel marketers in humid and dry climates. The material used to build fiberglass tanks is oblong, which requires more space to be buried underground. On the other hand, steel tanks are flat at the ends, so they fit into underground spaces much more ergonomically. It would help if you also considered the installation cost when choosing. If you plan to install a fiberglass tank underground, it’s best to hire a professional to complete the project. You can save money if you opt for steel tanks.

Propane tanks

The first thing you need to know about underground propane tanks is that they are exposed to various conditions and elements. Therefore, it’s important to protect the tank from corrosion. Gravel can cut through protective coatings, and gravel can result in a leak that is not readily apparent. It has caused injuries and property damage in many cases. To prevent such problems, it’s best to protect underground tanks from electrolysis by using an anode bag.

Copper pipes

Among the benefits of copper piping is its corrosion resistance. The material is also more dependable than PEX, a more flexible plastic alternative that can crack easily. Although copper is 60 percent more expensive than PEX, this material is a better choice for underground tank installations since it can last up to 70 years. Copper pipes can also crack when exposed to freezing temperatures, so installation should take care of. However, the material is widely used in underground tank installations for various applications.

The proper installation of copper underground pipe requires moling. It is also critical to consider soil corrosivity and other conditions. In questionable soil conditions, it is essential to test the corrosivity of the area before proceeding with the installation. The soil should be compacted after the excavation to ensure no sharp objects are nearby. Qualified professionals should perform copper pipe installation. Once installed, it should be waterproof.


If you plan to install an underground tank on your property, you should know the regulations before starting. First, the tank should be placed on firm foundations and covered with non-corrosive materials, at least six inches thick. When setting the tank, avoid dropping it because it can damage or puncture its protective coating. Also, you should ensure that the tank’s area is at least two feet wide. Then, cover the tank with soil.

Under federal rules, a company must register its underground tank with the DEC. The regulations govern underground storage tanks’ construction, operation, and maintenance. They also require the company to have financial responsibility for any corrective actions if a leak occurs. 


The cost of underground tank installation varies, and some factors are more important than others. First, the location of your home can influence the price. A yard with a steep incline or rocky terrain will increase the installation cost. If your home is far from a tank company, you should expect the cost of piping to be more. Additionally, if the soil is spongy, it will increase the installation cost.

The price of underground tank installation can start at $1,000. This cost includes digging the ground to install the tank and trenching a gas line, which costs approximately $75 to $800. Then, the installers lower the underground tank into place and connect it to the gas line. The tank is then filled in with soil and grass seed. Therefore, the cost of underground tank installation can go up to $1,000 depending on the type of soil and the location.
