Water Or Fuel Tank Replacement Cost

Although some people replace water or fuel tanks because of wear and tear, others simply prefer a different type of tank. There are many types available including plastic, fiberglass, polyethylene, aluminum and steel. All home improvement projects come with a financial cost, and the price for replacing a water holding tank may vary from the price of replacing a fuel holding tank. 

Water Tank Cost

Generally, the replacement cost of a new water tank runs between $800 and $2,900. These amounts only apply to the labor involved in the replacement. Costs for the tank itself can be found in the table below.

Fuel Tank Cost

Above ground fuel holding tanks generally come with a capacity to hold either 275 or 330 gallons of fuel. These tanks are typically placed in a garage, shed or basement. Fuel holding tanks that are installed underground typically hold 550 or 1,000 gallons of fuel. Just like a water tank, removal of a fuel tank runs between $500 and $3,000, and installing a new tank may cost between $1,000 and $2,000, which includes the tank and the necessary labor.

Water Or Fuel Tank Replacement Cost Factors

Water Or Fuel Tank Replacement Cost Factors

Factors that influence the cost of water or fuel tank replacement include the size of the tank, whether the tank is above or below ground, the difficulty of the job and the specific contractor hired. Also important is the type of tank used. For instance, tanks with double-wall construction are more expensive than single-wall tanks, and steel tanks are more expensive than aluminum or fiberglass products.

Many consumers purchasing large tanks may need to also purchase a booster pump. This device increases pressure within the tank, which ensures quicker delivery of water, fuel or other liquids. Some tanks may also require protection from the sun, wind, rain, snow and temperature. Certain types of coatings that help prevent liquids from freezing and protect tanks from wear and tear may add to the cost of a new water or fuel tank.

Why Install A Water Storage Tank?

A water holding tank offers immediate access to water when needed. Water holding tanks benefit homeowners on city water or well water systems in cases of emergency. A holding tank for well water also helps in ordinary situations when water levels get low and need time for replenishment, and rural users benefit from water tanks in the event of brush or structure fires. In some rural settings, water storage tanks also help with irrigation.

Why Install A Fuel Storage Tank?

Fuel storage tanks offer a number of important uses like storage for oil to heat the home and/or storage for gasoline to keep cars and farm vehicles running. These types of tanks also store other kinds of liquids that mechanics, farmers or ranchers might need such as antifreeze, chemical solutions and/or hydraulic oil. Storing these liquids in large tanks saves time by reducing the frequency of purchase.

Water & Fuel Tank Considerations

Water & Fuel Tank Considerations

When purchasing a water tank or a fuel tank, consider what it will be used for and whether it will be placed above ground or underground. This helps in the decision about what type of tank to purchase, whether that might be fiberglass, polyethylene or metal.

Size is another very important consideration because the size of a tank purchased depends on available storage space and your needs. Water tanks purchased for drinking water may be smaller than tanks purchased for irrigation, and fuel tanks purchased for gasoline might be much larger than those purchased to store antifreeze.

Above Ground Tanks Vs. Underground Tanks

Whether for holding water, gasoline or other liquids, storage tanks installed above ground are easier to fill. Because many above ground tanks are made from plastic, they are typically less expensive than underground tanks. In addition, excavation is not required, so installation is less costly. One disadvantage of above ground tanks is the amount of space they require.

Underground storage tanks make a good alternative if you have limited ground space or for areas exposed to harsh weather. However, people who intend to store fuel in underground tanks should be aware of any regulations in their area. Tanks installed underground that contain gasoline, heating oil or other hazardous liquids may require safety checks or permits because of a potential for leaks or accidents that can affect soil and groundwater. These rules and regulations usually pertain to tanks equivalent to or above a particular size.
