The Cost To Install A Septic Tank


The cost of installing a septic system in New England varies depending on the size and location of your property, but typically ranges from $8,000 to $14,500. These prices do not include any permits or inspections required by the local government. While this may be an expensive upfront investment for some homeowners, it is often helpful to look at the long-term savings that you will have as a result. For example, one study estimates that septic systems can save up to 25% a year on water and sewer bills compared with traditional sewage systems because they use less resources per person than traditional systems do.

The benefits of A Concrete Septic Tank Over A Fiberglass Tank

With concrete septic tanks, the septic tank is made of a thick, solid concrete that will not crack or break over time. Fiberglass tanks are often constructed from two pieces and have an increased risk of breaking down faster than concrete tanks do.

For example, when fiberglass septic tanks age they may show signs of cracking as well as developing hairline fractures in the tank. Concrete tanks, on the other hand, are less likely to crack and will not develop hairline fractures.

Concrete tanks also last longer than fiberglass septic tank because they’re made of a thick material which is stronger and more resistant to breaking down over time. In addition, concrete septic tanks may be able to store up to six times as much wastewater before leaking becomes an issue while fiberglass septic tanks can only hold about one gallon per square foot. 

In many cases it’s a good idea for a homeowner who has a concrete septic system in place already to just replace portions of their piping systems- without replacing the entire system- if there are problems with water infiltration or leakage due to corrosion. Replacing a tank can also be a good idea if there are problems with the septic system that cannot be fixed; for example, leakage from around the top (due to corrosion) or up through slits in the bottom of fiberglass tanks.

Integrity of Concrete Septic Tanks

In harsh New England weather with freezing temperatures, a concrete septic tank will be vulnerable to cracking and disintegrating. The integrity of concrete septic tanks can also deteriorate if they are not properly maintained, leading to leaks in the tank or at joints that have been poorly sealed with a rubber sealant.

While many homeowners will choose fiberglass for their septic system because it is cheaper than concrete, metal, or PVC piping systems, there are some drawbacks as well: Fiberglass tanks cannot hold up under freezing temperatures like other materials- so these types of septic systems should never be installed during winter months in New England when ground water levels reach their lowest points. In addition, due to its light weight, a ruptured fiberglass tank could cause significant property damage from a leaking sewage leak on topsoil or into a basement.

Installing A Concrete Septic Tank

The time to install a concrete septic tanks is about the same as installing a fiberglass septic tank. While this material is more expensive, it does offer some advantages: In New England’s winter months where ground water levels reach their lowest points and will freeze a concrete septic system can handle cold temperatures without cracking like other materials.

It is also heavy enough that if there were to be leakage from any part of its surface, the likelihood of property damage would be significantly lower than with lighter weight systems.

Commercial Versus Household Septic Tanks

In New England, the difference between a commercial and household septic tank is in size. A commercial septic tank is much larger and can hold between 20,000 to 60,000 gallons of liquid waste while a household septic system would not be able to exceed the capacity of 4000-6000 gallons.

Commercial septic systems are also used when more than one family resides on property with each person having their own bedroom or living space. In this type case it becomes necessary for these occupants to have their own sewer line running from the building directly into the septic system’s drainfield so that they do not contaminate another area where people reside.

The advantages of installing a concrete septic tank over a fiberglass tank are clear. Fiberglass septic tanks can crack, and in some circumstances it is possible for the cracks to become so serious that groundwater infiltrates into them. Concrete septic tank are made of a single piece of concrete with little or no joints where water could infiltrate and cause cracking.
