Factors Influencing The Installation Costs Of A Septic Tank System


A sewer tank provides a reliable way of disposing of sewage and treating it if you lack access to a centralized sewer line. However, without adequate information regarding sewer systems, you may incur hefty installation costs that may not necessarily match the tank's quality. Thus, it is wise to engage a plumbing expert to take you through the pre-purchase and selection of your sewer tank. With the help of an expert, you will incur fewer costs and get an appropriate system. Below are factors impacting the cost of septic system installation. Read on.

The System's Location

Above-ground tanks are cost-efficient to install as their construction is not disruptive and not labor demanding. Conversely, underground tanks are more expensive to install since they involve excavating a large hole to accommodate the tank. Besides, you'll need to install a drain field, pipes, and distribution box. And if the gradient of the land is steep, you will incur a higher cost than flat terrain. Also, you might pay more for the installation if you have to get rid of trees and large-diameter rocks to prevent root infiltration and provide a stable base.

The Tank's Size

Typically, the septic size will depend on the size of your household. Thus, if the number of occupants in your house is big, you will require a bigger tank, hence a high upfront cost. Nevertheless, that means lower upkeep costs since a large tank does not need as much pumping as a small one. But on the other hand, small tanks are more economical to install due to less manpower and a shorter construction time. Contact a plumber to determine your projected water usage before purchasing a tank. They will also assess your needs and suggest a septic tank with the capacity to meet your demands.

The Tank Type

Septic tanks vary depending on the material used to craft them and how they treat waste. For example, concrete tanks are cheaper than other materials, although they are susceptible to cracking if you fail to maintain them. Plastic tanks are also relatively inexpensive. On the contrary, high-quality systems such as fiberglass and aerobic tanks are more expensive to install due to the intricacy of their construction. Since the quality may vary between models of the same material, you should consult a plumber to recommend the appropriate septic tank.

The Drainage Network

If you opt for a below-ground tank, you may incur the extra costs of fitting a soakaway. This system will allow effluent filtration, ensuring less frequent pumping. Furthermore, if the tank sits lower compared to the drain field, you will incur more costs than a septic pump since gravity cannot facilitate waste flow.

Despite the high cost of installing a septic tank, understanding the above factors can help you reduce the overall cost. But the best way to keep your budget under control is to work with a plumbing expert.
