Overview of Septic Tanks

A septic tank

A septic tank is an underground chamber made of concrete, fiberglass, or plastic, used in rural and suburban areas where centralized sewage systems are not available. It forms the heart of an individual septic system by treating wastewater from homes.

The tank operates by separating and breaking down solid wastes, while the effluent drains to the drain field. The process leverages bacteria to dissolve the solids into liquids that can be environmentally safe.

A septic system

A septic system is necessary where properties do not have access to public sewer lines.

It allows for the safe disposal of wastewater, reducing the risk of diseases from untreated sewage and protecting the environment.

The primary components of a standard septic system include the tank itself; the inlet and outlet pipes; the drain field, which is a subsurface wastewater disposal area; and the soil, which naturally filters and treats the wastewater before it rejoins the groundwater system.

An Overview of Septic Tank Installation Costs

The process of installing a septic tank comprises various details that have long-term implications for both functionality and cost.

Careful consideration of factors such as the type of tank, inclusion of manhole covers, pipe installations, possible permits, site excavation and labor costs is essential to prevent environmental and financial repercussions down the line.

You should also plan for a drain field if needed, and any post-installation landscaping requirements. It’s worth noting that prices can fluctuate wildly due to the preferred tank size, the complexity of the installation site, or specific local ordinances.

As the tank’s size increases, so do the materials and labor needed, potentially necessitating specialized equipment, thus hiking up costs.

Even the material of the tank itself can dictate the final tally. For instance, septic tanks made of concrete often command a higher price than their plastic or fiberglass equivalents due to their enhanced strength and longevity.

Factors That Affect Septic Tank Installation Costs

There are a multitude of elements that collectively determine the total fee for septic tank installation.

Among these factors are the tank’s size, material, and several other associated costs. Firstly, local permits and inspections are typically required and carry individual charges.

These include application costs, inspection fees, and in some cases, expenses for connecting to the local sewage system. Site preparation, which includes clearing the area, testing and possibly modifying the soil, and excavation work, essentially contributes to the overall cost as well. Last but certainly not least, labor, which constitutes executing the actual digging, placing the tank, and linking it to the house’s plumbing, can make up a large portion of the final invoice.

The complexity of the task will often define how many days a team of professionals will need to complete the installation.

Steps In The Installation Process

The Procedure of Septic Tank Installation

The process of setting up a septic tank kicks off with the crucial steps of obtaining the necessary permits and permissions, which usually involves a soil percolation test to analyze the absorption capacity of the soil in the proposed installation area. Once the chosen site receives approval, the excavation of the designated area begins.

The size of the excavated area generally corresponds to the size of the tank, which is calculated based on the number of bedrooms in the residence. The excavation phase contributes significantly to the overall costs due to the implications for labor and equipment requirements.

Costs and Installation of the Tank

Once the site has been prepared, the septic tank is installed. Plastic, concrete, or fiberglass tanks are most commonly used. Concrete tanks, due to their resilience and long lifespan, are the most expensive.

No matter the material chosen, the tank needs to be correctly positioned and connected to the house via a series of pipes. After the tank is set, a drain field is created through which effluent from the tank percolates into the soil.

The nature of this drain field construction will depend on local codes and the percolation test results, which can further affect costs.

Post-Installation Testing and Finalization

Once the septic system is successfully set up and the drain field established, it’s crucial to carry out a thorough examination to ascertain the whole system is functioning correctly. Should issues arise during this testing phase, potential extra costs in the form of adjustments and repairs might add up.

The area is afterward backfilled, and the landscaping can be returned to its previous condition. The final cost of septic tank installation hinges on multiple factors such as the tank size, soil type, local regulations, and the complexity of the installation process.

Comparing Different Types of Septic Tanks

Considering Concrete Septic Tanks

Concrete septic tanks come with several advantages, with durability standing out prominently.

With proper attention and maintenance, these tanks can serve for numerous decades. Their significant weight also curtails tendencies of floating. Nevertheless, there lies a risk of developing leaks or cracks if not correctly installed or maintained.

Concrete tanks could also be pricier compared to other alternatives because their size and weight increase labor and installation costs. For example, buying the tank alone could cost anywhere from $1,200 to $2,500, with installation costs incrementing the overall expense.

Plastic Septic Tanks

Plastic septic tanks, on the contrary, are less expensive to purchase and install compared to concrete tanks.

They are lightweight, reducing the cost and labor needed for installation.

These tanks range between $800 and $1,300 in price, proving to be cost-effective solutions in the short term. However, plastic tanks are not as durable as their concrete counterparts and may become damaged over time due to soil pressures, needing replacement more frequently.

Additionally, if not properly anchored, they can float to the surface in areas with high water tables, resulting in added repair costs.

Fiberglass Septic Tanks: An Affordable Option

For those seeking a balance between affordability and durability, fiberglass septic tanks prove a popular choice. Robust than plastic alternatives, though not as much as concrete options, these tanks align with most homeowners’ budget.

Generally, fiberglass tanks cost between $1,600 and $2,000, broadly the same price range as plastic ones but less expensive than concrete models. However, this cost typically excludes installation expenses.

A prudent precaution to protect the longevity of a fiberglass tank is ensuring that no heavyweight vehicles or equipment pass over the area of installation, as fiberglass tanks can suffer damage due to intense pressure.
