How to Estimate Septic System Costs

In urban areas, the municipal sewage treatment plant handles wastewater treatment. Homes and buildings in rural settings, however, need a well-constructed septic system to handle their wastewater treatment needs. Homeowners in the countryside often find themselves asking, “Exactly how much does a septic system cost?” 

The exact price depends on many factors, such as the system’s location, type, and size. These variables, along with additional costs for maintenance and repairs, contribute to the overall price.

Tank Location

When planning a septic system installation, location should be your first consideration. When you add in the costs of plumbing costs, site preparation, and additional plumbing, you’ll realize the location is one of the most critical factors in calculating your septic tank installation costs. For instance, plumbing can significantly increase your total septic symptom expenses, with every 100 feet of septic-appropriate PVC pipe costing an average of $65 to $80.

Tank Site

The size of your septic tank and the treatment method you want to use are the next elements to consider. Aerobic wastewater treatment methods require less leaching space, but they are much more expensive than the less effective aerobic septic treatment systems. Variations in tank sizes also significantly contribute to your septic tank installation cost. The most popular tank sizes are 1,000-gallon tanks and 1,500-gallon tanks. Smaller homes could need as small a tank as 800 gallons. 

Tank Design

Your final consideration for the cost of septic system installation should be the tank design itself. Having a professional engineer design your system, even if it adds cost, is well worth it. Repair-related expenses from a flawed design outweigh the expense of hiring a professional septic system designer. Tank materials matter, too. Inexpensive polyethylene, popular concrete, or premium fiberglass are all options, although polyethylene tanks are not allowed in all states. 

There are many items that can affect prices for septic tanks and septic systems. These three, however, are the big-ticket items that have the greatest impact on the cost of septic systems. If you have a good idea of what kind of system you need, what size tank you want, and where you want to install it, you’ll be able to answer the question: “How much does a septic tank cost?”
