Septic Tank Installation Cost: A Basic Pricing Guide

There are many things involved in getting septic tank installation cost estimates, so it’s impossible to give a written comprehensive estimate that’s suitable for everyone. If you need to work with hard numbers, give us a call right away, so that our experienced technicians can look into your specs and requirements, to make sure the estimate is suited to the type of system you need. With that said, this page can help serve as a general guide if you’re just getting started on your information quest.

Is it New or a Replacement?

The term “septic tank installation” usually refers to just the reservoir that works as the system’s first stage of processing. If you don’t already have a system, which includes a leach field or other absorption area, there’s more involved than just purchasing a reservoir. Please see ourCost of Septic System page. The rest of what you’ll find here pertains to the tank only, perfect for homeowners who have an existing system and need to replace just the tank.

Are You Sure You Need a Replacement?

Before getting into expenses, it’s important to note that tanks usually last decades. It’s very common for those made from cement to last 40 years or more.  If your system is failing, it’s probably not a problem with the tank, itself. Call us and we’ll send our qualified technician out to diagnose what the problem is or check out our guide to common septic tank problems, so you can narrow down what part of the system could be causing the issue.

Information Needed in Determining Septic Tank Installation Cost

  • Size: Most residences find a 1,000-gallon reservoir to be acceptable. It’s generally ideal for as many as six people or up to a four-bedroom home. If a fifth bedroom is in use, a 1,200-gallon size is usually needed, and a 1,500-gallon size is better for six bedrooms. There are regulations that specify the minimum size you can choose, for the sake of health and safety, but if you have normal water usage and an average-sized family, the 1,000 should do. Speak with a professional to make sure you’re looking at the right sizes for your home and needs.
  • Material: Most tanks are made of cement, with fiberglass coming in a close second. These are a little more expensive than their plastic counterparts but are also more durable. As a basic guideline, a 1,000-gallon cement reservoir is likely in the neighborhood of $1,000-1,200.
  • Permits: Changing out any aspect of your system requires permits, as the county is going to want to be sure your designs are safe and that you’re using approved materials. Count on these running $100 or so.
  • Disposal of the Old Tank: If you’re dealing with the replacement of a tank, the old one will need to be taken care of as well. Lightweight ones can often be removed and disposed of. Cement reservoirs are typically crushed in place and backfilled. In this case, a new hole will need to be dug for the replacement unit.
  • Labor: Labor is another cost that will be included, but it is totally dependent on the amount of work that needs to be done in order to get the replacement tank in, as well as up and running.
