How Much Does a Mound System Cost

A mound septic system costs $10,000 to $20,000 to install. It’s the most expensive system to install but often necessary in areas with high water tables, shallow soil depth or shallow bedrock.

How long does a mound septic system last?

The short answer is: septic systems tend to last anywhere from 15 to 40 years. It’s a large range, but that is because the average lifespan is entirely dependent upon a lot of factors.

How much room do you need for a mound system?

Unlike conventional systems the mound system will require two separate tanks. The first will be a standard septic tank buried at a depth of 10 to 16 inches and located a minimum of 10 feet from the foundation of the house. Both tanks need to be level and square.
