I am planning to build a new construction SFH in Tennessee and was curious how much I should budget to purchase and install a conventional septic system? I have heard numbers from $6K-$15K. We want to make sure our budget is as close to the final number as possible. Thanks for your help!
To make sure it’s as close as possible, get some written bids.
@Carl Murray right now we just want to have a rough estimate to start while working toward a more formalized budget. A ball park number would be sufficient.
I just had my septic Sub-Contractor put in one a year ago. 3BR house. Large leach field. $12k
It's best to get the county to do a soil analysis which should be a requirement. Once that is complete, you can send to a couple of septic installers to get some bids. Conventional and chamber systems are the most affordable. Here in NC, I normally spend approximately $4500 for either but if the soil is poor if you have limited space, it could get a lot more expensive.
