pros and cons of mound septic system

  • A Good Alternative

It works perfectly fine where traditional at-grade or the in-ground septic system won’t work. If you have a decent budget, a mound septic system can be your best alternative to the traditional septic system.

If your soil does not pass the test required for a traditional septic system, you can have the mound septic system irrespective of the soil absorption level.

  • Relatively Inexpensive

It’s expensive than the traditional septic system but less expensive than a custom engineered septic system. Also, it will cost you less for repairing than other septic systems.

In a mound septic system, you just need to reset it by turning over the ground and digging out again. So, it’s economical in the long run.

It won’t contaminate the nearby water source since it does not discharge the waste directly to such a source.

So, it’s a good system to protect the water table. In fact, it protects the water table better than almost any other septic system.

This is how…

Unlike the conventional septic system, it has an additional filtration mechanism to treat the waste. It releases the clean effluent to the water table after a rigorous filtration process.

  • Great Backup Replacement

It will work as your ultimate savior when the main system fails. As a replacement system, you will need less land but it will help you to meet the health dept. regulations and building codes.

  • Mound septic system is always more expensive than its conventional septic system counterpart. It’s a time-consuming and labor-intensive task. So, extra cost is a must.
  • Also, you need to buy a pump to pump the effluent. It requires other components and equipment that need to be maintained properly too.
  • Requires highly sophisticated construction. If not careful, you or the contractor may damage the topsoil.
  • If you don’t work on your landscaping option, the appearance of mound system won’t be so pleasant! Once installed, it’s nothing but a mound of dirt!
  • If any of the system components fail, you will experience backups and other problems since this is not a gravity fed system.
