How long will a mound septic system last?

• <div><p>A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual <a href="https://www.angi.com/articles/what-is-a-septic-inspection.htm">inspection</a> of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.</p></div>

Can I add dirt over a septic field?

• <div><p>Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability. </p></div>

Q: What is the downside to a septic system?

• <div><p>While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.</p></div>

Q: How deep should a septic tank be buried?

• <div><p>How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. </p></div>

Q: What types of well pumps are available?

• <div><p>Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.</p></div>
