Q: How deep should a septic drain field be?

• <div><p>The ideal depth of a septic drain field is <b>18 to 36 inches</b> below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.</p></div>

Q: Does rainwater go into my well?

• <div><p>Rainwater doesn't have a direct impact on the amount of water in your well. Instead, the majority of rain runs off into other bodies of water such as streams, rivers, and lakes. These bodies of water may sometimes function as the area&rsquo;s reservoir and create aquifers, which then help to replenish your well.</p></div>

Q: What happens if your septic tank is the wrong size?

• <div><p>The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task&mdash;and if it&rsquo;s far too large, there won&rsquo;t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.</p></div>

Q: What types of drainage systems are available?

• <div><p>French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property&rsquo;s needs.</p></div>
