What causes a septic tank to collapse?

• <div><p>There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots. </p></div>

What does a septic tank look like?

• <div><p>Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of <a href="https://www.angi.com/articles/how-big-is-septic-tank.htm">septic tank sizes</a>, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.</p></div>

Q: How deep is the average home water well?

• <div><p>Most home wells start at <b>100 feet</b>, and many go as deep as <b>200 or 300 feet</b>. </p><p>It takes quite a lot of water to meet the demands of showers, toilets, faucets, and appliances like dishwashers and laundry machines, and shallow wells struggle to provide this amount quickly. If you anticipate having high water usage in the future, it&rsquo;s often better to drill slightly deeper and give yourself a bit more water storage than you need.</p></div>

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: How is a septic perc test done?

• <div><p>A septic perc test is done by drilling a hole into the ground, filling the hole with water, and testing to see how long it drains. While simple, the test itself provides a great deal of information about your yard. The last thing you want to do is skip a perc test only to discover your yard doesn&rsquo;t drain sewage effectively. </p></div>
