Septic Tanks FAQs, answered by experts

You can find your septic tank using a few different methods. For one, you can check your property records at your local municipal office. You can also inspect your yard looking for a depression, a septic tank lid, or lush septic-area vegetation which would indicate a leach field. You can also follow your pipes from the home to the yard. If you can't find your septic tank on your own, a local septic pro can help.

Most home wells start at 100 feet, and many go as deep as 200 or 300 feet. 

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’s often better to drill slightly deeper and give yourself a bit more water storage than you need.

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

While not strictly necessary for your septic system to operate, septic tank risers are a highly beneficial and wise choice for homeowners. They provide easy access to your tank, which makes regular maintenance, inspections, and addressing issues significantly easier and less labor-intensive. By eliminating the need for repeated excavation to locate the tank, risers can save you money, labor, and energy in the long run. This easy access allows you to proactively manage your septic system, addressing potential problems before they become costly and ensuring the system's longevity. Additionally, some local regulations may require risers, and installing them can help you avoid potential fines or penalties.
