"The service technician was 2 hours late and his price was $1900, I decided to get a second quote and I am so glad I did. I got the same job done with better tank and filter for $1100. My advice is get a second quote if you have time, I saved $800 by using another company."

Septic Tanks questions, answered by experts

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

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.

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

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—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

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.
