"Noticed we were starting to have issues with our septic tank. Gave Thigpen a call and set up an appointment for the next day. They were here on time and completed the job quickly. No trying to talk me into any other services I didn't need, no bs, just straight up honest work. Will definitely hire again when the time comes."

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.

The best way to keep a septic tank clean is to hire a local septic tank cleaner to inspect and pump the septic tank every three to five years. Be sure to only flush human waste and toilet paper down the toilet, and don’t pour grease, oil, fats, coffee grounds, or food scraps into your drains.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

Cisterns can be used as septic tanks, but septic tanks can’t be used as cisterns. This is because cisterns need to meet FDA standards for drinking water, but septic tanks aren’t required to meet those standards since they are only used for wastewater.
