Septic Tanks questions, answered by experts

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

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.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

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.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.
