Septic Tanks FAQs, answered by experts

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

Watch for slow drainage, pooling water in the yard, or unpleasant odors inside or outside. Addressing these issues timely avoids significant disruptions or costs.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.
