A septic tank is an underground wastewater treatment system that is used in areas that are not connected to a municipal sewer system. Septic tanks are designed to treat wastewater from toilets, sinks, and other household fixtures. The tank is made of concrete, fiberglass, or plastic, and it is buried underground.
How Does a Septic Tank Work?
Wastewater from your home enters the septic tank through a pipe. The wastewater then flows into the tank, where it is separated into three layers:
- Scum: The scum layer is made up of fats, oils, and greases. It floats to the top of the tank.
- Liquid: The liquid layer is made up of water and dissolved solids. It is located in the middle of the tank.
- Sludge: The sludge layer is made up of solids that have settled to the bottom of the tank.
The scum and sludge layers are broken down by bacteria that live in the tank. The bacteria convert the organic matter in the wastewater into carbon dioxide and water. The treated wastewater then flows out of the tank through a pipe and into a drain field.
What is a Drain Field?
A drain field is a network of perforated pipes that are buried underground. The drain field is where the treated wastewater from the septic tank is discharged. The wastewater seeps into the ground, where it is further treated by bacteria and other microorganisms.
How to Maintain a Septic Tank
Septic tanks require regular maintenance to function properly. The following are some tips for maintaining your septic tank:
- Pump the tank every 3-5 years. This will remove the scum and sludge that has accumulated in the tank.
- Inspect the tank and drain field annually. Look for any cracks or leaks.
- Don’t put anything down the drain that can damage the septic tank. This includes things like grease, oil, and harsh chemicals.
- Conserve water. This will help to reduce the amount of wastewater that flows into the septic tank.
What are the Signs of a Failing Septic Tank?
The following are some signs that your septic tank may be failing:
- Slow drains. This is a sign that the drain field is clogged.
- Backups in the toilets or sinks. This is a sign that the septic tank is full.
- Bad odors. This is a sign that the septic tank is not treating the wastewater properly.
- Pooling water in the yard. This is a sign that the drain field is not working properly.
What to Do if Your Septic Tank Fails
