Know Your Septic Tank

Know Your Septic Tank

Most homes in urban areas are hooked into their city’s sewer system. That means that all waste from those homes goes to the local sewer treatment plant where it is processed. However, in many rural areas, homes are built far from any sewer treatment facilities, so they must use alternative methods of waste disposal. Nearly all those homes have individual septic systems. These are self-contained treatment units that are nearly maintenance-free, except for a few important tasks, which must be performed periodically. For example, septic tank pumping must be done about every two to three years, depending on how much the system is used. When you need to have your septic tank pumped, our experienced Roto-Rooter technicians will take care of it.

How It Works

Your septic system essentially contains four parts. Each has a specific function.

  • A sewer pipe from the house to the septic tank delivers all waste products from toilets, tubs, and sinks to the septic tank.
  • The septic tank collects all waste products. The solid waste (sludge) settles to the bottom of the tank. The greases and fatty substances (scum) rise to the top. The liquid (effluent) flows out of the tank and into the drainfield through an effluent pipe.
  • The effluent pipe is a standard pipe attached to the septic tank using a sanitary tee outlet.
  • The drainfield is where the effluent ends up. This liquid still contains germs that are hazardous to the health of humans and animals. Thus, it has to be processed, and that is done using the soil. The drainfield contains perforated pipes that allow the effluent to filter and drip down into the soil. With time, all the bacteria and viruses are killed by the soil and absorbed in the natural underground environment.
