Differences Between Cesspool & Septic

Septic wastewater systems handle residential and commercial sewage. They include a variety of individual and cluster treatment systems. An estimated 20 percent of United States households use septic systems as of 2011, according to the United States Environment Protection Agency. Older houses and commercial space often have cesspools, while new houses and commercial space built during the mid-1970s or after have septic tanks for septic wastewater systems.
  1. Wastewater in Cesspool

    • A cesspool unites the septic tank and the absorption system into one device. It consists of a hole dug in the ground to collect sewage. The sewage travels from the home or commercial space into the tank, and liquid flows through cracks in the concrete block or stones laid with a cesspool. Wastewater goes into the cesspool and seeps into the earth through the cracks in the wall. In addition, a tight cover goes on top of a cesspool to keep insects and other critters from getting in the cesspool. Cesspools are also called "leaching pools."

    Pros and Cons

    • People have opted for cesspools for centuries. Though they are inexpensive to install, they can easily contaminate surrounding areas such as earth, wells and water supplies. However, a septic-tank sewage system is an alternative to a cesspool, since you can use the water nearby, farm or perform other activities without contaminating the area. A septic tank sewage system includes a house sewer, house drain, septic tank, disposal field and distribution box.

    Wastewater in Septic Tanks

    • All wastewater for a house or commercial space passes through chamber known as a septic tank. The tank stores the wastewater, and the solids fall to the bottom of the unit, creating sludge. Detergents, soaps oil or lighter solids float to the top, forming scum. Eventually, the solid waste breaks down with the help of natural bacteria.

    Septic or Cesspool Location

    • You can find the location of your septic tank or cesspool by looking at your property survey. The property survey denotes a cesspool location with a circle and a septic tank with a rectangle. In addition, your city or county's building and health department likely has a copy of your property survey if you constructed your house after 1975.

    Septic Systems before 1975

    • Typically, septic systems installed before 1974 are most likely cesspools. Before 1975, cesspools were normally made of cement block or bricks. With this type of construction, you can run into numerous problems with your cesspool, which can result in a collapse. Due to this issue, children, pets and adults should not walk or play near a cesspool. In addition, do not park heavy machinery, automobiles or boats near this location. You may desire to update the cesspool with a more modern septic system.
