Understanding your septic system


A septic system is the most common private sewer system. This application is used when city sewer systems are not available for connection when a house is built.
There are various septic applications, but the best known Is a conventional septic system. A conventional septic system is the most common largely due to easier installation and cost. It is comprised of:

  • The drainage pipe that carries waste from your home to the septic tank;
  • The septic tank, which serves as a holding tank where heavy  solids settle to the bottom and lighter material floats (heavy solids are known as sludge and the lighter material is known as scum) and lastly,
  • A drain field or leach field, which consists of a network of pipes in trenches underground, which allows liquid waste, known as effluent to be dispersed into the soil.
The majority of the material that enters the tank is in liquid form. Inside the tank, most of the solids are turned into gases or liquids. The breakdown of the solids is due to bacteria action. The liquid then is dispersed into the drain field
If a septic system is not working properly, it can pose a health hazard and should be corrected as soon as possible. Homeowners should keep an eye out for water pooling above the drain filed or strong odors coming from the field. The overloading of the drain field, soil breakdown, high water tables and leaking tanks are all problems that can lead to system failure.
Septic systems, if possible, should be a safe distance from water supply sources. If your home has a septic system, it is imperative that you maintain it to keep it running as efficiently as possible. The system should be inspected annually and the tank should be pumped every two to five years, or as recommended by the manufacturer.
Strong detergents should not be allowed into the septic system. This will cause the bacteria inside the tank to be destroyed. Homeowners also should consider keeping too much water from flushing out the system. If too much water floods the system, it can cause solids to perolate into the ground without being broken down by the bacteria
If proper servicing and maintenance is followed for your septic system, you can look forward to efficient waste treatment for years.
