Septic Tank Pumping and Emptying

septic tank cleaning and emptying

Septic tank pumping and emptying is the process of cleaning the tank from liquid and solid wastes. In the cleaning process, all the waste materials have been removed that are responsible for the buildup of sludge and scum layers. It is recommended to regularly inspect your tank to make sure it’s running well. On average, a tank should be inspected every 2 to 3 years and must be cleaned between 3 to 5 years. However, before going deep into the topic of septic tank pumping and emptying, let us have some knowledge of what a septic tank is.

What is a septic tank or septic system?

A septic tank is a chamber usually made up of concrete, fiberglass, or plastic. It’s an underground container used for the treatment of domestic wastewater (sewage). Septic tanks can be used in areas that are not connected to a sewerage system, such as rural areas. The septic usually consists of two compartments. The solid wastes from the wastewater settle down in the first compartment. The liquid waste travels to the next compartment. The solid waste in the septic tank is responsible for scum and sludge buildup.

How does it work?

The term “Septic” is defined as the anaerobic bacterial environment that develops in the tank. It is responsible for the breakdown or decomposition of the solid waste material in the tank. Septic tanks can also be installed with other wastewater treatment units. Such as biofilters or aerobic systems, commonly used for artificially forced aeration.

In the settling process the solid waste settles down in the tank and liquid waste is passed to the other chamber. Similarly, anaerobic processes reduce solids and organic wastes. This process is known as primary treatment. The efficiency of primary treatment is only moderate.

The rate of accumulation of sludge is known as septage or fecal sludge. This process is faster than the rate of decomposition. Therefore, the septic tank needs to be cleaned out manually and it’s done with the help of vacuum cleaning.

The wastewater runs down to the septic tank through the septic drain field, which provides further treatment. But a disadvantage commonly seen is groundwater pollution may occur and can be a problem.

Does a septic tank need pumping?

In order to keep your septic tank running efficiently, it is recommended to pump out your tank on regular basis. If the tank has not been cleaned too long, it may result in septic system failure. As a result of failure, the system will start clogging and wastewater will start leaking out from drains. It will start polluting the environment and cause serious health issues. It is also against the law for using a septic system. If an inspector acknowledges this, he will be able to punish you according to law and ask you for tank replacement. The tank replacement process is very costly. So, it is better to take care before it is too late.

How often should a septic tank be pumped?

Once you installed the septic tank, it still needs care and regular inspection. As there is a saying, “Care is better than cure”. So keep inspecting your septic system on regular basis. On average, a septic system must be inspected after 3 years. However, if your system is installed with mechanical components, it needs more frequent inspection. It’s recommended to inspect it every year for avoiding problems.

On average, a septic system needs to be cleaned out every 3 to 5 years. However, a septic system still needs to be inspected regularly. Generally, the time range depends upon different factors. Four major factors that are responsible for time variation are:

  1. Size of the septic tank.
  2. Size of the household.
  3. Amount of wastewater generated.
  4. Amount of solid wastes in the septic tank

When a professional inspector comes, he will inspect for sludge and scum layers in the septic tank. If the upper scum layer is 6 inches from the basic outlet pipe, the system needs a cleaning. The same is for the lower sludge layer, when it is 12 inches from the basic outlet pipe, the system needs to be pumped out. Always keep the records of inspection and cleanings to keep tracking the time for the next cleaning.

Signs for the septic need of pumping out:

If you haven’t pumped your tank in the last 3-5 years, it is a good idea to schedule a septic tank cleaning. Pumping the tank every few years ensures the tank doesn’t get full because if it does, it might start backing up or leaking which ultimately leads to pollution of the environment. But before you schedule a pumping, you could do a scum and sludge level test first. This will help you to establish if your septic system is really full. Here are some signs when your system needs to be pumped out:

  • Clogged drain field
  • Sewage backup
  • Water backflow
  • Clogged drains or toilets
