All You Need to Know About Septic Tanks Clogs

Apart from the electricity, gas, and plumbing system, every house also has its drainage system that allows the wastewater to drain to its right destination. This drainage system is fundamental to keep up with the sanitation and cleanliness of the area. Many urban areas have their sewage system through which the waste of its site and surrounding areas are collected from the cities and towns and transported through the developed system. This system is mostly maintained and operated by the water company in your local area.

For areas where this system is not much developed or considered rural, have another source through which waste materials are collected and transported to its designated locations. Most commonly, a septic tank is used. A septic tank is a tank that is installed underwater. It is a sedimentation tank that is used for wastewater treatment. The process followed in this tank with the wastewater is composed of a biological decomposition and drainage system.

Because of their quality and feature of safe disposal of wastewater, these tanks are one of the most popular and most sought out options in areas or localities where the drainage system is low or are off the leading sewage network. What a septic tank does is that it collects all sorts of wastewater and excreta in its underground tank and then works on its decomposition process, which is why it is predominantly used in rural areas.


Design and working of a septic tank installed and used in a home.


A septic tank has a simple design which is mostly rectangular or round. It is a watertight container installed underground and comprises any of the three materials; plastic, fiberglass, or concrete. For the inlet and outlet of water, two pipes are connected with this tank that allows water flow. The line leading towards the septic tank from the whole house, the inlet pipe, collects all the wastewater and directs it towards the tank. While the water is being led to the tank, it is long enough to give reliable and liquid waste time to get separated from each other.

The outlet pipe has its function as it leads the pre-processed wastewater from the tank outside and spreads it evenly in the watercourses and the soils where it is needed. This pipe that leads the water out from the tank is also called a drain field.


Separation of wastewater in a septic tank

The wastewater collected inside the septic tank with the inlet pipe’s help is separated into three layers after it stays in the tank for a while.

The top layer that formed is usually oils and grease, which is lighter in weight and therefore floats above all the waste that has been collected. This layer is called scum. The next layer, the middle layer, consists of all the wastewater and all the waste particles. Lastly, the third layer that is formed at the bottom of the tank is the one that consists of more massive particles that are heavier than all waste materials and water and hence form a layer of sludge.

Apart from the formation of layers, another process inside the tank includes the breaking down of the solid waste. All this waste is broken down and decomposed rapidly with the help of bacteria present in the wastewater and allows the liquids to separate and drain away more quickly.


Possible causes of slow drainage to the septic tank

There are many reasons why a drainage pipe of the drainage system leading to the septic tank can get clogged. Some of the most common reasons are highlighted below:

  • Any part of the two main lines, the inlet pipe, and the outlet pipe, of the septic tank that connects it to the house and the area outside, are partially or fully clogged.
  • There is a chance that any part of the percolation pipes has clogged.
  • The vent attached to the septic tank used as air duct purposes has blocked due to some reason.
  • Because of low temperatures, the septic tank or septic vents or some areas have frozen, causing a blockage in wastewater flow.
  • There might be some blockage in the distribution box.
  • There is a possibility that a small or significant part of the main drain line clogged because of the wrong items that have flowed the drain.

Ways to unclog the main drain or full septic tank

– One of the most common tools used to unclog the drain that leads to the septic tank is to use a drain snake or water jetting that leads to the main drain pipe. You can try on your own if you have some knowledge about it or hire an expert for these services.

You can also unclog the main drain by looking for any possible blockage in the distribution box. This distribution box is what is located between the septic tank and the percolators. There are chances that a backup of any sort has formed in between. If so, then make sure you remove it and check for the easy flow of water.


– You might also want to check the percolators and the area around it. See whether it is moist, swampy, and stinky. It means that the percolation is not proper. In other words, the soil is not absorbing the drain water at the rate of discharge. This bottleneck over here can cause the water to only reach the ground near it, and once the capacity for the soil to absorb water has reached its maximum, it would start to create a blockage. This blockage either happens because water usage increased due to more guests, or the soil has become saturated due to moisture from other sources such as rainfall (more than usual). To handle this issue so that the water is distributed evenly from now onwards, immediately call for an expert as this is a problem that requires instant care.
