Septic Tanks Are Back In! Here’s What You Need to Know About How They Work
Introduction of Septic Tanks
In a city, houses and apartments are designed to follow a sewage system. Many houses and apartments share the same sewage, and this waste is then either discharged into a running river or some barren area such as a field.
The reality is that this wastewater can get contaminated along its public journey of waste collection and disposal.
Over the past few years, many people have started moving back to the suburbs or boonies, looking to escape densely populated areas in an effort to find tranquillity.
Some have also taken notice of environmental hazards that are harming nature and natural habitats around us. With these trends, septic tanks have returned to help homes get rid of waste as well as protect the environment.
If you are one of these people looking to escape the city and begin using a septic tank, it’s important you understand how septic systems work. You’ll be impressed by their design, efficiency, and environmentally-friendly process.
What Is A Septic Tank?
A septic tank is an underwater tank installed in a household that is used to treat the wastewater and remove toxins from it before it is drained in nature or recycled. It really is a perfect combination of technology, engineering, and biological reaction.
Benefits of Septic Tanks
There are a few benefits associated with septic tank systems. For one, septic tanks are environmentally-friendly. They do not contaminate the surrounding natural resources around them.
Septic tanks are also cost-effective. A single septic tank can go on for decades if it’s maintained properly, which includes getting it regularly pumped and making sure only the correct substances go into the tank.

Design of a Septic Tank
A septic tank is normally made of fibreglass, plastic, and even concrete. Often, there are two chambers located in the tank which are divided by a wall.
The larger chamber holds the wastewater while the solids settle in the smaller chamber. There are compartments in the tank and an outlet in a T-shape that acts as an outlet for water. Overall, these tanks provide a safe way to dispose of the wastewater from a single household.
The Septic Tank Process
Curious about how the process works? The outlets normally divide the disposed of water into three compartments before it is excreted out of the system.
There are three layers that build in the septic tank once all the waste is entered into it. These three layers are namely:
This is the part that fills the tank. It’s basically watery waste.
Sludge comprises all the solids and the side results (by-products) of bacterial decomposition.
Scum is the top layer of fats, grease, and other oils.
Really, a septic tank looks like a settling pond because all the heavy solids sink to the bottom and the lighter insoluble items like oils and grease stick to the top.
The solids are separated from the water through filters and different chambers. The large portion is covered by water (known as the “affluent”) and the smaller chamber houses the solid waste.
There are drain holes in the tank that allow the water to reach the gravel. Solids are prevented by a filter from leaving the septic tank with the help of a filter.

Septic Tank Maintenance
Most septic tanks operate for years and their life length can be prolonged through proper maintenance such as septic tank pumping.
You need to get an annual check by a professional who will assess the condition of your septic tank and recommend treatment.
Keep the following things away from the drain in your house:
- Wipes and tissues
- Pads and tampons
- Cat litter
- Baby diapers
If a septic tank is not pumped regularly, it is possible for different items to stick in the filters, and eventually, this could lead to blocked chambers and clogging.
To avoid a septic tank repair that could cost thousands down the road, you need to make sure that you are following the guidelines of septic tank maintenance.
A frequently maintained septic tank can actually last for almost over 25 years, which is a huge lifespan so long as you take care of the septic system.
Thinking About Getting A Septic Tank?
Septic tanks are becoming extremely popular despite modern sewage systems. As many look to live in the countryside and escape the city, septic tanks will grow back in popularity.
If you are looking into a house with a septic tank, make sure you understand how they are designed, how they work, and where yours is located.
It’s always a good idea to get the tank pumped and inspected if you are interested in a particular property, or know the right questions to ask if you’re buying a house.
Good luck with that property and come to this blog for other construction and home renovation ideas and concepts!
What Is a Septic Tank Used For?
What Does a Septic Tank Do?
The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. Its job is to hold the wastewater long enough to allow solids to settle down to the bottom forming sludge, while the oil and grease floats to the top as scum.
How Much Is a Septic System?
If you are considering putting in a septic system, the cost ranges from $3,600 to $10,000 with an average cost for septic tank installation is $6,300. Although less common for average homeowners, specialized systems on the high end may cost upwards of $20,000.
Eco Friendly Septic Tank Design
The size of the septic tank should be based on the number of people using it and their daily water usage. An appropriately sized tank can minimize the need for frequent pumping and reduce the amount of waste that enters the drain field.
A septic tank is an underground chamber designed to treat wastewater from homes or buildings that are not connected to a public sewer system. It is a key component of a septic system, which typically includes pipes that carry wastewater from the building to the tank, a distribution box, and a drain field or leach field.
How Does a Septic Tank Work?
A septic tank is an underground system that is designed to treat and dispose of household wastewater. The tank is typically made of concrete, fiberglass, or plastic and is buried in the ground near the home. Here is how a septic tank works:
- Wastewater from the home flows into the septic tank through a pipe.
- The wastewater separates into three layers inside the tank. The top layer is scum, which is made up of oils, fats, and grease. The middle layer is liquid waste or effluent, and the bottom layer is solids or sludge.
How to Build Septic Tank in India?
- Determine the size and location of the septic tank: The size of the septic tank will depend on the number of bedrooms in the house and the estimated water usage. The septic tank should be located at least 5 meters away from the house and any water source.
- Excavate the site: Dig a hole in the ground for the septic tank. The depth of the hole will depend on the size of the tank. A typical septic tank in India is around 1.5 to 2 meters deep.
- Build the septic tank: The septic tank can be made of concrete, plastic, or fiberglass. Concrete is the most commonly used material in India. The walls of the septic tank should be at least 10 cm thick.
- Install inlet and outlet pipes: The inlet pipe should be connected to the main sewer line from the house. The outlet pipe should be connected to the drainfield.
Septic Tank Design 3 Chambers
- Inlet Chamber: The first chamber is the inlet chamber, where wastewater enters the septic tank through the inlet pipe. This chamber is designed to separate solids and liquids.
- Middle Chamber: The middle chamber is where the liquid waste (effluent) is further treated. The effluent flows through an opening in the dividing wall between the first and second chambers.
- Third Chamber: The third chamber is the final stage of treatment. It is where any remaining solids and scum are further broken down and treated by bacteria. The effluent is then discharged into the drainfield or leachfield.
Septic Tank for Apartments
In general, a septic tank for an apartment building will need to be larger than one for a single-family home because it will be handling more wastewater. The size of the septic tank will need to be determined based on the estimated daily water usage of the building. It is also important to consider the soil type and site conditions where the septic tank will be installed.
Septic Tank Construction Step by Step
- Obtain necessary permits: Check with your local health department or other relevant agencies to obtain any necessary permits and ensure that you comply with local regulations.
- Plan the design: Determine the size and location of the septic tank based on the number of bedrooms in your home and the soil type. A professional engineer or contractor can assist you in this process.
- Excavate the site: The excavation process will involve removing the topsoil and digging a hole that is deep enough to accommodate the septic tank.
- Install the inlet and outlet pipes: The inlet pipe should be placed in a position that allows for proper flow of wastewater into the tank. The outlet pipe should be positioned so that it connects to the drain field.
Details of Septic Tank
A septic tank is an underground wastewater treatment system that is commonly used in areas that do not have access to a centralized sewer system. It consists of a large tank that is designed to hold and treat household wastewater, including sewage, greywater, and other organic matter.

Eco Friendly Septic Tank Design
Designing an eco-friendly septic tank can help reduce the environmental impact of human waste disposal. Here are some design considerations for an eco-friendly septic tank:
- Size: The size of the septic tank should be determined based on the number of people using it, and the daily water usage. A larger tank may be needed for larger households or high water usage.
- Location: The septic tank should be located away from wells, streams, or other water sources to prevent contamination. It should also be accessible for regular maintenance and pumping.
