Understanding the Working of Septic Tank and Unlocking the Secrets to Efficient Fecal Sludge Management

June 22, 2023



Septic tanks are an integral part of many residential and commercial properties, serving as an on-site sewage treatment system. They play a crucial role in safely managing and disposing of human waste and other organic matter. Understanding the workings of septic tanks is essential for maintaining their functionality and avoiding costly repairs. A septic tank is an underground wastewater treatment system commonly used in areas without access to centralized sewer systems. It consists of several key components that work together to effectively treat and dispose of human waste and other organic matter. It is typically made of concrete, fibreglass, or plastic and is divided into two compartments. Let’s start by understanding the essential components of a septic tank.
  1. Inlet Pipe: The inlet pipe connects the septic tank to the building’s plumbing system, allowing wastewater to enter the tank for treatment. It is important to ensure that only wastewater flows into the tank and that solid waste and excessive water from sources such as rain are kept out.
  2. Septic Tank: A septic tank is a watertight container composed of fibreglass, plastic, or concrete. It acts as a primary treatment unit where solid waste settles at the bottom, and oils and grease float to the top. The tank is designed to allow the wastewater to flow through, promoting the separation of solids and liquids.
  3. Baffles: Baffles are partitions within the septic tank that help regulate the flow of wastewater. They prevent the immediate discharge of floating solids and scum into the drain field, allowing time for the solid waste to settle at the bottom and form a layer called sludge.
  4. Outlet Pipe: The outlet pipe connects the septic tank to the drainfield, where further treatment of the effluent takes place. The outlet pipe is positioned near the top of the tank, ensuring that only the clarified liquid, known as effluent, flows out. It is crucial to maintain a clear outlet pipe to prevent any blockages or backups.
  5. Drain Field: The drain field consists of a network of perforated pipes or trenches buried in gravel or sand. It allows the effluent to percolate through the soil, where further treatment and filtration take place before it reaches the groundwater.
Processes in a Septic Tank:
  1. Separation: When wastewater enters the septic tank, it undergoes a natural separation process. Oils and fats float to the top, making a layer of scum, while solid waste settles to the bottom to produce a layer of sludge. The middle layer consists of partially clarified wastewater.
  2. Digestion: The sludge layer at the bottom of the tank undergoes a process called anaerobic digestion. Naturally occurring bacteria and enzymes break down the organic matter, converting it into simpler substances.
  3. Filtration: The partially clarified wastewater in the middle layer flows through the outlet pipe into the drain field. A network of perforated pipes buried in trenches filled with gravel makes up the drain field. As the effluent percolates through the soil, it undergoes further filtration and purification, removing harmful pathogens and pollutants.
