How Do Septic Tanks Work

What is the Function of a Septic Tank?

A septic tank is an underground container made of fibreglass, concrete or polyethene plastic. It’s an integral part of the septic system, responsible for the smooth functioning of daily activities. It’s a significant part of the waste removal system designed to treat wastewater. However, poor maintenance can affect the functioning of a septic tank, causing system breakdown. Consulting with an expert in septic pumping in Auburn is necessary to maintain its functioning.

The Function of a Septic Tank ▪ Decomposition Septic tanks collect wastewater from the house and treat it with aerobic bacteria solidifying scum.

▪ Drainage The wastewater releases into the drain field, where aerobic bacteria further treat it before releasing it into the soil for other purposes.

How Do Septic Tanks Work?

1. A septic tank collects wastewater and solid waste from the house.

2. Anaerobic bacteria treat wastewater and solid waste by breaking them down.

3. Solid waste or inorganic waste sinks to the bottom, and liquid waste, such as oils, fats, and grease rises 4. The wastewater drains into the drain field, where aerobic bacteria treat it for further means.

5. The filtered or treated water drains into the soil through a distribution box.

Poor maintenance affects the smooth functioning of a septic tank, causing backups in the house.

Backups and clogged pipes lead to expensive repairs and replacements. According to Environmental Protection Agency (EPA), homeowners should do septic pumping every three to five years. Regular pumping eliminates sludge and scum, keeping your septic system healthy and running.

A Septic Tank Has the Following Three Layers   

The top layer contains fats called scum, which floats above.

The middle layer contains clear liquid waste called effluent.

The bottom layer contains solid waste that forms sludge, which sinks.

Tips for Maintaining a Septic Tank 1. Stop flushing unwanted items down the drain, such as cigarette butts, coffee grounds, and diapers.

2. Synthetic fibres cause lint flows to the septic tank, causing problems because bacteria cannot break it down.

3. Using harsh chemicals like disinfectant cleaners and antibacterial soaps can kill the bacteria in the septic tank.

4. Draining too much water down the drain over a short time period can strain the septic tank.

5. Installing a septic system near trees can cause problems because tree roots can infiltrate the system and clog the drain field.

Importance of Septic Tanks   

Septic tanks treat sewage waste before releasing it into the environment.

Septic tanks allow treated water to be used for different purposes, such as industrial works, irrigation, groundwater recharge etc.

Septic tanks ensure the smooth functioning of the house’s plumbing system.

Conclusion A septic tank is an underground sedimentation container that treats wastewater with the help of biological decomposition and drainage. Regular maintenance is required to keep your septic system working smoothly. Healthy maintenance starts with the understanding of septic tank functioning.
