DIY Septic Tank Treatment: Effective Home Remedies

Living in a rural area or a home not connected to a municipal sewer system typically means having a septic system. These systems are such an important aspect of country living, yet many homeowners lack a full understanding of their functionality and maintenance requirements.

This comprehensive guide will delve into the essentials of septic systems, including their purpose, operational principles, and vital maintenance tips to forestall expensive repairs.

Understanding Septic Systems: The Role in Aerobic and Anaerobic Processes

A septic system is a crucial component of many residential and rural properties, responsible for the treatment and disposal of wastewater. It operates by harnessing the power of two distinct biological processes: aerobic and anaerobic. These processes play a central role in the efficient breakdown of waste materials within the system, ensuring the safe and eco-friendly management of wastewater. First, lets discuss the differences between aerobic and anaerobic systems and highlight the essential role a septic holding tank plays in both.

The Anatomy of a Septic System

A typical septic system consists of three primary parts:

1. Septic Tank: Usually constructed from materials like concrete, fiberglass, or plastic, a septic tank is the initial receptacle where incoming wastewater from your home is collected. Concrete septic tanks are favored for their durability and longevity.
2. Drain Field: The drain field, also known as the leach field, is the area where treated effluent is dispersed into the surrounding soil. This critical component acts as a natural filtration system.
3. Soil: The soil in the drain field plays a pivotal role in the final treatment of wastewater. It acts as a biological filter, further purifying the effluent before it eventually merges with groundwater.

Aerobic vs. Anaerobic Processes

The primary difference between aerobic and anaerobic septic systems lies in the conditions under which bacteria and other microorganisms break down organic matter. The choice between them largely depends on factors such as local regulations, soil conditions, and maintenance preferences.

1. Aerobic Septic System:

In an aerobic septic system, oxygen is intentionally introduced into the septic tank. This oxygen-rich environment promotes the growth of aerobic bacteria, which require oxygen to thrive. These bacteria are highly effective at breaking down organic materials in wastewater.

Key Features of Aerobic Systems:

• Aeration: Aerobic systems incorporate mechanical or natural aeration methods to infuse oxygen into the tank.
• Efficiency: Aerobic systems are generally more efficient in breaking down waste and producing cleaner effluent.
• Maintenance: They tend to require more maintenance due to the need to monitor and maintain the aeration equipment.

2. Anaerobic Septic System:

Anaerobic septic systems, on the other hand, create an oxygen-deprived environment within the septic tank. This environment encourages the growth of anaerobic bacteria, which can survive without oxygen but are less efficient at breaking down waste compared to their aerobic counterparts.

Key Features of Anaerobic Systems:

• No Aeration: Anaerobic systems do not require aeration equipment and are generally simpler in design.
• Efficiency: They are less efficient in breaking down waste and may produce effluent that requires additional treatment.
• Maintenance: Anaerobic systems are typically easier to maintain due to their simplicity, but the effluent quality may be lower.

The Central Role of the Septic Holding Tank

Regardless of whether a septic system is aerobic or anaerobic, the septic holding tank serves as the initial stage of wastewater treatment. Here's how it operates:

a. Wastewater Segregation: Incoming wastewater is stratified into three distinct layers within the septic tank:

• Scum: This top layer comprises lighter substances, such as oils and grease, which float on the surface.
• Effluent: The middle layer is the liquid effluent, which is relatively clear and contains suspended particles.
• Sludge: The heaviest solids settle at the bottom, forming the sludge layer.

b. Biological Processes: Within the tank, both aerobic and anaerobic bacteria begin breaking down the organic matter in the scum, effluent, and sludge layers.

c. Effluent Discharge: The partially treated effluent is then expelled from the septic tank into the drain field, where it percolates through the soil. The soil's natural filtration and microbial activity further purify the effluent before it ultimately rejoins the groundwater.

What Size Of Tank Do I Need?

The size of your tank is contingent on your home's size. An average residence usually requires a 1000 gallon septic tank, but larger homes might need bigger capacities. For specific sizing, a septic inspection by a professional can provide accurate guidance.

Proactive Septic Maintenance

Proper maintenance and regular inspection of your tank ensure its longevity and eco-friendly operation, benefiting both your household and the environment.

• Regular Pumping: Pumping every 3-5 years, depending on usage and tank size, is essential. This is particularly true for tanks like a 1000 gallon concrete septic tank, which require diligent maintenance. For comparison, a 500 gallon septic tank would require pumping more frequently, while a 1500 gallon septic tank would require less.
• Careful Flushing Habits: Avoid flushing anything other than human waste and toilet paper. Items like wipes and harsh chemicals can damage the system.
• Water Conservation: Excessive water use can overwhelm your tank. Simple measures like fixing leaks can significantly reduce the risk of septic backup.
• Drain Field Vigilance: Regularly inspect your drain field for warning signs like standing water or strong odors. Heavier solutions, such as an above ground septic tank, might be required in certain situations.
• Concrete septic tank lids and septic tank filters should be inspected and updated as needed.

• Addressing Smells: Mixtures of baking soda and vinegar can mitigate odors, as can septic bacteria additives, which enhance waste breakdown and odor control.
• Resolving Blockages: Use a plunger for minor clogs, avoiding chemical cleaners that harm septic systems. Persistent blockages might require professional intervention.
• Reducing Pumping Frequency: Water conservation and avoiding flushing non-biodegradable items can lessen the need for frequent septic pumping.

Indicators of Tank Failure

A tank that is not properly maintained can lead to costly repairs and even health hazards. Be vigilant for signs of a failing septic system, such as slow draining fixtures, unpleasant odors, sewage backup, unusually verdant grass near the drain field, or visible septic overflow. These symptoms necessitate immediate attention from a professional for septic repair or service if home remedies described in the previous section are not adequate. A portable septic tank can provide temporary waste management if repairs are expected to take time or in areas where permanent tanks are not feasible.

Conclusion

Septic systems are an essential part of a home's plumbing system, and proper maintenance is key to avoiding costly repairs and health hazards. By understanding how septic tanks work and following these maintenance tips, you can ensure your tank functions properly and avoid any major issues. If you notice any signs of a failing tank, be sure to contact a professional for assistance.
