Understanding Septic Systems
A septic system is an on-site wastewater treatment system commonly used in rural and suburban areas where centralised sewer systems are not available. It consists of a septic tank and a drainfield, working together to treat and dispose of household wastewater.
When wastewater from your sinks, toilets, and other drains enters the septic tank, solids settle to the bottom, and oils and greases float to the top. The liquid effluent in the middle layer flows out of the tank into the drainfield, where it undergoes further treatment by the soil.
Types of septic systems
1. Conventional gravity system
The conventional gravity septic system relies on gravity to transport wastewater from the home into the septic tank and then to the drainfield. This type of system is suitable for properties with sufficient soil depth and permeability.
2. Pressure distribution system
Pressure distribution septic systems use a pump to evenly distribute the effluent from the septic tank into the drainfield. This ensures a more controlled and uniform distribution of wastewater, making it ideal for properties with varying soil conditions.
3. Aerobic treatment unit (ATU)
ATU septic systems incorporate an aerobic treatment process to break down and treat wastewater more efficiently. These systems use oxygen to encourage the growth of beneficial bacteria, resulting in cleaner effluent. ATUs are well-suited for properties with limited space or poor soil quality.
4. Mound system
Mound septic systems are designed for properties with high groundwater levels or poor soil percolation. They involve building an elevated drainfield, or mound, to ensure adequate treatment and filtration of wastewater before it enters the natural soil.
Factors to consider when choosing a septic system
Selecting the right septic system for your property involves careful consideration of several factors, including:
1. Soil conditions
Evaluate the soil type and permeability on your property. Certain systems may not be suitable for clayey or poorly draining soils.
2. Property size and layout
Consider the size and layout of your property to determine the appropriate location for the septic tank and drainfield. Ensure compliance with local setback regulations.
3. Water usage
Take into account your household’s water usage patterns when sizing the septic tank. A larger tank may be necessary for larger households or those with high water consumption.
4. Environmental impact
Opt for septic systems that promote environmental sustainability and minimize groundwater contamination.
Septic system installation and maintenance
Proper installation and regular maintenance are crucial for the efficient and long-lasting performance of your septic system. We strongly advise hiring a professional plumbing service to handle the installation to ensure compliance with local codes and regulations.
Routine maintenance tasks include:
- Regularly pumping the septic tank to remove accumulated solids.
- Checking and maintaining the integrity of the drainfield to prevent clogging.
- Avoiding the flushing of non-biodegradable items or harmful chemicals into the septic system.
