When it comes to treating wastewater, the septic system you choose plays a critical role. It must meet the needs of your property while also adhering to local regulations. To aid in your decision-making process, let's explore the different types of septic systems available.
1. Conventional Septic Systems
Conventional septic systems are the most common type, especially in rural areas. These systems consist of two main components: a septic tank and a soil absorption field, also known as a drainfield or leachfield. The tank holds wastewater from your home, allowing solids to settle, while the drainfield treats the liquid effluent using natural soil processes.
Conventional systems further divide into two categories:
Gravity Systems: As the name implies, these systems rely on gravity to move effluent from the tank to the drainfield. They're simple, reliable, and low-maintenance but require a specific slope and enough vertical distance between the drainfield and the water table or bedrock.
Pressure Distribution Systems: These systems use a pump to distribute effluent evenly across the drainfield. They're typically used when the water table or bedrock is near the soil surface or when the property lacks the necessary slope for a gravity system.
2. Chamber Systems
Chamber septic systems are a variation of the conventional system, using chambers instead of a traditional drainfield. The chambers, made of durable material like plastic or concrete, create an empty space where effluent can be stored before it percolates into the surrounding soil. These systems are often chosen for their ease of installation and their ability to handle heavy or sporadic usage.
3. Drip Distribution Systems
Drip distribution systems, or drip irrigation systems, use a series of small-diameter pipes to distribute effluent slowly and evenly across the drainfield. They're often used in areas with shallow soil over bedrock or a high water table. These systems require a pump and a series of filters to ensure that the small pipe openings don't get clogged.
4. Aerobic Treatment Units (ATUs)
ATUs introduce air into the wastewater to enhance the activity of aerobic bacteria, which break down waste more effectively than their anaerobic counterparts in a conventional septic tank. The treated effluent is then released into the drainfield. ATUs are often used in environmentally sensitive areas or properties with small lots.
5. Mound Systems
Mound systems are a solution for properties with shallow soil over porous bedrock or a high water table. They involve placing a mound of sandy soil above the natural soil surface. The effluent is pumped into the mound, where it's treated as it percolates through the sand and into the natural soil.
6. Constructed Wetland Systems
These systems mimic natural wetland processes to treat wastewater. They direct effluent into a human-made wetland area where plants, microbes, and sunlight work to purify the water. They're used in rural or low-population areas and require a significant amount of land.
Choosing the right septic system involves considering your property's specific conditions, local regulations, and your budget. Consult with a septic system professional, like GreenPro in Mississippi, to ensure you select the most suitable system for your needs. By understanding the variety of options available, you can make an informed decision and ensure your home has a reliable and efficient wastewater treatment system.
