Springfield and surrounding Greene and Christian County communities continue to grow, and not every home is connected to a municipal sewer line. For many suburban and rural households, septic systems effectively handle wastewater treatment. While all septic systems serve the same purpose, the way they process and clean wastewater can differ significantly. In Springfield, the three most common systems are conventional septic systems, chamber systems, and aerobic treatment units (ATUs).
Understanding how each system functions helps homeowners protect their investment and avoid costly repairs. From family homes in Battlefield and Nixa to rural properties outside Republic and Rogersville, and to expanding neighborhoods on the outskirts of Springfield, each septic system requires specific care. Mr. Rooter Plumbing of Springfield specializes in keeping them all working reliably.
Conventional Septic Systems
Conventional septic systems are the oldest and most widely used design, valued for their simplicity and reliability. These systems are made of a septic tank and a drain field.
When wastewater leaves the home, it flows into the septic tank. Inside the tank, waste separates into three layers: solids settle to the bottom as sludge, oils and fats float to the top as scum, and the liquid effluent remains in the middle. Baffles and effluent filters regulate this process, ensuring that solids and scum stay in the tank while the effluent flows out.
Anaerobic bacteria inside the tank digest some of the waste, reducing sludge buildup. The effluent then moves into the drain field, which consists of perforated pipes buried in gravel trenches. As the liquid filters through the gravel and surrounding soil, harmful bacteria and nutrients are removed. By the time it reaches the groundwater, it has undergone a natural cleaning process.
Conventional systems are highly effective when soil conditions are favorable. Springfield’s surrounding areas, with their mix of clay and loam soils, sometimes challenge effluent absorption. If soil is too dense or shallow, drainage slows and the system’s efficiency drops. Despite these challenges, conventional systems remain popular for suburban and rural homes with adequate lot space.
Maintenance is straightforward but essential. Tanks should be pumped every three to five years to prevent solids from entering the drain field. Annual inspections of baffles, filters, and soil absorption performance help prevent failures. When properly maintained, conventional systems can last for decades.
Chamber Septic Systems
Chamber septic systems were developed as an alternative to gravel drain fields. Instead of using gravel-filled trenches, chamber systems employ open-bottom plastic chambers. Effluent flows from the septic tank into these chambers and then gradually seeps into the surrounding soil.
The chamber design increases the contact area between wastewater and soil, encouraging natural filtration and microbial activity. By eliminating the need for gravel, chamber systems simplify installation, making them cost-effective in areas where gravel is expensive or complicated to transport. They are remarkably adaptable to Springfield’s outskirts, where residential developments may feature smaller lots or irregular soil conditions.
One of the strengths of chamber systems is their ability to handle fluctuating water use. The chambers provide temporary storage space, which allows effluent to be absorbed gradually instead of all at once. This makes them suitable for larger families or properties where water use varies day to day.
Like conventional systems, chamber designs depend heavily on soil absorption. In neighborhoods where soil is dense or compacted, the chambers may struggle to keep up with effluent flow. Over time, poor drainage can lead to wastewater pooling, unpleasant odors, or system failure.
Maintenance requirements remain broadly similar to those of conventional systems. Tanks must be pumped every three to five years, and chambers should be inspected regularly to confirm they are intact and functioning correctly. Effluent filters and tank baffles also play a crucial role in protecting the chambers from solids. Mr. Rooter Plumbing of Springfield provides inspections, pumping, and repairs explicitly designed for chamber systems.
Aerobic Treatment Units (ATUs)
Aerobic treatment units are the most advanced of the three common septic system types, functioning more like miniature wastewater treatment plants. They introduce oxygen into the treatment process, which accelerates waste breakdown and produces cleaner effluent than conventional or chamber systems.
The process begins in a pretreatment tank where solids settle and scum floats, similar to a conventional septic tank. From there, effluent moves into an aeration chamber. This chamber utilizes pumps or blowers to continuously inject air into the water, thereby creating an oxygen-rich environment. Aerobic bacteria thrive under these conditions and digest waste much more effectively than anaerobic bacteria.
After aeration, the liquid passes into a clarification chamber where remaining solids settle. Some systems recycle these solids back into the aeration chamber for further treatment. Many ATUs also include a disinfection step, often with chlorine tablets or UV light, to eliminate any remaining pathogens. The treated water is then released into a small drain field, drip irrigation system, or surface spray area.
Because they produce cleaner effluent, ATUs are often installed where soil conditions or property sizes prevent the use of conventional systems. In Springfield, this can include suburban neighborhoods with smaller lots, areas with dense clay soils, or properties near streams and waterways where environmental protection is critical.
ATUs are effective but require more frequent and detailed maintenance. Pumps, blowers, and alarms must be inspected every six to twelve months to maintain proper operation. The tank still requires pumping every two to three years, and the disinfection system needs consistent upkeep. Without this care, ATUs can fail quickly. Mr. Rooter Plumbing of Springfield offers scheduled maintenance plans for aerobic systems, ensuring they continue to meet performance and environmental standards.
Common Issues Across Septic Systems
While designs differ, all septic systems are vulnerable to similar problems. One of the most frequent issues in Springfield is system overloading. Larger households or properties that use a significant amount of water can discharge more effluent into the tank and drain field than the system was designed to handle. This can force solids out of the tank and into the soil, clogging the drain field.
Clogs caused by non-biodegradable items are another concern. Items such as wipes, paper towels, feminine hygiene products, and grease do not break down and can cause premature system failure. Tree roots are also a problem in Springfield’s suburban neighborhoods, as they can infiltrate pipes and disrupt system performance.
Drain field failure is one of the most expensive issues homeowners face. If soil becomes compacted or oversaturated, effluent cannot filter properly. The result is pooling water, unpleasant odors, and potential contamination of groundwater. Preventing this issue requires consistent pumping and careful monitoring of water use.
Neglect remains the leading cause of septic system problems. Because septic systems are often buried and easily overlooked, maintenance can be easily overlooked. Mr. Rooter Plumbing of Springfield recommends regular pumping and inspections to avoid costly emergencies.
Choosing the Right Septic System in Springfield
The best septic system for a property depends on soil conditions, lot size, household water usage, and local environmental requirements. Conventional systems are reliable and cost-effective when the soil is favorable and lot sizes are large enough for a drain field. Chamber systems are better suited for smaller lots or areas where gravel is impractical. Aerobic treatment units are often chosen for challenging soil conditions, smaller properties, or environmentally sensitive areas.
For Springfield homeowners, the decision often comes down to balancing cost with performance. Families in suburban neighborhoods may find chamber systems ideal, while homes near waterways or on smaller lots may require aerobic treatment. Mr. Rooter Plumbing of Springfield provides property evaluations and system recommendations to ensure every installation is the right fit.
