BLOG Understanding the Science Behind Septic Systems: Insights from Manny's Experts Mar 22, 2025

When it comes to septic systems, many homeowners often think of them as mysterious underground units that silently manage waste. However, understanding the science behind these systems can be incredibly beneficial. Not only does it empower you to troubleshoot minor issues, but it also helps in making informed decisions about maintenance and repairs. At Manny's Septic Repair, we believe that informed customers are happy customers, which is why we’re here to share our insights into the science of septic systems.

A typical septic system comprises two main components: the septic tank and the drainfield. The septic tank acts as a primary treatment facility, receiving wastewater from your household. It's a buried, watertight container made of concrete, fiberglass, or polyethylene. The science here lies in the separation process. Solid waste settles at the bottom forming sludge, while oils and grease float to the top as scum. The middle layer, consisting of partially clarified water, flows out to the drainfield.

The drainfield, also known as the leach field, is where the secondary treatment occurs. Here, the water gets further purified as it percolates through the soil, which acts as a natural filter. The soil's bacteria break down any remaining organic waste, harmful bacteria, and nutrients. Understanding this process emphasizes the importance of maintaining the soil's condition and avoiding compaction by heavy machinery or vehicles.

Regular maintenance of your septic system is crucial to its longevity and efficiency. At Manny's Septic Repair, we recommend pumping your tank every three to five years, depending on household size and tank capacity. Regular inspections are also key to catching potential issues before they become major problems. During an inspection, our experts check for proper system operation, look for signs of leaks, and ensure the tank isn’t overfilled. Keeping accurate records of maintenance can help and provide valuable information to future homeowners.

Common signs that your septic system may not be working efficiently include slow drains, sewage backup, and unpleasant odors. Also, puddling water or lush green patches near the drainfield can indicate a saturated drainfield or a leak. If you notice any of these issues, contacting professionals like those at Manny's Septic Repair promptly can prevent more costly damage and protect your property’s value.

For environmentally-conscious homeowners, understanding the impact of household products on their septic systems is essential. Excessive use of bleach, antibacterial soaps, and harsh chemicals can disrupt the beneficial bacteria essential for septic tank processes. By opting for septic-safe products and conserving water usage, you can greatly extend your septic system’s life.
