What is a septic tank and how does it work in gravity systems?

Step Action Novel Insight Risk Factors
1 Inlet pipe The septic tank receives wastewater from the house through the inlet pipe. The inlet pipe should be properly installed and maintained to prevent blockages and leaks.
2 Solids settling chamber The solids in the wastewater settle at the bottom of the tank, forming a sludge layer, while the lighter materials, such as grease and oils, float to the top, forming a scum layer. The solids settling chamber should be regularly pumped to prevent the accumulation of sludge and scum, which can cause blockages and overflow.
3 Baffle The baffle separates the solids settling chamber from the outlet pipe, allowing only the clear liquid, or effluent, to flow out of the tank. The baffle should be properly installed and maintained to prevent clogs and leaks.
4 Anaerobic bacteria The effluent flows into the drain field, where it is treated by anaerobic bacteria in the soil, which break down and remove harmful pathogens and pollutants. The drain field should be properly sized and located to prevent contamination of nearby water sources and to ensure proper treatment of the effluent.
5 Distribution box The distribution box evenly distributes the effluent to the soil absorption system, which consists of a network of perforated pipes buried in the soil. The distribution box should be properly installed and maintained to ensure even distribution of the effluent and to prevent clogs and leaks.
6 Soil absorption system The effluent is absorbed by the soil, where it is further treated by aerobic bacteria, which break down and remove any remaining pollutants. The soil absorption system should be properly sized and located to prevent contamination of nearby water sources and to ensure proper treatment of the effluent.
7 Percolation test Before installing a septic system, a percolation test should be conducted to determine the soil’s ability to absorb and treat the effluent. A failed percolation test may indicate that the soil is not suitable for a septic system, which could result in costly repairs or the need for an alternative wastewater treatment system.
8 Grease trap A grease trap should be installed in the kitchen to prevent grease and oils from entering the septic system, which can cause clogs and overflow. The grease trap should be regularly cleaned and maintained to prevent blockages and odors.
9 Treatment process A septic system is a natural and effective way to treat wastewater, but it requires proper installation, maintenance, and monitoring to ensure its continued effectiveness. Neglecting to properly maintain a septic system can result in costly repairs, environmental damage, and health hazards.

Common Mistakes And Misconceptions

Mistake/Misconception Correct Viewpoint
Gravity systems are always better than pump systems. The choice between gravity and pump septic systems depends on various factors such as the site’s topography, soil type, water table level, and household size. In some cases, a gravity system may not be feasible or practical due to these factors.
Pump systems require more maintenance than gravity systems. Both types of septic systems require regular maintenance to function properly. However, pump systems may need more frequent inspections and pumping because they rely on mechanical components that can malfunction or wear out over time.
Pumping wastewater uphill is impossible with a gravity system. While it’s true that a gravity system relies on natural slope or elevation changes to move wastewater from the house to the septic tank and then to the drain field, there are ways to overcome minor elevation differences using lift stations or other techniques without resorting to a pump system entirely.
Gravity systems are cheaper than pump systems in all cases. The cost of installing either type of septic system depends on several variables such as local regulations, labor costs, materials used, site conditions (e.g., rocky terrain), etc., so it’s difficult to make generalizations about which one is cheaper overall without considering specific circumstances for each case individually.
