Why septic systems fail?

1. Hydraulic overload: Too much water, too fast. Marathon laundry days, long showers, or a running toilet can drown the field.
2. Neglected pumping: Sludge and grease escape the tank and plug soil pores, thickening the biomat.
3. Compaction: Parking, patios, or heavy storage over the field crush the soil structure.
4. Roots: Trees love nutrient-rich moisture roots invade and block lines.
5. Poor siting/design: High groundwater, tight clay soils, or undersized fields limit capacity from day one.
6. Chemical shocks: Dumping solvents or lots of disinfectants can knock out the microbes that do the real work.
