When the grading of the septic system does not allow for proper drainage, it is crucial to adjust the grading to ensure effective drainage. Proper grading is essential in a septic system to facilitate the movement of effluent away from the system and to prevent pooling or flooding, which can lead to system failure and environmental contamination.
Adjusting the grading helps to direct water flow away from the septic tank and drainage field, thereby promoting adequate drainage and maintaining the integrity and functionality of the system. This adjustment might involve regrading the surface to create a slope that encourages water to move away rather than stagnate, which is critical for the absorption of wastewater into the surrounding soil.
Neglecting to take action—such as not adjusting the grading or simply filling with more soil—can lead to serious complications, including system backups, health hazards from septic leaks, or damage to surrounding property. Monitoring the situation without making necessary adjustments is also insufficient, as it does not address the root problem that could worsen over time.
