What issue can arise from localized distribution in a gravity flow system?

Localized distribution in a gravity flow system can lead to overloading of infiltrative surfaces. In such systems, if wastewater is not evenly distributed, certain areas may receive a disproportionate amount of effluent. This can saturate those specific infiltrative surfaces faster than they can process the wastewater, leading to a situation where the soil is unable to adequately treat the effluent, ultimately causing backups or system failures.

The expertise in septic system design emphasizes the necessity of balanced distribution to prevent any particular area from becoming overwhelmed, thus ensuring efficient treatment and minimizing potential environmental impacts. When effluent is concentrated in one area, the natural treatment processes that occur in the soil may become compromised, leading to potential contamination issues or system breakdowns. This highlights the importance of proper design and maintenance in septic systems to avoid overloads and ensure the overall functionality of the system.
