What can happen if a septic system is overloaded?

When a septic system is overloaded, it can lead to backups and system failure due to exceeding the design capacity of the system. A septic system is engineered to handle a certain volume of wastewater and treat it properly. When more waste is introduced than the system can manage, the wastewater may not be adequately processed. This can cause sewage to back up into the home or surface in the yard, creating health hazards and environmental contamination.

Overloading can disrupt the balance of bacteria necessary for the natural decomposition of waste, leading to longer-lasting solids in the tank and eventually clogging the system. This scenario necessitates costly repairs or even a complete replacement of the septic system, underscoring the importance of adhering to recommended usage and maintenance practices to ensure system longevity and functionality.
