What happens when an OSSF system is overloaded with water?

When an On-Site Sewage Facility (OSSF) system is overloaded with water, it can lead to system failure due to several factors. An overloaded system experiences excessive hydraulic load, which can overwhelm the system's design capacity. This may cause a variety of issues, such as reduced treatment efficiency, increased risk of backups, and potential discharge of untreated wastewater into the environment.

The system relies on a balanced process to treat the wastewater effectively, and when too much water is introduced, it disrupts the biological and physical processes essential for breaking down contaminants. The treatment components, such as the tank, drain field, and any filtration systems, may become saturated, leading to improper treatment and potential environmental harm. In severe cases, this overload can damage the infrastructure, require costly repairs, and lead to violations of health and environmental regulations.

Understanding the capacity and limitations of an OSSF system is crucial for maintaining its integrity and ensuring its effective operation. This is why managing water input is essential for preventing overload and maintaining system functionality.
