What does the term "expansion" refer to in the context of sewage systems?

In the context of sewage systems, the term "expansion" specifically refers to a change in a facility that increases the sewage volume beyond the original design. This can happen for various reasons, such as population growth, increased industrial activity, or additional services and amenities being added to a building or facility. When a facility’s capacity is exceeded, it may require an upgrade or expansion of the sewage system to manage the increased flow effectively.

Understanding this concept is crucial for septic installers because recognizing when a system requires expansion is essential to maintain proper wastewater management and prevent system overloads or failures. This ensures that the system continues to operate efficiently while adhering to environmental regulations and public health standards.
