What is the minimum horizontal distance between a sanitary sewage system and any basement?

The minimum horizontal distance between a sanitary sewage system and any basement is typically established to prevent potential contamination and to ensure the integrity of the sewage system. A distance of 15 feet is recommended to allow for safe integration of sewage infrastructure while reducing the risk of sewer gas infiltrating the basement space.

This standard helps mitigate risks associated with odor and potential health hazards from sewage leaks, which could occur if a sewer line were too close to living spaces, particularly basements where there is often less ventilation. Additionally, adhering to this distance helps in the maintenance of both the sewage system and the structural safety of the building. This guideline emphasizes the importance of maintaining safe separation between the sewage system and residential structures to protect human health and property.
