How far must it be between each trench?

The requirement for maintaining a distance between each trench in a private sewage system relates to ensuring proper function and minimizing the risk of contamination or failure in the sewage disposal system. In Illinois, the standard distance that must be maintained between each trench is six feet. This spacing allows for adequate separation between different areas of effluent absorption, ensuring that one trench does not adversely affect another. This distance helps maintain soil integrity and promotes effective drainage and treatment of sewage, which is essential for protecting public health and the environment.

By adhering to this guideline, contractors can ensure that the sewage treatment system operates efficiently, minimizing the chances of system overload or failure while also safeguarding groundwater and surrounding areas from potential contamination.
