On-Site Sewage Facilities (OSSFs) are systems designed to treat and dispose of wastewater from homes or businesses that are not connected to a centralized sewer system. These facilities typically include components like septic tanks and drain fields, which work together to break down and filter waste before it is released into the environment. OSSFs are essential in rural or remote areas where municipal sewage services are unavailable. Proper maintenance and regular inspections are crucial to ensure these systems function effectively and do not pose a risk to public health or the environment.
