What should be assessed during a site evaluation for OSSF?

During a site evaluation for an On-Site Sewage Facility (OSSF), it is crucial to assess multiple factors that directly affect the functioning and safety of the system. This includes soil type, which influences drainage and filtration; the slope of the land, which can impact how water flows and prevents flooding; depth to the water table, to ensure that the OSSF does not contaminate groundwater; and proximity to waterways, as this helps protect water quality in nearby lakes and rivers.

Understanding these elements is essential for proper system design that will allow for effective treatment of wastewater, minimization of environmental impact, and prevention of public health hazards. Each of these factors plays a vital role in determining whether a site is suitable for an OSSF and informs the design and management of the system to ensure long-term functionality and compliance with local regulations.
