How should a newly installed OSSF be marked for visibility?

Marking a newly installed On-Site Sewage Facility (OSSF) with durable markers for the tank and drain field locations is essential for several reasons. Primarily, it ensures that the positions of the components are clearly identified, reducing the risk of accidental damage during landscaping, construction, or any maintenance activities in the area. Durable markers can withstand environmental elements and remain visible over time, helping to inform property owners, maintenance personnel, or any contractors about the system's layout.

In contrast, using temporary flags may not provide reliable long-term visibility, as they can easily be removed or deteriorate over time. Paint on the ground might also fade, wear off, or become obscured due to landscaping or weather, compromising the visibility that is crucial for safe and effective maintenance. Not marking the system at all is highly discouraged, as it significantly increases the risk of unintentional disturbances that could lead to costly repairs or environmental issues. Therefore, employing durable markers is the most effective and responsible approach to ensure ongoing awareness and protection of the OSSF components.
