What should be done to abandoned treatment units?

Abandoned treatment units must be crumbled and filled with sand or soil to ensure both safety and environmental protection. When a treatment system is no longer in use, simply leaving it intact or covering it with dirt can lead to potential hazards, such as accidental injuries or groundwater contamination. Crumbling the unit allows for proper sealing and prevents any remaining waste materials from leaking into the surrounding environment. Filling the unit with sand or soil also helps to stabilize the area, reducing any risk of surface collapse and making the site safer for future use or development. This method aligns with regulatory practices aimed at maintaining environmental health standards and preventing public health risks associated with abandoned wastewater treatment systems.
