Which characteristic is essential for alternative infiltration trench products?

For alternative infiltration trench products, meeting approval and equivalency standards is essential because these products must be demonstrated to effectively manage wastewater in a manner that is safe and reliable. Approval from relevant regulatory bodies ensures that the products have been tested and deemed suitable for specific onsite wastewater applications, confirming that they offer equivalent performance to traditional materials and systems. This is vital to ensure public health and environmental safety as well as compliance with local regulations.

While other characteristics, such as capacity enhancements or availability in local markets, may be beneficial, they do not carry the same weight regarding the necessary validation and approval standards. Using traditional materials could be a preference but is not a strict requirement for alternative products, as innovative materials may also provide effective solutions when approved. Hence, the focus on approval and meeting equivalency standards is the most critical aspect of ensuring that alternative infiltration trench products are appropriate for use in onsite wastewater systems.
