Which tier can install pumps, grease traps, and mounded systems?

The correct tier for installing pumps, grease traps, and mounded systems is Tier 2. This tier encompasses a greater level of complexity and technical requirements compared to Tier 1. Specifically, installation of pumps is necessary for systems that require lifts due to terrain challenges, which falls under the more advanced capabilities associated with Tier 2. Additionally, grease traps are integral to managing wastewater in commercial and food service environments, highlighting the need for specialized knowledge in installation practices, materials, and codes that Tier 2 practitioners are trained in.

Mounded systems, which are used when conventional systems cannot be installed due to poor drainage soil conditions, also require a level of expertise in site evaluation and system design that aligns with the requirements of Tier 2 professionals. Consequently, those trained in Tier 2 are prepared to manage these more demanding installations effectively.

Tier 1 is typically limited to simpler installations that do not require this degree of technical knowledge, while Tier 3 involves advanced engineering or specialized design activities beyond what is necessary for these facilities. Thus, Tier 2 is the correct designation for those equipped to handle the complexities of installing pumps, grease traps, and mounded systems.
