What type of systems can Tier 1 installers manage?

Tier 1 installers are specifically trained and authorized to manage gravity-fed residential onsite wastewater systems. These systems are simpler in design and operation compared to other types of systems, making them suitable for installers at this training level. The focus on gravity-fed systems allows these installers to effectively install and maintain systems that are commonly found in residential settings, ensuring they adhere to the necessary regulations and standards outlined by SCDHEC.

This specialization helps to ensure that installations are conducted safely and efficiently, reducing the risk of environmental contamination associated with improper wastewater management. The other options represent types of systems that require different levels of expertise or technology, which are not covered by the Tier 1 training.
