What type of property does an installer work with?

Installers primarily work with onsite wastewater systems. This includes various tasks related to the installation, maintenance, and repair of systems designed to treat wastewater from homes or businesses in a localized manner. Such systems might include septic tanks, leach fields, or other forms of decentralized sewage treatment. The expertise required for this type of work is specialized, as installers must understand local regulations and environmental considerations to ensure that these systems function safely and effectively.

Residential properties do commonly utilize onsite wastewater systems; however, installers are not limited exclusively to residential settings, as these systems can also be found in certain commercial applications. Agricultural land involving drainage solutions and environmental assessments for commercial buildings are distinct from the primary focus of an installer, which is strictly related to the setup and care of onsite wastewater systems. Thus, the correct answer highlights the specific area of expertise that installers engage with in their profession.
