Excavating the site at the proper location for installing a septic tank is a specialized job for which Bruce Johnson Construction is your go-to excavation contractorThe professional and technical capabilities of the contractor are a crucial factor because the task is much more than digging and removing soil and involves quite a bit of engineering. Correct septic excavation is essential for ensuring the proper function of the septic tank system, as you can ill-afford its malfunctioning. The excavation company can handle the entire project of septic tank installation. The scope of work includes digging the hole of the right dimension, soil compaction, placing the tank, connecting the tank outlet to the main sewer line, and then filling up the open spaces around the tank with concrete and other materials. 

Site inspection

When installing a new septic tank or replacing an existing one, the excavation contractor would first inspect the site to assess the condition of the land and ascertain how safe it will be to undertake the work. While soil testing is a pre-requisite for a fresh installation, inspecting the site is mandatory for replacing a septic tank. The inspection helps to understand the septic tank system and piping layout, which is necessary to plan for the excavation process and decide the type of equipment necessary for the job.

Soil assessment

Soil testing helps to assess the soil condition at the site of septic tank installation. The quality of the soil concerning compaction and water absorption is critical for septic tank installation by ensuring proper drainage. Performing a drainage test helps the excavation contractor understand the site’s suitability for handling the specific type of waste removal system.

Deploying the right equipment

The excavation company has all kinds of equipment, small and large, to handle excavation projects of any size. Based on the dimensions of the septic tank and the number of tanks, the company uses earth-moving equipment like excavators and backhoes as well as cranes, front-end loaders, dump trucks, and skid steers. The equipment operators have the necessary certification for operating heavy equipment that bears testimony to their professional abilities. The company maintains a fleet of heavy equipment of different sizes to execute projects of any size, small or big.

Depth of digging

The excavation contractor works out the exact depth for digging to place the septic tank safely and ensure its proper functioning. The depth of digging depends on the surroundings and the location of the piping system that connects with the septic tank. Moreover, keeping the entire septic tank system a few feet below the surface ensures that it remains invisible, although people might know the location. 

Using gravity

During the placement of septic tanks, gravity plays a crucial role in ensuring satisfactory removal of septic waste and water through the household’s plumbing system connected to the household drainage system. The depth of the tank and its orientation or position affect the impact of gravity by maintaining the proper slope.

The depth of the tank must be slightly above the drain field so that water flows out smoothly from the septic tank.
