Installing a Septic System

Step 1: Create the Tank and Field Layout

Earth Excavating can Design and Engineer your septic system. Septic systems incorporate a plastic or concrete holding tank in which wastewater and waste materials from sinks, bathtubs, showers and toilets are deposited. The waste collects in the tank where enzyme and bacterial action begin breaking down the waste products, converting them into a liquid. As the level of liquid rises in the tank, it eventually reaches an overflow pipe, and is then directed into a series of covered trenches known as the drain field.

Lay out the areas for the septic tank and drain field, closely following the plans approved by the building department. Regulations determining setbacks, distances from wells and other considerations are based on health requirements and must be adhered to.

Alternative septic

A backhoe is needed to excavate the hole for the septic system’s tank, or tanks -- some municipalities require an additional overflow tank between the main tank and the septic field.

Measure the depth of the hole for the septic tank and dig to that level.

Step 2: Install the Septic Tank

When possible we use Infiltrator Systems Chamber systems rather than old style rock leach fields. They are easy to install, engineered for strength and performance, they have greater design flexibility including a smaller footprint as compared with stone and pipe, and are made from recycled materials. These advantages of Infiltrator chambers add up to cost savings on labor, materials and time savings on the job. Click more to learn about the benefits of chamber systems.

Step 3: Prepare the Drain Field Trenches

Use the backhoe to excavate the drain field trenches according to the plans.

Attach the overflow pipe that directs the liquid from the septic holding-tank into the trenches.

Step 4: Backfill the Tank and Field

Carefully place the dirt backfill around the septic tank to avoid breaking or disconnecting the overflow pipe.

Backfill the trenches, completely covering the septic medium with dirt to the depth specified in the plans.

It is important that the septic system be sized properly, constructed properly, and maintained. That’s why Earth Excavating takes care of all the work needed to get the job done, including obtaining proper permits, taking measurements and sizing, ordering supplies, and overall complete septic system and tank installation. We have the septic system to fit your home and meet your needs. If properly installed and maintained, a septic system is an efficient way of dealing with waste and can last for many years.
