Septic Installation Andover/Ham Lake MN

When owning a previously owned home, or purchasing a new lot, every aspect of the construction is your responsibility. One of the most common things homeowners tend to look over is the septic system. Knowing what type of septic system is required for your home, and how to care for it, is a very important step that should never be skipped. Below is some important information about septic systems that can help guide you before you decide.

Types of septic systems and how they are installed:

There are four common types of septic systems, which include:

• Gravity Septic Systems — is known as the basic or “standard” system typically installed. This type uses gravity to transfer effluent (waste) through the septic tank and into the drainage area.
• Pressure Distribution Septic System — commonly known as a pressurized bed system, is used in which the pump circulates effluent throughout the drain field in one motion. This type is generally used in newer systems because it is the most efficient, as it makes better use of the whole drain field. The pressure distribution septic system uses the same toilet pipe and tank as the gravity system. This system needs a compartment tank known as a lift station, which pushes the effluent out. The lift station then forces the liquid to trenches or a bed of rock.
• AT-GRADE Septic System —  is arranged to be at ground level for homes whose installation sites are too deep to create a mound, but too flat to install a below-grade system. There is both a lift station and a tank reserved for solids. The ground is then dug up and replaced with a bed of rocks. A pipe drilled with holes in it is placed on top of the rocks, then covered with more rock and geo fabric.
• Mounds Septic System — is installed if there is not enough soil in the area for treatment, and the drain field is raised above ground level. This type of septic system requires a lifting station. The installation process is much like the AT-GRADE system, however, it starts with a mound 1 to 2 feet of sand. After the geo fabric is placed on top of the pipe, a sandy loam cover is added and camouflaged with black dirt.
