Septic systems do not come in one design. They are represented by systems that are configured in one of various designs. For example, the styles of septic systems that are commonly installed include the following:
• Gravity systems
• Pressure distribution drain fields
• Sand filter systems
A Gravity Design
As you might guess, a gravity septic system installation in Bellingham WA is one where the force of gravity is used to drain the effluent from a septic system’s tank. The effluent flows into a number of trenches. Therefore, the drain field must be under the draining level of the tank. Otherwise, a pump is needed and the system is referred to as a pump-to-gravity design.
In this type of septic system installation, the soil under the drain lines filters the effluent as it travels through pore areas. Biological and chemical process are used to treat the waste as it moves down through the soil. The treatment is meant to clean the effluent before it comes into contact with the area where the groundwater is stored.
Therefore, this septic system installation works best when the soil is drier and the depth is great enough to facilitate cleaning. The drain field size depends on the condition of the soil and the amount of daily wastewater.
Pressure Distribution Designs
Pressure distribution drain fields are normally installed when the soil depth is not great. Because this type of septic system features a pump, the drain field or leach field regularly receives effluent. A number of pressurized lines running from the pump ensure that the drain field receives the effluent from a household.
