Leach Type System Identified
All the water that you are using in your home whether that be in your sinks, garbage disposal, toilet, shower, and even your laundry most likely ends up in the same place. After running through your plumbing in your house, the grey water flows to your tank and eventually out into your “leach” field. Below we will walk through the parts of your system. Although there are many types of SST (subsurface sewage treatment systems), we will be discussing a “Leach” type system with leach pipe or chambers.
- Clean out-As discussed in other blogs the water will first run through a cleanout into the tank. A cap to clean your mainline can also be used if the tank is over flowing.
- 1st compartment of your septic tank- this is known as the inlet portion of your septic tank. This is where the main solids will settle in your tank. This compartment of solids is made up of three layers. The bottom layer will contain sludge. The middle contains the effluent layer and the top layer is known as the scum layer.
- Between the 1st and 2nd compartments is known as the baffle. Although there are many different designs the baffle is there to keep the solids, scum, and sludge in the 1st compartment and allow only water to flow into the 2nd compartment.
- 2nd Compartment should only contain water.
- Effluent Filter- A filter on the outlet which is designed to keep solids from reaching your distribution box.
- Distribution Box happens to be one of the most important parts of the system. This box distributes flow evenly into your leach field. As a home owner, it is your job or a service providers job (maintenance plan) to change flow periodically through the year. This is important to extend the life of your system and promote optimal leaching.
- Leach field- is an essential aseptic to your system. The leach field is where your grey water will end up after your system has properly removed all the solids. The leach field is designed for the water to slowly drain into the ground. If this becomes clogged it can be costly as well as the potential to back up the rest of your SST. No solids or sludge should make it out to your leach field if your system is functioning properly.
- Inspection Ports-This viewing area allows a service provider a little bit of insight to check on the overall wellness of the leach field.

The type of septic system that a homeowner will be required to install will all depend on the soils around the proposed system. Has the soil in the proposed area been disturbed? What is the allowed distance of vertical separation to the ground water? The local health department and system installer will assist the homeowner in determining what type of system works best for that location’s specific soil as well as the homeowners needs. There are many different types of septic systems, for this article we will focus of four main categories of septic systems. Conventional/Gravity: This type of system uses a distribution Box (DB/D-Box). Gravity will pull water out of the tank into the D-Box, then evenly distribute into the leach field. This type of system will have no electrical components. However, it should still utilize an effluent filter to help prevent solids from entering the D-Box and into the absorption field. Pressurized/Drip: This system works just like the gravity system except it uses an electric pump. It is utilized when the soil around the site is not able to leach the water through, thus the pump will drive the grey water to another area within the property with appropriate soil. Alternative/Mound/Evapotranspiration: This system is used when the property has no appropriate soil for a leach field. Since there is no soil to absorb the water, the installer will then build a mound or sand filter. These alternatives are built to allow proper saturation when original soil will not allow it. Proprietary: This system is known as an ATU (aerobic treatment unit). It works by using an aerator to push oxygen into the septic tank so that bacteria can grow and allow for breakdown. After breakdown occurs grey water is displaced into the leach field.
Yeast is a fungus with a main purpose of breaking down chocolate and alcohol. You could also find yeast being used in the medical field. When human excrement is added to a septic tank, there are billions of micro bacteria working to breakdown that excrement. This natural breakdown allows the homeowner to go 3-5 years until their septic tank needs pumped out to remove the solids that remain. By adding yeast, this will NOT help to produce any needed additional bacteria in the tank. If you add yeast to your septic system it will compete with the existing bacteria, which could cause depletion of needed natural bacteria in your tank. Although yeast will help to break down certain starches, in the end, adding yeast is like dropping a pinch of salt into the ocean to try and make it a bit saltier. Yeast should NEVER be used as replacement for septic maintenance. Some of the solids that end up in the tank cannot be broken down by yeast or any other bacteria or enzyme. Therefore, it is essential that every homeowner must get their system serviced and excrement pumped out by a certified technician.

The cleanout pipe is a threaded cap on the outside of your house that is designed to help in the aid of cleaning the main line to your tank and to aid in the event of a backup. Blockage is always possible in the mainline. The cleanout allows you to “clean” the line with a plumbing snake or water if needed. If your system is backing up into your house, you can easily remove this cap which allows water and septage to flow onto the ground outside instead of the alternative of backing up into your house. Look to see if you have a cap outside your house and make sure it is accessible. Remember the importance of a cleanout and having a cap outside the home at surface level is an essential part of allowing your septic system to run smoothly.
