SEPTIC SYSTEMS
What is a Septic System?
A Septic System is an underground on-site wastewater treatment system.
How do Septic Systems work?
The Septic tank is a watertight container made of concrete or plastic. Waste flows from the house into the septic tank where the material is broken down into three main materials. Organic matter floats on the top (Scum Layer), Inorganic matter sinks to the bottom (sludge Layer), the layer in between these two is grey water. Septic tanks function full of water. Every time water and waste are introduced into the tank an equal amount of grey water is discharged into the drain field. If the top layer and the bottom layer become thick enough the solid material will be taken out into the drainfield. Solid material in the drain field can cause costly drain field failure. Pumping the Septic tank reduces the build up of the two layers and reduces solids entering into the drain field. A drain field is the part of the system that disposes of the grey water. Buried pipes or chambers carry grey water away from the tank where the water is absorbed into the earth, some water can be disposed of through surface evaporation.
Healthy Septic Practices
-
Dripping faucets and running toilets kill septic systems.
-
Don't drive on septic systems or drain pipes.
-
If the system is less than 4 feet deep ask about freezing concerns.
-
Pump every 3 to 5 years.
Caring for your system
-
Periodic pumping
-
Adding a bacteria treatment (M & M Provides)
-
Following best practices for a healthy septic (see above)
Understanding your sewer line
The waste from various bathrooms, laundry, sinks etc. is carried out of the house in a single line. In a correctly installed septic, there will be a cleanout/ inspection port just outside of the foundation, see photos to the left for visuals. This is NOT where you pump the tank! If you are experiencing slow draining or water backing up in your home this cleanout/inspection port is a valuable tool. Remove the cap. If you look into this clean-out and see water backing up it's likely there is an obstruction between the clean-out and outlet of the septic tank. If there is no water in the clean out then the obstruction is under the house.
Pumping the tank
-
The tank is pumped with a vacuum truck.
-
The closer the truck can get the better, distances over 40 feet may add extra time and expense.
-
The truck is HEAVY, solid ground is a must.
-
It is the customers responsibility to provide stable, load bearing ground.
-
The tank pumping access points need to be uncovered (unburied) by the customer prior to our arrival.
-
The customer needs to go out and look into the access and be sure they can see the waste.
-
The pumping ports can be no smaller than 6 inches.
