A basic septic aeration systems have two basic working parts:
1) An aeration or septic tank.
2) Absorption field. (Also called a Drain field.)
Waste flows from your home through your home’s plumbing system to the septic tank.
The aeration/septic tank is nothing more than a holding space for waste (liquid & solids). The solid waste is digested in the tank by aerobic and/or anaerobic bacteria. Digested solids settle to the bottom of the septic tank creating a sludge layer.
As the sludge builds up in the tank it limits the tanks capacity and space for the bacteria to do its job.
When the sludge level gets too high it will begin to transfer into the drain field. The sludge fills the drain field and pores in the soil and destroys your drain field causing surfacing and can cause a backup in your home or sewage in your yard, costing thousands of dollars to replace.
Maintaining your septic system properly is a must to prevent sewer backups and can save thousands of dollars in the prevention of premature drain field failure.
