How does a septic system work?
A septic system has three parts that work together to clean wastewater from your home. First a pipe carries the water from your home into a large concrete or fiberglass tank. Here solids are separated from liquids and allowed to collect at the bottom of the tank where bacteria then works on the solids to partial decompose them. Oil and Grease float to the surface as scum and the waste water flows through a T-shaped outlet in the septic tank that prevents the solids and scum from leaving the tank. Screens or filters

may be used also to insure that only liquids go into the next step which is the drainfield. The drainfield is a series of perforated pipes buried in soil that allow the waste water to percolate into the soil removing hannful bacteria, viruses, and other remain items.
How do I know if there is a problem?
Look for the following signs:
Problems flushing toilets
Plumbing Backups
Grass that is greener or growing faster in one area of your yard
Mushy wet spots in the yard
Odors on the inside or outside
How often should my tank be pumped or inspected?

What are some things to avoid that can damage the system?
Use caution what you put into your system. Dental floss, feminine hygiene items, diapers, cotton swabs, cigarette butts, coffee grounds, paper towel, paints, solvents, large volumes of toxic cleaners and grease can all damage the system. Garbage disposals also add a strain on a septic system by introducing solids that the bacteria does not breakdown. Try to avoid overloading the system by spreading out laundry loads throughout the week rather than doing several loads on the same day. Avoid driving over or parking on your septic system as this can damage it. Only grass should be planted near the system to prevent roots from clogging it.
