Do not flush the following items! These items can quickly
fill your unit with solids that cannot be treated, and will require that you contact a
licensed contractor to pump the system more frequently.

The most common private sewage system installed nationwide is the septic tank followed
by a subsurface seepage system. Since this system depends on the absorption
properties of the soil, it must be installed in soils which drain well and are not affected by
a seasonal high water table. To determine the suitability of the soil, a percolation test
must be conducted prior to installing the system. Once the test results are known, it can
be determined if a field will function properly and if so, how much field is necessary. If
your percolation tests do not pass, then one of the following types of alternative systems
must be considered.

  1. First choice of system for soil that will absorb septic  tank discharge
  2. Usually lower installation cost
  3. Low maintenance, simply pump septic tank every 2-5 years
  1. Requires soil that will absorb septic tank effluent (clay soils unsuitable)
  2. Extreme high water tables interfere with proper function

When choosing which type of system to use, certain factors must be considered so that the system
selected will best serve the individual's needs:
  1. Type of soil on the property
  2. Topography (lay of the land)
  3. Lot size; available property for the installation
  4. Surrounding features - wells (both yours and the neighbors'), water lines,  property lines,
    driveways, etc.
