Did you know about 25
percent of the U.S. population relies on decentralized--or onsite--wastewater
treatment systems? About 95 percent of the onsite wastewater disposal systems
are septic tank systems.
If you own a septic
system, it is important that it be properly maintained. How often you need to
pump the solids out of your septic tank depends on three major factors:
-
The number of people in your household
-
The amount of wastewater generated (based on the number of people in the household and the amount of water used)
-
The volume of solids in the wastewater (e.g., using a garbage disposal will increase the amount of solids)
Although your septic tank
absorption field generally does not require maintenance, you should adhere to
the following rules to protect and prolong its functional life:
-
Do not drive over the
absorption field with cars, trucks, or heavy equipment
-
Do not plant trees or
shrubbery in the absorption field area because the roots can get into the
lines and plug them
-
Do not cover the absorption field with
hard surfaces, such as concrete or
asphalt. Grass is the best cover,
because it will help prevent erosion and
help remove excess water
-
Do divert surface
runoff water from roofs, patios, driveways, and other areas away from the
absorption field
Homeowners wanting to take good care of their
septic systems should make note of the following
items that should never be flushed down the
drain or toilet. These items can overtax or
destroy the biological digestion taking place
within the system or clog pumps and pipes.
Do not flush the
following:
-
hair combings
-
coffee grounds
-
dental floss
-
disposable diapers
-
kitty litter
-
sanitary napkins
-
tampons
-
cigarette butts
-
condoms
-
gauze bandages
-
fat, grease, or oil
-
paper towels
and NEVER flush
chemicals that could contaminate surface and groundwater, such as:
-
paints
-
varnishes
-
thinners
-
waste oils
-
photographic solutions
-
pesticides
