Have scheduled preventive maintenance. This can remove solids which settle and gradually
fill the tank.
Limit the water entering your septic tank, & give your
system time to rest after heavy use.
Use water-saving fixtures.
Repair
leaky toilets & dripping faucets.
Avoid using a garbage disposal. Garbage disposals add tremendously to the amount of solids entering your septic tank.
Discard grease in the garbage instead of the drain.
Grease can clog the septic tank or the soils surrounding the absorption
field. Also, use of liquid fabric softeners can contribute to
excessive scum in the septic tank.
Use toilet paper that decomposes easily. Purchase brands labeled "safe" for septic systems.
