We all live in watersheds, which are the areas that drain to a common point in a river or lake. Our actions in a watershed determine the quality of
water downstream.

Water cycle: one of the oldest “recycling” schemes in nature.
Water vapor condenses into clouds, and returns to earth as precipitation (snow or rain). Some of this precipitation runs off the land surface and some soaks into the ground.

Ground water accumulates when surface water soaks into the soil and moves downward. The water table is the upper most depth of the “zone of saturation”. Wells tap into the saturated zone, where all spaces between particles are filled with water.
Underground deposits of water in this saturated zone are called aquifers.

Do you know???
Where your tank is? How big it is? When it was last
pumped? The location of your
leachfield?

To pump... or not to pump
Pumping costs about $200 for the average 1250-gallon tank, every three years or so
A new leachfield costs from $5,000 for an inground system to as much as $20,000 for an engineered field
Which would you choose?

What can I plant on or near my leachfield?
Grasses Perennial and
annual flowers Many perennial
groundcovers
All trees Large shrubs
OK to Plant Avoid Planting

Other causes of septic failure Overloading. Use water
sparingly. Do only full loads of wash at off-peak times, if possible, and try to limit the number of loads daily.
Placement in poor drainage area
Water leaks Driving over the drainfield

Other causes of septic failure
Pouring kitchen grease into drains
Failure to install according to septic codes
Flushing cigarette butts, sanitary napkins or other inorganic materials down the toilet

Other causes of septic failure
Extensive use of garbage disposals Tree roots clogging pipes - contact
a septic contractor for repairs Use of salts and chemicals from
water softeners and washing machines

What about additives?
Enough bacteria are present in the tank from normal bodily wastes
Additives cost $$$ and may actually increase the solid material in the tank by producing inert ingredients
There is no substitute for pumping!

Tips to keep your septic system working well
Don’t water the leachfield Don’t flood the system with
excessive water use Keep excess solids out of the
system and avoid flushing toxins down the drain

Tips to keep your septic system working well
Avoid using your garbage disposal to process large quantities of wastes
Regularly pump out the septic tank and inspect the physical components of the system
Don’t park or drive over the leachfield
