Septic Tanks Make News
Experts in the field tell us that the major cause of septic tank failure is neglecting to pump out the tank every one or three years. When too much scum and sludge flow from the tank that is filed with solids the leakage ends up in the drain field and plug up the soil, the sand and gravel. This obviously causes the whole system to back up and fail.
Excessive water used over a short period of time (lots of showers or loads of laundry in one day) and adding harmful chemicals are two more additional causes for septic tank failure. If excessive water enters the system, excessive water must flow into the drain field. All this water stirs up the tank and non-biodegradable products flow out of the tank and into the drain field where they plug pipes.
Other things that cause septic tank failure are: Improper installation or design; Clogged or broken pump in a mound system; frozen pipes or saturated drain fields.
Regarding the bacteria question. Experts tell us that you do not need starters, feeders or other additives to keep your system working. Your system is filled with naturally occurring bacteria. These bacteria will break down all solids if you limit the disposal of harmful products and harsh chemicals into your system.
