The average septic system lasts for 20 to
30 years, although some systems may have a longer usable life. Eventually,
though, you will need to replace all or part of the septic system on your
property. Knowing when to begin replacing system components is a must if you
want to avoid sewage backups.
1. Septic System Capacity Needs Have
Changed
Septic system capacities are typically
determined by average water usage. If your household uses under 500 gallons
of water daily, which is the amount used for the average one- to three-bedroom
home, then a tank capacity between 900 and 1000 gallons is sufficient.
On the other end of the spectrum, a
five-bedroom home will likely use closer to 900 gallons per day and require a
1500 gallon septic capacity. If renovations, an increase in family size, or
higher water usage has occurred, then you may need to replace the tank with a
larger model.
2. Water Testing Shows Contamination
Many homes on septic systems are also on
well water, which means monitoring the water quality is vital. Even a municipal
water source can become contaminated, though, if your septic system fails. If a
water test of your well or tap water shows contamination from sewage, then you
need to inspect your system for leaks. If the damage is extensive, install a
new system.
Although home water testing kits are
available, you will get more accurate results if you contract testing through a
professional facility. This is a sound investment since the quality of the
water can directly impact your family's health.
3. The Tank Has Developed Damage
A crack in the septic tank itself requires
immediate replacement; otherwise, sewage will leach into the soil and make its
way into groundwater. Signs of a leaking tank include greener grass over the
tank and standing water that smells like sewage. One way to minimize the
chances of a leak is to inspect the tank at least once every five
years, although you may want to schedule more frequent inspections for
older tanks.
In some cases, a damaged tank is repairable,
especially if the problem is caught early in its development. Otherwise, the
leaking tank will need immediate replacement to prevent more sewage from
entering the ground.
4. Drainfield Failure Has Occurred
The drainfield is located downslope from
the main tank, but it is still a vital part of the septic system. The microbial
activity that starts in the tank is complete in the drainfield as the effluent
percolates through the soil.
A drainfield should have no buildings nor
trees. Further, you should avoid driving on it or doing any activity that can
compress the soil. If the drainfield becomes damaged, raw sewage will begin to
collect on the soil surface. Once this occurs, the drainfield will likely need
replacing or even moving to a new location, which may require the replacement
of the entire septic system.
5. The Main Effluent Lines Don't Work
The effluent or sewer lines route waste
between your home and your tank, as well as the processed sewage from the tank
to the drainfield. If the lines don't flow properly, they can begin to leak or,
worse, damage the tank or drainfield.
Leaking lines can usually be replaced
without the need to replace the entire system. Clogged lines, on the other
hand, can blow out the entire system if they aren't promptly addressed. Leaks
in the tank, valve damage, or drainfield failure are all possibilities. If your
drains back up or if sewage odors have invaded your house, you need to inspect
the system for clogs and damages.
