Where should the water level be in a septic tank?
A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).
How often does a septic tank need to be emptied?
All septic tanks require emptying ONCE A YEAR. They only hold 12 months sludge storage and if sludge starts to empty into the soakaway soil, it very quickly blocks the air spaces (porosity) in the soil, the effluent cannot soak away, you suffer a soakaway failure and the septic tank fills up, backing up the system.
What does it mean when your septic tank is full?
Smelling bad odors from the sinks, toilets, and even the washing machine can signify that your tank should be emptied. You may also notice a strong odor coming from your tank outside or bright green grass growing only in that area. But if you just had it done, you need to have the rest of your system inspected.
Why is the second septic tank more complex than the first?
The second septic system is more complex because it’s pressurized. Gravity still takes waste from the house to the main tank where solids separate and settle on the bottom. Overflowing liquid is then gravity-fed to a second smaller tank downstream.
What are the problems with septic tank overflow?

Can a septic tank be pumped out after a clogged drain?

Why is my septic tank filling up again?
Sometimes, even after it’s been pumped, it can fill up again right away. What exactly is it that causes this problem? If you just had your septic tank pumped or cleaned and it is already full again, it could be a problem in the drain field, a plumbing issue, or excess water usage.
