Well, if you know the size of your tank and how many people are using it, you can use those numbers to get a ballpark estimate of how often your tank will need to be emptied.

But if you or the previous owner of the house decided to invest in a ridiculously large tank, you may be able to go over a decade without needing to empty it out.
As a general rule, unless something gets caught where it shouldn’t and clogs up the system, there is no problem in letting sludge accumulate in your septic tank. Sludge only becomes a problem when it fills the tank to the point where it might start overflowing. This is why tank size and usage are the two main factors in how soon you’ll need to get it drained.
If you don’t know the size of your tank or when it was last drained, then you should call a septic tank emptying Norfolk service provider and ask for an inspection. Waste removal companies are usually easy to find online, as this website shows.
