What Size Septic Tank Do I Have?

“How do I know what size septic tank I have?” is probably one of the most commonly asked questions we have people ask us at Adelaide Hills Septic. Septic pumping pricing does depend on the amount of waste we pump from your tank, so it’s good to know beforehand!

If your septic lid isn’t exposed, it will need to be dug so that we can access it to pump. It's the size/type of lid that usually helps determine the size of the tank, which you’ll see in the following examples:

1620 Litre Septic Tank

1620 litre septic tanks usually have a lid that is approximately 2ft across and 3ft long as seen below:

2200 Litre Septic Tank

2200 litre septic tanks have the same 2ft x 3ft size lid as a 1620 litre tank EXCEPT there will be an extra smaller lid like the picture below with a hole in the centre.
**Always be careful around these lids, they can corrode and it's easy to fall through!
