Our septic tank is part of a system that consist of the two septic tanks that then flow into Ecopods that then flows into an existing septic tank where it is then pumped into a field. In our case, would the septic tanks themselves have to be vented or does the vents on the buildings get the job...
I have a couple of septic tank/system questions.
Does a 1500 gal tank and a 1000 gal tank (both compartmentalized) connected in series do the same job as a 2000 gal tank (baffle wall)?
When does a septic tank need to be vented?
