: Should a septic tank emit odour? : It is our first house with a septic tank and during the high use periods, ie during clothes washing, we notice the smell. : We have been advised that septic tanks should be odourless. Is this true? Any advise would be appreciated.Yes a septic tank gives off sewer gas, this is usually vented away through the plumbing roof vents and is not noticed. Do you hear any gurgleing in fixtures during high usage? if so, the syetem is overloading, blocking vent take offs and the gas is being pushed inside.
