treatment plant

need to replace old existing septic tank and would like to install best possible TP

have used Matrix before (pumped outflow) and found it OK apart from noise of electric stuff - in 6 years had to replace pump 3 times

Ok, what are your particular preferences?

Does it need to be pumped, if you are replacing a septic tank, you may (hopefully) get away with a gravity outlet?

 

GrafOne2Clean, Klargester Bio Air.

 

Both good plants, have no media and easy to cleanout etc.

 

I prefer the Graf plants as they have more options for control panels, and secondary treatment etc. But ideally, you want a tank with no media or moving parts (less to maintain).

the previous Matrix was pumped due to the fall being a little difficult, with the present location that would not be an issue and therefore a gravity outlet will be the target. 

I suppose that having experience of the Matrix then to install same again would be the way to go, just trying to assess if there might be a better option out there.
