Have already checked the previous forum for threads , so does anyone have experiance of seeing/helping/installing/paying for a septic tank? how much space does it take up including soakaway? what approx costs were involved? we were quoted €8000 a couple of years ago! which seemed a lot even at the height of the boom just for digging 1 deep hole and a couple of gravel filled trenches , no doubt there is more to it than that , anyway thanks for any info , cheers Geoff .
