The collection wells were plumbed into our septic tank yesterday and I back filled (by hand) the pipe and the top section around the new tanks.
Its starting to look a little bit more tidier now.
I pumped out some more of the water from out of the peering holes and they dont seem to be filling in in too much of a hurry.
Spoke to our SS and we are booked in for this Tuesday to have the holes concreted and our formwork finished.
Fingers crossed, we might see our slab poured by the end of this coming week.
