Okay we have had a VERY productive day...
We bought the vault style drainage system and replaced everything from the septic outlet.From researching it each vault can be next to each other-minimising the holes you have to put in the yard.
We then went and rented an mini-excavator until Sunday.
The excitement started when we started to dig...almost the first bucket broke our water pipe...

seems the guy who built our house also thought it a WONDERFUL idea to run the waterline right next to the septic line.... :no:
So Mrs oz ran BACK to Lowes(a 50 mile roundtrip) to pick up repair parts and one extra piece of pipe..
I meanwhile dug and dug AND dug(it was quite fun really

) and managed to get most of the field done...
Mrs oz came back and was gluing the pipe and fixing that.
We finished the trench by hand-smoothing the bottom and leveling it and then went to test the water pipe-it leaked...
We gave up on that for the moment and installed the vaults-they went in pretty quickly although it did require a little work to get it level.
BACK to Lowes goes Mrs oz(lesson learned here-by at least twice as much as you think you will need) while I play around attempting to pull out an old oak stump-no luck.
I fill in some of the holes left from the old 'system' and attempt to back my truck down the driveway-fail miserably-what can I say,I am not a REAL man....
We had also bought some fabric that goes over the vaults(although it is not needed we figured it can't hurt) and started to put dirt back in...
Did I mention it was dark?
Mrs oz got back and we fixed the water pipe(hopefully-haven't tested it yet)
I gave up on trying to fill the field back in as it was difficult to see even with the lights on the excavator...
SO we called for a pizza for dinner and of course it was after 9pm and they wouldln't deliver out here...

so BACK out again goes Mrs oz-she is a trooper.
So hopefully everything will go smoothly tomorrow and we shuold have a working septic system tomorrow...
Costs have been:
$500 for the vaults,PVC pipes,elbows,PVC cement,etc(we DID buy too many vaults so we will get some of the $$$ back.
$175 for the excavator.
$40 or so for reciever,tow ball and pin.
The joy of doing it right-priceless.
