Ok guys its been quite the day. So my friend who has the excavting company showed up first thing this morning with a couple of his guys and his excavtor. And Just like he is a good friend he is also great at what he does and did a fantastic job.

First up was to unload the septic tank, handy to have a tractor haha....

And that is where the day became interesting. I had talked with the wastewater engineer and told him, I thought given the depth of the sewer pipe the tank and the entire field needed to be lower I was assured twice that they had it all figured out and it would work out...
Well It did not they were off by about 12 inches. To make matters worse when I tried to call the engineer today to sort out what to do he was taking a few days off. Might have been nice if he mentioned that when I talked to him on tuesday afternoon and said I might be calling with questions. I tried every extension at his office and got another engineer who I told the situation to and he agreed to come out and help me figure it out. He took some measurements, had us dig a 10ft deep test hole and calculated a bunch of stuff on his laptop and re-designed the field on site to sit approximatley 12inches lower on site.
He said the soil where I live was the best of anywhere due to it being pure sand and this wouldn't work anywhere else but everything calculated out and basically the whole thing just got about 12inches deeper. That means 12inches more clear crushed gravel I have to buy but it could have been worse.
There was also some concern that the tank could not be burried deeper than 24inches (we are around 30 deep to the top of the tank but after the engineer talked to the manufacturer on the phone he said up to 48inches is allowed. Phew! all good, I will just need to buy more risers.
This hole for the tank was almost 7ft deep to the bottom!

The next issue that came up was I had a whole list of fittings etc... that I ordered and picked up from southern irrigation. They told me all the fitting were inside the distribution box which was wrapped in packing tape, great...well my bad I was in a hurry yesterday and did not take the time to check over all the fittings...I asked for 4in ABS couolere they gave me 3in, I asked for 45 degree elbows I got 90's, I asked for ABS to PVC adapter and I got nothing, I needed 3in caps for the septic lines I was given 4in caps...Wonderful!
Well thankfully a quick run to homedepot solved that and I can return all the wrong stuff when I get my risers, but gosh there must have been some sort of miscommunication that so much stuff was messed up.
Anyway my friend and his guys were great, they said this happens to them everyday, and after I got the fitting we did all the plumbing into and out of the septic tank and the engineer looked it all over and approved it.
Since the hole was deeper than anticipated my friend suggested that even though its all sun in the forecast we should at least backfill up to the pipe level around the tank to prevent any sort of unplanned cave-in. so we did that and compacted it and then I added 200 gallons of water...I need to add more but will do that tomorrow as I only had time for one run with the water tank.
Anyway there was a little time left at the end of the day so I figured there would never be a better time than now to excavate my planned drainage basins.
This one is in a low spot just north of the shop, The basin is 2ft wide×3ft deep and 6ft long, I'll wrap it with fabric and put some clear crushed or drain rock in it and a sump. should get rid of the small amount of standing water that was in this area during very heavy rains.

I also had a spot excavated on the south side so that I can drain the downspout into it and eliminate the splash pad that tends to get driven over.

This one is 3ft wide, 5ft deep and 7ft long. I'll put a sump and infiltration barrell surrounded by clear crushed in this basin.
Anyway. That's all for now but more updates to come as i'll be busy working to finish all this outdoor stuff the next few weeks.
