The Hunt for the Water Line, Trenches



Yesterday we got the last window in Kuti-A installed, plus finished the interior walls and put in a trench for greywater. At the end of the day a hose blew out on the backhoe.
Today the trenching continued. Roger's Deere backhoe got a good workout, after minor repairs.
We went looking for the water supply cutoff valve to the barn by scratching (shallow excavation) in front of the rollup door. The valve is probably there, but we just couldn't find it. After excavating about 250 square feet we gave up and decided to tap into one of the lines connecting a nearby frost-free water tap.
Next we went looking for the septic system cover and found it on the first try. As expected it appears unused, but it is full of water suggesting that the local rain and snow-melt accumulates there, probably because the access port is in a depression. We'll mound it up when we re-bury it.
I started wall layout in the barn for the central facility but quickly ran into several small issues. First I'm getting a cold or something and feel pretty awful. 2nd there's a perforated pipe that vents the underside of the floor deck which runs exactly where I want to put the main waste stack. Will have to re-route it. Next we went to put in a trench for the greywater line and started by scratching down along the side of the building to find the base of the foundation. We were assuming a poured foundation and quickly discovered that we're dealing with a a wooden foundation the first I've ever seen. That was good news in a way because now we don't have to drop our greywater line very deep to go below the base of the foundation, we can go right through the side of it. On the other hand I reckon a wood foundation won't last as long as a concrete poured foundation would do. Next we went to dig a greywater trench and ended up cutting the sewer line.
A mixed bag day for sure.
