Step 16: Drainage.
Well, it's been two months since I posted an update. Sorry for my delinquency. My biggest reason for procrastinating is that Photobucket now seems to be blocked at work, and I have a slow limited-bandwidth connection at home.
Anyway, I really HAVE been busy working on the barn, even though I'm at the stage where a lot of the work doesn't really show.
I ran drainage lines for the roof gutters and the wash rack, along with about 1400 feet of water and electrical lines out to the pastures. I realize the latter doesn't fit under the category of drainage (or really even in the category of barn-building), but it all involved digging lots of trenches so I'll write about it here anyway.
On the north side of the barn I ran a 4" PVC drain line about 150' long. It drains the gray water out of the catch basin in the wash rack, as well as the two downspouts on that side of the barn. One of my buddies with a little baby Kubota BX-24 came up and dug that trench for me with his backhoe. My tractor's a lot bigger, but I'm waaaaaay jealous of the backhoe. I really need to get one sometime soon. It ended up taking the entire day to dig the trench, so I ruled that out as an option for the other 1400' that had to be dug.
I was all set to rent a ride-on trencher for the weekend for around $350, but had to postpone at the last minute. I'm glad I did. In the meantime, I bumped into a friend who referred me to a friend-of-a-friend of his with a landscaping business. My friend told me this guy had dug 1000 feet of trench for him with a Bobcat for $200. I called him up, and he showed up the next day. It took him 4 hours at $65/hr; he charged me $250 when all was said and done. All I had to do was stand around and watch (which is NOT what I'm used to when it comes to this barn!). Anyway, money well spent in my opinion.
There was one relatively short trench (~75 feet) for the drainage line for the downspouts on the south side of the barn. There was a second trench about 700' long for water and electrical lines out to the five horse paddocks adjacent to the barn. Then there was a third trench about 600' long starting at my house and running out to the four paddocks on the other side of it.
The water lines were relatively straightforward. I ran 3/4" PE pipe in 500' rolls, then installed a frost-free hydrant at each water-trough location. (Okay - actually I've only installed two so far; I still have to go pick up the others at the store).
Along with the water lines, I also ran 3/4" gray PVC electrical conduit, through which I pulled the electrical line. In case you're wondering why I ran electrical lines out to all the pastures, it's for water trough de-icers. It's not any fun (or really even feasible) to carry 3 or 4 buckets of warm water out to each of nine different water troughs several times a day on cold January days. The de-icers I need are 500 watts @ 120V, and with runs up to 700' long with five de-icers in parallel, voltage drop on the lines is a real issue. I ended up finding a guy on Craigslist selling two 1000' spools of 12/2 Romex for about half price. I bought all the wire and split about a third of it into its two separate wires. That gave me about 1300' of 12/2 plus an extra wire. (Obviously it would have been easier if I could have bought 1300' of 12/3 wire for half price, but that wasn't an option). With the extra wire, I can run half the heaters off one hot wire and the other half off the other wire, thus cutting the current draw by half. Furthermore, since the wires are opposite polary, the return current through the neutral cancels, thus cutting the ohmic losses (i.e. voltage drop) by half again. (We'll ignore the fact that one of the runs has an odd number of heaters).
Once everything was in place in the trenches, I filled them back in with my trusty tractor.
As usual, here are some pictures:
