As soon as we had approval from the authorities to build our coop, I was ready to roll up my sleeves and get started. I was itching to start on the building itself, but I knew that I needed to run water and power out to the building site first. I called up a local equipment rental place and reserved a Ditch Witch for Saturday.
As Saturday approached, I was struggling to figure out just where to tap into the house water lines. The original owner and builder of our house must have had a connection to a cement company because the area around the house has an over-abundance of concrete. Every side of the house is surrounded by wide sidewalks and stairs that would make the task of running a pipe into the basement very difficult.
I spent several days polling the opinions of my family experts (my father and father-in-law) and the guys in the plumbing aisles of
Lowes and The Home Depot for the best solution to the problem. The resulting
consensus was that I should avoid the concrete altogether by tapping into the water line between the wellhead and the house. After confirming that the well water line was plastic and thus easy to splice into and that the water pressure check valve was located at the bottom of the well thus insuring that the line was pressurized at all times, I decided that we were going for the well connection plan.
If I was going to go through all of this trouble, I wanted the water to be available at the coop year-round. I called up the local building code department and found out that the average depth of frost required water lines to be buried at least 42" deep. Since the trencher had a 48" cutting blade this didn't seem to be a problem. Since the coop was not going to be heated I planned to bring the water up into the building using a yard hydrant that would shut off the supply four feet below ground level to prevent bursting pipes in the winter.
I borrowed a truck with a
trailer hitch and brought the trencher to the farm. The boys and I excitedly fired it up and I
positi
oned it at the coop site to begin the first trench. Within minutes, the first signs of trouble showed up as the water-soaked soil came up out of the trench with the consistency of pudding and the machine dug
itself to the axles in mud. With some creative maneuvering, the application of some bricks and boards for traction and a liberal sprinkling of curses, I managed to complete the trench at the coop site.
The trenching in the yard went much more smoothly as the soil as much drier. I was becoming increasingly aware that my rental turn-in time of 5pm was creeping up on me so I increased the pace of operation to insure we could return the machine and avoid paying for an extra day. Everything was going smoothly except for the fact that we kept running into bread-loaf sized rocks that had to be extracted from the trench-bottom by hand before we could resume.
As I was nearing completion of the job, Fred, a family friend, stopped by on his bike to check on our progress. Fred is a tree-trimmer, chimney sweep and beekeeper who is
knowledgeable about a great many things. Upon surveying our trench at the coop site he pointed to a fatal flaw in my great scheme. The groundwater had filled the trench to a depth just 18 inches from the surface which meant that my yard hydrant would never drain and would burst in the first hard winter freeze.
Fred's observation raised a very serious concern for me. Since I was tapping into the line at the wellhead, there was no way to turn the water off in case of a burst pipe at the coop other than cutting off the power to the well and completely losing all water for the house! Fred and I tossed around a f
ew ideas to deal with the high water table including burying a 55 gallon barrel full of gravel to create a drainage area for the hydrant and a sump pump to remove the water.
Having finally completed the trenching, we hosed off the machine, loaded it up and headed back to Howell to return it. We managed to get there just at 5pm but not without incident. Just as we were approaching the last curve going into town, I was paying a little too much attention to my conversation with Aidan and Sean and not enough on my driving. I took that last curve a little fast and the three of us experienced a white-knuckle slow-motion moment of terror as the trencher and trailer bounced, tipped and
careened back and forth in the rear-view mirror.
I was fully convinced that the machine was either going to fall off or the trailer was going to come unhitched from the truck and swerve into oncoming traffic. In the end my application of the brakes was enough to settle it back into line and I breathed a huge,
shaky sigh of relief. I was so happy to unhook that thing from the truck and hear the guy at the rental place say that everything looked fine with the machine.
After several more days of agonizing over a solution to my ground water problem, a practical solution came to light. My brother-in-law Tom, Sean and I were placing the water line in the trench and we discovered that my haste to complete the trenching job had caused the trench to be shallow from
backfill to a depth of three feet instead of four. The prospect of having to dig that bottom foot back out by hand would have added a couple of days of difficult digging to the task and we were suffering repeated cave-ins due to the wet soil.
Tom made the wise suggestion that it would greatly simplify things to back away from the goal of using the water line in winter, bury it more shallowly and plan to blow it out each fall. Sean made the wise suggestion that I move the hydrant to the well end of the pipe to provide a safety cutoff below ground to prevent a potential disaster of losing all of our access to the well. That plan also required much less expensive hardware. All of that finally settled, we are now ready to begin building the coop!
