So this was the most recent project. We had no water in the garden area. This is what I had to do...dig a trench about 125 feet long, from the house, where the water is, to the garden, where it isn't...
I opted for hose for this project. Some might wonder why I didn't use PVC pipe? I thought about it, but I haven't worked with it before and it had to have several curves in it. Also, at each end, it would have required hooking it up to faucets with the accompanying plumbing connections, which again, I haven't ever done before. So I basically just opted for easier (in my opinion) and quicker so as to get the water to the garden as fast and reliably as possible.
As you can see below, I didn't just buy regular hose though, I got a larger diameter hose (this is 3/4") to allow for more water flow. It is also made for heavy duty applications and can actually be buried for use in sprinkler systems. I figured that would work just fine for us and it did.
I bought this tool and a trenching shovel. As it turns out, this was the better choice. Apologies for the blurry photo, it focused on the background and not the foreground. I'm still getting used to my new camera, ha.
What I did was just push it into the ground (which was, fortunately, soft from recent rains) and I just rocked it back and forth and pushed up on the opposite side and it made a trench! It was pretty easy actually.
After a couple of hours, I had gone the entire 125 feet from the garden to the house. I did the entire trench first, then started at the source water faucet and went back toward the garden with the hose. Afterwards, I covered the trench with soil to let the grass grow over it. We figure that the trench is there now so if we want to put in pvc later on, we just pull up the hose and half the hard work has already been done.
Then came the test. As you can see, I put in this Free Standing Hose Stand (got mine at Home Depot, less expensive, but above is link for Amazon). It goes into the ground and you hook up the supply hose at the back and then the front acts as a regular hose faucet. It was the moment of truth..and yes, we did actually have tremendous water pressure! I didn't notice any loss of pressure, it's the same as it is at the house end. It's wonderful, we now have running water in the garden! Yay!
Lastly, I added this four outlet valve manifold. We opted for the brass version for long term durability. I can connect an array of hoses for the various raised beds now. Of course, for this first season, I will probably only use one since we are limiting the veggies to a few beds. Better to plan ahead for the future.
Next I am having soil delivered (hopefully this week), then mulch (hopefully next weekend), then I have to hook up the drip irrigation to the beds we are planting. I say hopefully because we have some rain in the forecast this week...
Update: I've had a couple of comments that reminded me I didn't address everything I should have. The trench is dug to about 4 inches deep, which is shallow. Of course here, we don't have the hard ground freezing other parts of the country might in Winter so I won't ever really have to worry about that. And secondly, I do have a timer that I purchased last year that will go on here so that I can make sure the water comes on and off as needed. :-)
