Irrigation system

I rigged an irrigation system using a sump pump that I had, along with a generator I had on hand. I drilled a bunch of small holes in a salvaged plastic barrel for a pre filter, then dropped the sump pump and the barrel in the creek. I used a nylon rope to keep the sump pump turned on. I hooked the pump to a garden hose to the drip irrigation filter then to the spagetti tube. The spagetti tube is normally inside the drip tube but I pulled it out for the picture. I had 5 rows of drip tape about 150 feet long on this system. In the early season there wasn't a need for the irrigation but when it got dry, the system should have run 4 or 6 hours each day. I didn't manage to run it enough but what I did was certainly worthwhile. I realize sump pumps are not designed for irrigation. There was less than 10 feet of head and the drip system is designed for 10 lbs of pressure but will work on slightly less. Any more head or any more drip lines and the system probably wouldn't have worked. I also realize there was a lot of wear and tear on the generator. (I intend to replace the generator anyway. It doesn't have a plug in to run my 220 volt well. ) However, I got a lot of value for the actual money I spent.
