A bit more info would help us to help you even more. How much watering do you plan to do with this water supply? Drip irrigate or 20 sprinklers at the same time? The volume you need will greatly affect what piping you can get away with. Also, I'm assuming this is just for irrigation, not potable use? And lastly, I'm assuming you don't have much of a problem with frost in the ground...
Mike Jay wrote:Good, then it sounds like we have a possible option for you. Once you know your gallons per minute you can figure out if you even need to go bigger than an inch in diameter. Just to clarify on my set-up, the pipe is only pressurized when the pump is running (10x per year). So it does not experience pressure all the time. But I can't imagine that it couldn't handle it. It's very tough. I'm kind of surprised a coyote could bite through it... Can you get to the tank to open a valve on days you want to water? That would relieve some anxiety about losing all your water in the case of a failure.

Do you have power at your water tank? Finding a large diameter timer valve that doesn't require power or water pressure will be a challenge. Most watering timers that you put on garden hoses rely on the city water pressure to help them actuate on and off. There are solar powered timer valves that don't need water pressure but they are more like 3/4" in diameter.
permaculture is a more symbiotic relationship with nature so I can be even lazier. Read tiny ad:
