Water line help?

I am not a plumber nor do I play one on TV but I used 20' sections of sch 40 PVC on the last one I ran 20+ years ago. The better grade of black poly in 100' rolls should be less expensive and work fine. There may be better products on the market by now. Maybe some of the more knowledgeable folks will chime in.

Any of the above is suitable for water supply and poly is likely most practical if allowed by that jurisdiction. Pipe size is dependent on available pressure at the tap and how many fixtures being served. At that distance any thing less than 60 psi won’t give much pressure inside the building unless adding a boost pump.

I have a roll of black poly that I probably never use.

Sure wish it was like that here!!!  Our water authority, mandates, 1" copper for a house, 4' deep, frost line, in sand, 2 inspections, tape in fee, total for my place, 75' plus or minus, with a plumber, that has to be a Master by code, about $12k.

Blue flexible coil , not exactly sure of the name . Basically CTS (Copper Tubing Size) flexible water line . PEX more or less . Several types of pex tubing . Upsize as much as you can afford . 1 inch would most likely work for your application . If it was a new Big house I would suggest 1,1/4" or 1,1/2" for that length . Contact a local "water meter supply company . Locally I go through Illinos Meter Company IMCO. I know they have 400 ' lengths , maybe longer

Around here you can have 5gpm at 25-50ft —— I would also consider having a well put if I needed to run 1400ft length. You said from the road, guessing could be a reason for that? I put sand over mine to keep from any serious punctures from sharp rocks. I bought rejected c32(or 33?) from the quarry at 10$ a ton. And as said, use the brass barber fittings with SS couplings and check the screws.

Blue tuff tube. We’re 1100 feet from the well. Buried it in these Arkansas rocks 20 years ago. One section was on solid rock crossing the creek. Froze several times over the years. Never split or leaked. 3 years back I hired an excavator with a hammer on the excavator and got it buried 3’ deep. Across the creek. Never had a leak in 20 years.

When the gas co. pup in the natural gas line a few years back they used a yellow plastic line with the trace wire molded into to it.   Since it was plastic it will probably last forever.  I don't think I would use yellow tho, as I think that indicates "GAS".  When I've seen water lines being installed the pipes are a blue/green color.  This leads me to believe there is a standardized color code for what is being installed.  It sounds like you are connecting to a municipal water source so I would think you should contact them to find out what they require be installed and any other specs they may require, probably depth would be one.

I get a kick out of you guys drilling a new well rather than run 1500 feet of pipe and ditch. Neighbor dug me one at cost and it was $6 to 7000(250 feet deep). I had a quit for $30,000 from another. 

We just had a local well driller put one in for 2500$ a few years ago. Guess it depends what they want to charge. Needed a trench dug to move power back to my place(300’), I had quotes up to 8k. I bought a backhoe. I figure it can be sold when I’m finished with it for somewhere near what I paid and do several other projects to boot.
