A very long run from the meter.

Always, in fact one friend of mine uses his "cold" water for hot water and lets the water in the heater, which is turned off, cool to room temperature and uses the "hot" side for his cold water. PVC is perfectly acceptable for potable water, it just cannot be used inside homes as a "water damage" prevention standard. I am sure at least 90% of the homes in this area have PVC lines from the meter to the house.

It probably be more like dig a foot big rock, dig 6" then very big rock, then dig a foot then a really big
boulder that you have to go around, a good ideal to have a backhoe

I not looking for a complete answer from a forum. I'm certain that there will be a good bit of research before I can do this. At this point I don't know how much I don't know.

This forum has already been helpful, but finding info that applies to my situation is tough. Is there an online place I can go to learn this without having to search all over a forum? That way you only have to answer that first question :D .

The senario:

We are soon to be closing on a 10 acre property near Alton, MO. Very fortunately it has rural water. Oregon County PWSD #1.

Eventually ( in a couple years ) I want to run water to the back of the property which is just under a 1/4 mile. Call it 1200 feet. Optimally I'd like it to serve 2 bathrooms, washer, dishwasher, outside hydrant. Normal stuff for a 3 bedroom 2 bath house.

Immediately I'd like to run the water to where we plan to have temporary housing about 500 feet from the meter. Temporary as on a singlewide or large camper.

My questions:

If someone has the time..... can you give me a ballpark idea of:

Is it possible? 500 feet? 1200 feet?
(500 feet I think yes..with 1.5" pipe. https://terrylove.com/watersize.htm)

Pipe size? (I think the PWSD guy said 2" pipe. Blame me not him if wrong)

Pipe material? (It's a long run I quessing it will cost about a billion dollars.)

I have been advised to go 18" deep...?

How do trees affect where to run the pipe?

Is there something that can be placed near the meter that will shut off in case of failure of the downstream pipe?

What do you suggest so that the 500 foot run I put in now will also be usable for the 1200 foot run later? Or, that not even a reasonable idea?

Thanks in advance. Any help would be,.... Helpful.
Your line is only as good as the line to your meter. In other words if your line from the main to your meter is 1 1/2” putting anything larger than that going out of your meter is not going to increase your volume or flow of water.
You can come out with a 4” line and you would still have the same results as an 1 1/2 line.

Maybe it's best not to revive an 8 year old thread, but that's not exactly true.

If you are connecting to a large water main, it's close to being a constant pressure source (the pressure will drop a little with large flows, like 100 gpm, depending on the details of the utility's piping system). Everything between the water main and your water outlet will contribute to the pressure drop; each component (including the outlet) will have its own pressure drop versus flow curve. The system as a whole will flow at the rate for which the pressure drops for each component add up to the available pressure at the water main.

A pipe's pressure drop with flow will vary linearly with the length, and at about d^(-4.87) with interior diameter (Hazen-Williams). In other words, 1' of (exactly) 2" ID pipe has the same pressure drop as about 29' of (exactly) 1" ID pipe (of the same material).

So say you have 20' of 1-1/2" pipe from the water main to the meter, and then a 200' run from the meter to the house. You'll have greater available pressure versus flow at the house if that 200' run is 2" than if it is 1-1/2". The 20' of 1-1/2" will disproportionately contribute to the pressure drop when the 200' run is 2", but it's not in the form of a hard limit.

Hey, wait a minute.
