For a 1 mile run I might consider going up to 3" for the water supply. the larger the pipe, the greater the volume of water that can be carried. A 1' section of 1" pipe holds 9.4 cubic inches of water. The same length of 2" pipe holds 37.7 cubic inches of water. A 1' section of 3" pipe holds 84.8 cubic inches of water. The greater the volume of water that can flow through a pipe, the less effect you will feel when someone uses a fixture. If you run a 3" main to the first two houses, then step it down to 2" for the last house, and branch off of the 3" and 2" main with 1" pipe to run into the house ,everyone on that main will have high water pressure and great volume. But, if you are limited to a maximum diameter of 2" use the 2" pipe.

Go with the 2" pipe by all means. It will flow three times more water than the 1" pipe will. This is a big plus if you're in the shower and someone flushes!!

Go with the 2". I have a home serviced by a 50" length of 3/4" pipe and it isn't enough.

The larger the pipe, the better. I don't think a 1" pipe would be large enough to meet the demand of three houses.

A mile? Thats a whole lot of pipe and digging! 1" over a distance like that, would not be sufficient for 3 homes.
Maybe a well would be cheaper.

One must also consider the RISE in addition to linear distance, the latter being least important. If the application is of the same elevation as the supply source, then a couple of step down systems previously mentioned will most likely suffice. However, it is important to understand the hydrostatic pressure of the vessel itself is of utmost importance. For every foot of rise in elevation .433 psi is subtracted from the original working pressure . For instance: supply pressure=47 psi, actual gain in elevation at 3 houses 100 ft. ...........47psi - (.433x 100)=4psi at 3 houses.

it depends on what kind of area you live in and if its for hot water or cold water, for hot water i'd run galvanize pipe 2", if its cold water use pvc but only if its for a draining purpose 2", or for cold again 1" galvanize pipe.

u need a 4" for that span.....and reduce it to 3" half way and 2" 3/4 way......this will supply volume and pressure for the services.......

FIRST nathanael--bigg-dogg and stratman all gave you good answers---NOW-- call a contractor who will look at your specific need and give you the proper info---this is too major a project to undertake without pro. help.
