Would a 2" PE waterline be sufficient?
(OP)
For an 8 unit development spread over max Length of 3000lf.
Also, anyone know what the normal flow should be for a home w/ 40-60psi?
Thanks in advance for any help.

RE: Would a 2" PE waterline be sufficient?
They just want water to their homes. Thats all. I was thinking to put in a 4 inch line but it'll be hard to get all the materials to this remote area. So I'm trying to see if a 2" PE line will serve 8 homes. Its easier to transport the 2" PE then a 4" PVC.
Thanks for any help you can give.
I dont currently have a software that will run the numbers for me so if you have a free one I can use, please let me know.
RE: Would a 2" PE waterline be sufficient?
Don't forget to account for any elevation changes as well.
Would youi consider twin 2" PE lines? Not the capacity of a single 4" but perhaps more feasible. If you go with two lines be sure they can be isolated so that one can be taken out of service while the other remains in service. Probably relatively cheap to add four valves vs the inconvenience of someday losing service all together. On the other hand, what damages one line may well also damage the other.
Another thing to consider would be to add an elevated storage tank, perhaps a few hundred gallons, to account for usage surges. Depending on how you size this you may find that a 1.5" pipe will do.

Their is an existing water tank on the side of the hill about 130 feet in elevation difference from the lowest home and about 50 ft elev. difference from the nearest home.
All homes are downhill from the tank. We'll be installing some small pumps in the homes to increase pressure due to the lack of pressure from the tank.
I guess we'll go with a 2" PE line and go from there.
Thanks again for your help.
RE: Would a 2" PE waterline be sufficient?
since you will be drawing water off at intervals along the 3,000 feet, you will have considerably less pressure drop than previously suggested.
Plan on something like 100 gallons per day per person. more for irrigation, possibly less on the reservation due to low usages. I think the 25% usage factor is probably the most likely.
for water quality and for reliability you should consider a loop. This would also greatly reduce the pressure drop.

It's not that different than the fact that most bathrooms, even brand new ones, only carry 2 outlets per sink, yet, we have so many more bathroom appliances than even, so we wind up adding socket capacity, ala power strips, to power radios, dryers, shavers, toothbrushes, etc.
