low water pressure

I have low water pressure now that I have extended a water line to my shop. My pressure at the pmp is 55psi. i am running 250 ft with a 3/4 in pvc pipe. Any suggestions on my problem or what I can do.

The 250', of 3/4" PE pipe might have worked but, any pipe or tubing using couplers every 10-20' is not going to give much water flow because of the pressure losses.

Is the line flat or does it go up/down hill to the shop? If up hill, that's more pressure loss; like .422 psi per foot of elevation.

And if you have a jet pump (above ground)... they usually aren't going to work too well for this type application. Especially when the house is using water when you want water in the shop.
