poor pressure

I am soon to be working on a large 15k sq ft older home..I do not know exactly what the supply size is..most likely 3/4 to 1 inch...multiple showers..sinks..toilets..the main complaint is low pressure at the fixtures..It appears that the sysrem has been worked on many times..most supply is copper..my question is..if this is all the pressure I will get from the city to the house is there a booster pump that will handle the entire house or will I need to install multiple boosters..and can you install multiple boosters??

You have no idea what the reason for the low pressure is, so how can we, you, or anybody decide how to cure it. Call a plumber and get an evaluation of the problem. It may have nothing to do with the pipes or city pressure at all.

One thing you should do is to determine if you have a pressure problem or a flow problem. If you still have galvanized pipe, that could be corroded to the point that you can't get enough flow. A pressure gauge can be obtained at any hardware store.
