Water Pressure Problem

I own a 3 story building with six apartments. The water pressure has never been great and know that I have a families living in the lower floor apartments, the water pressure is often so low that you can not take a shower in the third floor baths. I had my plumber check the pressure coming into the building and I am getting 40 lbs which he says is normal for Brooklyn. Any ideas on how to improve the pressure and get more water to the upper floor? I’ve heard that booster pumps exist – has anyone actually put one in?
