Ideally the water department is correct. If pressure at the main valve is the same as the mains pressure then the problem lies in your internal plumbing. from the main valve you should have 3/4 inch as a feed and where you tap off for fixtures you use a 3/4 x 1/2 x 3/4 T. Same for the hot water heater. Come off the tank with 3/4 and distribute with 1/2".
