Low water flow to whole house

[cmolina524]

I have a pressure reading of 75 psi to my house but the flow is very poor. We do not have a water softener or pressure regulator. The flow is about even on hot and cold taps. We ran a 5gal bucket test and after over 1min we were not even at half. This started about 1 year ago and has gradually gotten seemingly worse. On our 6 sprinkler heads only about 3/4 raise up. Had the city come out and said since we dont have a problem with water pressure there is nothing else they can do. Need advice on what it could be. Thanks.
