City water connection - can they make a connection at a hose bib?
I doubt seriously that the city crew would connect your water supply to a hose bib no matter what you told them. It is just too far outside of the norm.  For one thing, If you live in a climate that experiences sub-freezing temperatures in the winter your pipes would freeze and burst.  Virtually no one does it this way.  you want a good deep ditch between the house and the water supply to lay the pipe in, below the frost line.  Enter the house through the foundation wall below the frost line and connect to the cold water line at a good and convenient location.  In the years to come, you will be glad you did. (In an emergency and for a short period of time, yes you could connect to the hose bib.  It would work.)
