If you are on city water, a large pipe has burst somewhere causing pressure to drop drastically. If you are on a well, a problem has occurred in your pump, or your pressure tank, or the main pipe between well and house. In extremely cold weather pipes from a well can burst. Many well heads (at least in my area) are very inadequately protected.
House water pressure should be around 50-60 psi.
You have to undo the aerator at the end of the faucet and clean the screen or plastic water saver out. It will be plugged with sand or sediment.
There may be a number of causes. First, check your PRV and see if you can adjust it to higher pressure. This is usually easy and may solve your problem. If new construction has gone up nearby, mains pressure may be lower. Also remove and clean all aerators and see if that makes a difference. Many people totally ignore this basic step.
under the entire house unless there is a basement....
The water people turned it off incase of leaks

I would purchase a Watt water pressure guage from your local home improvement or hardware store and check your water pressure at your faucet. If water pressure is greater than 40-45psi your regulator needs to be turned down where the water comes into the house.
Sounds like a bad/failed water pressure regulator.
