At least, it's not guaranteed your water company will be able to continue to operate without electrical power. If you've saved water for emergencies, you can usually keep chugging.

After Cat 5 Hurricane Michael we did not have water except the water we dipped from the pool. So much of the power infrastructure was out and fuel could not be pumped so the water company could not operate their pumps. And even with their backup generators they could only operate a couple days until their fuel ran out. Neighborhood booster pumps needed to be serviced one by one. Most were buried with debris.

It took about a week to restore things to my house.

After Cat 4 Hurricane Matthew in Puerto Rico (the year before) it took them at least 3 months to restore the first neighborhoods. The difference - in Puerto Rico, which had the highest electricity rates in the country, the power company was government owned and the workers got paid whether the power worked or not. In my neighborhood, the power is delivered by a private company - Florida Power and Light (now part of Duke Energy).
