No, low pressure in the mains is very problematic. Normally the pressure is high enough nothing can get in. When the pressure is too low stuff can mix in. The water mains are not hermetically sealed after all.
Low pressure is caused either by a lack of pumping ability or too much water flowing out. As several places have frozen, likely the latter.
None of this is a surprise to people who know these things.
