SHREVEPORT, La. (AP) - Shreveport officials say the cold snap has broken 17 water mains around the city over the past several days. Four broke Wednesday morning.
Extreme temperatures make the ground expand and contract, breaking mains. This past summer, there were more than three dozen breaks at one point.
Lonnie Fouts, an assistant superintendent with the water department, says since temperatures will be below freezing for most of the rest of the week, more breaks are likely.
He says the plastic pipes now used in water systems handle extreme temperatures better than older metal pipes.
