The city of Jackson, Mississippi, is struggling to return pressure to its water system, after issuing a citywide boil water notice, the city said in a Monday morning update.The troubled system lost pressure due to line breaks likely caused by the weather, according to an earlier statement from the city.“We are producing significant amounts of water and pushing that into the system, but the pressure is not increasing – despite those efforts at the plants.”The city asked residents to, “refrain from reporting pressure loss,” as it said it’s, “well aware of the system pressure issues.”The notice follows widespread problems in the fall with water pressure and brown water spewing from faucets and in toilets.City officials said crews are working to find and repair the line breaks from this Christmas weekend, and are working with the federal Environmental Protection Agency, the update added.The city asked citizens to turn off running faucets on Sunday afternoon while temperatures are above freezing."
