Weekslong boil water notice lifted in Mississippi capital

Emergency repairs are still underway after problems at Jackson’s main water treatment plant caused most customers to lose service for several days in late August and early September.

Problems started days after torrential rain fell in central Mississippi, altering the quality of the raw water entering Jackson’s treatment plants. That slowed the treatment process, depleted supplies in water tanks and caused a precipitous drop in pressure.

When water pressure drops, there’s a possibility that untreated groundwater can enter the water system through cracked pipes, so customers are told to boil water to kill potentially harmful bacteria.

But even before the rainfall, officials said some water pumps had failed and a treatment plant was using backup pumps. Jackson had already been under a boil-water notice for a month because the state health department had found cloudy water that could make people ill.
