JACKSON, Miss. (WJTV) - JXN Water officials said the city has 100 miles of undersized pipes throughout the streets.

During JXN Water's quarterly meeting on Saturday, Interim Third-Party Manager Ted Henifin said they're not replacing the whole system. However, two- and four-inch diameter pipes will be replaced with six-inch PVC pipes.

“Those small pipes have a lot of rust in them as the pressures change, and they get disturbed. They do become brown water. It has iron in it. Not hazardous, but certainly not something you love to have in your glass when you're serving your friends," said Henifin.

Crews finished one-mile of new pipes in a South Jackson neighborhood. Henifin said they have two more miles ready for bid, and he expects the project to be out for bid within the month.
