UPDATE: The broken water mains that left parts of Walker County with low or no water pressure Thursday has been fixed as of about 1:00 p.m.

Residents at higher elevations may have some trouble with a lower water pressure until tanks are refilled.

The breaks are being attributed to the drought that's affected most of the Tennessee Valley this summer.

The general manager at Walker County Water and Sewage Authority, David Ashburn, said when the drought becomes this bad, the earth hardens, shifts and cracks, which can cause water lines to crack as well.

PREVIOUS STORY: Ashburn tells Channel 3 that the  Mission Ridge water line issue has been fixed.

Lines are being flushed to clear any dirt that may be inside. Residents should have water again before noon. Between 800-900 homes were affected by the problem.

A separate issue on Happy Valley Road is still waiting to be repaired.

Utility crews will need to mark off utility lines in the area before work can start. The legal requirement is to keep everyone safe and prevent secondary outages. Officials say there is a gas line nearby.

It will take three hours to fix the problem once repair work starts. This line only impacts a few homes, but also Ridgeland High School.

PREVIOUS STORY: According to the Walker County Water and Sewage Authority, the Mission Ridge road area is experiencing a water main break. Customers may experience low pressure. 

This affects the community of  Fairview, including Wilson Road, Happy Valley road and possibly additional areas. 

Officials do not have a time for when water will be returned to normal conditions.
