Fleming-Neon's municipal water system was 90 percent back online Monday, but water went out over the weekend to customers on the Letcher County Water and Sewer system.
Water line breaks on Saturday took out water service to large portions of the county system's 2,500 customers. Water was restored to about 500 Sunday night, Judge-Executive Jim Ward said, but another break slowed work.
Ward said he hoped to have service restored to most customers by midnight. All Letcher County Water and Sewer District customers are on a boil-water advisory until lines are flushed.
The Fleming-Neon city system lost water Friday afternoon because of a shortage that clogged filters and stopped flow at the treatment plant.
The system's 1,150 customers are on a boil-water advisory, and there is still a shortage because of summer drought conditions, but service has been restored to most of the system, said city worker Charles Sergent.
