The boil water notice on the Doohamlet Group Water Scheme has been lifted this week.
The notice was put in place in early August after an issue was detected in the distribution system.
However, the notice was lifted by the scheme's management earlier this week.
Meanwhile, Do Not Consume notices remain in place on the Mountainlodge and Billis-Lavey schemes in Cavan.
Levels of manganese were found to be in exceedance of approved levels after testing in recent months.
Notices remain in place on both schemes, with people in the area urged to avail of the alternative water sources available at designated locations.
