A water main break this week caused brown tap water for some South Orange residents, the East Orange Water Commission said.

The fault was fixed on Thursday., according to Thomas Valenza, the general supervisor of the commission.

Valenza said he was unsure exactly when the main break occurred, but the commission received word of the problem on the morning of March 3 and it was repaired later the same day.

A forum on the Maplewood/South Orange message board revealed residents began noticing brown tap water on Feb. 28. Valenza said, that only residents in South Orange should have been affected, as that was where the main break occurred.
