Dole St. was reopened around 6:30 a.m. Sunday after crews finished repairs to a 20-inch water main that broke Thursday afternoon.
Service was restored to the main about 7 p.m. Saturday, the Board of Water Supply said. No customers were affected during the repair.
The main break happened near the University of Hawaii Center for Hawaiian Studies building around 2 p.m. Thursday. Air conditioning and water service were affected on the upper campus and student housing. The main break also affected water service to other customers in Manoa, St. Louis Heights, Makiki Heights and Lower Makiki.
Dole Steet was closed in both directions between Kanewai Park and University of Hawaii Faculty Housing until sometime Friday.
At 5:45 p.m. Thursday, the Board of Water Supply isolated the damaged portion of the 20-inch main and pumped water into the transmission line on either side of the break to restore water service to customers.
The main was installed in 1928.
