Auloa Road and Ulukahiki Street: 16-Inch Water Mains Project

Board of Water Supply (BWS) contractor, Nan, Inc., is working to replace approximately 7,700 feet of 16-inch water mains and 300 feet of 8-inch water mains installed from the 1960s.

  • Ulukahiki Street from Kalanianaole Highway to end
  • Loop Road from Auloa Road to pipe bridge over Maunawili Stream
