HONOLULU, August 20, 2018 – Hawaiian Electric will begin construction this week to install new 46-kilovolt cables serving Waikiki crossing under the Ala Wai Canal to make way for dredging of the canal.

The State Department of Land and Natural Resources plans to dredge the canal for flood control and better recreational use starting later this year. Existing 46-kV cables buried under the canal must be removed for efficient dredging. Hawaiian Electric plans to finish its work in early 2019 before the canal is dredged in the area of the cables.

After preliminary work on both sides of the canal, Hawaiian Electric will use horizontal directional drilling to install the new cables in duct lines about 40 feet below the canal to minimize disruption from conventional trenching in city streets. As with any major construction, some short-term impacts are unavoidable. Hawaiian Electric and its contractors will make every effort to limit lane closures, noise and dust. Updates will be issued as available to assist those living in and transiting the area.

Here is a brief overview of the work to be done:

  • Trenching and installing cables from the Waikiki Substation on Kaiolu Street to Ala Wai Boulevard
  • Horizontal directional drilling and installing cables under Ala Wai Canal and Ala Wai Boulevard from Kaiolu Street to Ala Wai Neighborhood Park
  • Trenching and installing cables from Ala Wai Neighborhood Park to Hihiwai Street
  • Installing cables along Hihiwai Street to Kamoku Street and along University Avenue in existing underground ducts

In addition to clearing the way for dredging, the project will help maintain reliable service that is essential for those who live, work and visit Waikiki. Once new cables are in service, the old, direct-buried cables installed in 1956 and 1990 will be removed.
