Hawaii Market

The Hawaii water systems, well service and well repair market is niche with numerous barriers to entry. First, the remote geographic project locations present product delivery challenges from manufacturers and logistics. Further, contractor’s licensing requirements, local acceptance in the marketplace, limited availability of skilled craftsmen, and access to pump manufacturers’ product lines make it difficult for new entrants to compete in an already well-established marketplace.


WRI’s customer mix is roughly 50% Municipal and County Governments and 50% private industry, commercial, industrial, agriculture, golf courses, etc.

The following is a partial list of WRI’s major customers:

  • Board of Water Supply, City and County of Honolulu
  • Department of Land and Natural Resources, State of Hawaii
  • Department of Water Supply, Hawaii County
  • Department of Water Supply, Maui County
