Hala‘ula Well Development Phase II | Kapa‘au, Hawai‘i


Kapa‘au is a small town located on the northern tip of Hawai‘i Island. In early 2008, the county water board dug an exploratory well in Kapa‘au with plans to eventually add more capacity to the existing water system. However, the project was put on hold for more than a decade. To the relief of Kapa‘au residents, the project was resurrected and put out to bid in 2018. GBI started working on the Hala‘ula Well Development Phase II project in December of 2019.


GBI’s scope of work included the installation of the pump and motor for the well, construction of a control and chlorination building, and a 500,000-gallon cast-in-place storage tank. Additionally, GBI replaced 15,000 linear feet of asbestos concrete pipe with ductile iron pipe, replaced more than 120 service laterals and a dozen hydrants, and connected the new system into existing ductile iron services on both ends of the line. The newly constructed well and storage facility adds much-needed capacity to the community’s water system and serves as a backup for the nearby Hawi Town system if one of its wells were to fail. GBI is proud to have been a part of this project, which has not only helped modernize Kapa‘au’s aging infrastructure, but has also contributed to the health and well-being of local residents.
