Consolidated Water, a leading designer, builder, and operator of advanced water supply and treatment facilities, has announced a key development in its $204 million seawater desalination project in Hawaii. Its wholly owned subsidiary, Kalaeloa Desalco, recently secured a critical approval from the Honolulu Board of Water Supply—the client for the multi-year initiative that began in June 2023.
The Board officially approved the pilot test reports and recommendations submitted by Kalaeloa Desalco, confirming that the desalinated water produced during the piloting phase closely matches the quality of the region’s existing water supply. Additionally, the Board determined that the new water source would have no adverse effects on current distribution infrastructure or customer assets.
“This significant project milestone helps pave the way to begin construction once all permits have been obtained,” said Rick McTaggart, CEO of Consolidated Water. “The construction phase is expected to drive the majority of the project’s revenue and serve as a major growth engine for our services segment in 2026 and 2027.”
The project includes a two-year development phase, followed by two years of construction. Upon completion and commissioning, Consolidated Water will operate the 1.7 million-gallon-per-day desalination plant under a 20-year operations and maintenance (O&M) agreement, with two optional five-year extensions at the client’s discretion.
