Hawaii Water Service is a utilities company serving water and wastewater customers in Hawaii, with a history that includes the acquisition of Ka’anapali Water Corporation in 2003 and later expansion through purchases such as the Pukalani Sewerage Treatment Works and multiple Waikoloa utilities. Its operations span Maui and the Big Island, managing regulated accounts for residential, resort, condominium, hotel, golf course, and commercial customers, including several large users. The company operates within California Water Service Group as a subsidiary, and its activities encompass providing essential water and wastewater services to communities and properties across these regions. Based in Waikoloa, Hawaii, the company has grown through a series of acquisitions to broaden its service footprint and customer base, now serving thousands of accounts across Maui and Hawaii. A recent development indicates Hawaii Water Service engaging Carollo Engineers for a feasibility study on a decentralized wastewater treatment plant in Kapalua, intended to support recycled water production and drought-resistant irrigation supplies.
