#water conservation

As parts of Maui County continue experiencing drought conditions and with warmer temperatures expected to increase water use this spring and summer, Hawaiʻi Water Service (Hawaiʻi Water) encourages its Maui customers to take advantage of conservation resources to help them save water—and money.

Council Chair Alice L. Lee reminded Maui County residents that the county’s new water-conservation ordinance took effect last month, emphasizing that responsible water use remains critical despite recent heavy rainfall.

A disturbance approaching from the northwest is expected to renew deep tropical moisture across all Hawaiian Islands beginning late tonight.
