The majority of water use on the island comes from agriculture
Maui, Hawaii, has begun public hearings on a new draft of the island’s water use and development plan, which has not been updated since 1990. The plan guides the management and use of water across the island.
The new plan specifies that the island has enough water to meet current and projected uses for the next 20 years, but that water resources are not always located to best meet needs, as reported by The Maui News.
The island has approximately 833 million gpd of surface water, groundwater and untapped groundwater, with approximately 500 million gpd used on average. The majority of water use is in agriculture, according to the draft.
With the island’s groundwater total sustainable yield at 427 million gpd divided among six aquifer sections, water distribution could be a potential problem. The island’s largest population center is in the Central Maui aquifer, which also has the lowest sustainable yield of 26 million gpd, so water supporting this area may need to come from elsewhere on the island.
After the public hearing process, the draft will require approval by the Maui County Council and the state Commission on Water Resource Management.
