Increase Fresh Water Capacity
In 2013, Hawai‘i’s statewide water demand was 449 million gallons per day (mgd). Using this figure as the baseline, coupled with projections for population increase, it is estimated that 100 mgd of additional fresh water capacity* is needed in order to meet Hawai‘i’s future water demands without extracting more valuable groundwater resources or resorting to high cost alternatives such as desalination. To achieve this ambitious goal, key stakeholders across the public, private, and philanthropic sectors must work together on conservation, reuse, and recharge initiatives.
* Fresh water capacity refers to the amount of water available for consumption, and can be defined as the total decrease in water demand combined with the increase in water supply.
