Rainfall & Drought

Climate change has brought about a change in rainfall patterns which is generally decreasing rain in formerly dry areas and increasing rainfall in the wet areas. We need to find ways to take advantage of these new patterns by capturing more of the rainfall and diverting it to the dryer areas.

Rainfall Issues

The Aquifers

Much of Hawaii's pristine fresh water comes from its volcanic stone aquifers. The increasing demands for water from Hawaii's increased population and tourist industry, combined with rising ocean levels have shrunk the supply of fresh water in the aquifers, particularly on Oahu.

Groundwater Issues

Rivers & Streams

The flow of fresh water streams and rivers in Hawaii have also significantly declined. At the same time, shrinking government funding has curtailed stream level tests and sampling so the decline is uncharted.

Water Conservation

Water conservation is the key to preserving Hawaii's dwindling freshwater supply. Many mainland cities have successfully used new methods of conservation as part of their future water plans. Water rates need to be utilized which encourage users that are conserving water at the same time as punishing water wasters.
