The Department of Water Supply announced completion of the Palani exploratory well drilling, approximately 700 feet south of the Kaloko boundary at the 1,700-foot level.

A pump test is expected sometime next week to determine the well's safe yield.

The test will last at least 96 continuous hours, and compressors and engines will be equipped with industrial silencers to minimize noise, officials said.

Although it's a private project, the well will provide significant water capacity beyond the needs of the private developer, benefiting the North Kona community, according to the county.
