About Us

Napu'u Water, Inc. (NWI) is a member owned non-profit organization. The company was incorporated in 2005 and began supplying water to its members in 2006. Two wells (each approximately 2,500 feet deep) draw water from the Kiholo Aquifer to provide water to the community in Pu'uanahulu, Pu'u Lani Ranch and Pu'u Wa'awa'a.

The water NWI delivers to its members is of superior quality as documented in the annual Consumer Confidence Report (CCR). Click the link below to view the current CCR. CCRs are updated every year by July of the year after the year reported as required by the Safe Drinking Water Act.
