Water System Source

Hanalei

Where does my water come from?

Your water comes from ground water (underground) sources.  Rain that falls in the mountain filters through the ground into formations called aquifers. Wells are drilled into these formations and the water is pumped out. These formations can also be found in the mountains (still considered ground water). Tunnels are constructed to tap these sources. 

The quality of groundwater is very good and requires no treatment except for disinfection (as opposed to surface water sources that require filtration and stronger disinfection).

The water supply for the Hanalei water system comes from the following sources:

            Maka Ridge Well (No. 73)

All of the water is chlorinated and pumped into the distribution system or stored in the following tanks:

            Maka Ridge

            250,000 gallon tank

            Hanalei

            50,000 gallon tank
