Our ‘Ewa Beach fifth graders have been studying all things water. Fresh water, that is — the water we need to live. They visited the Board of Water Supply’s xeriscape garden in Hālawa to learn about O‘ahu’s water supplies. Uncle Arthur talked about BWS plans to recycle and desalinate so we can meet our future water needs. Conservation is also important, and students toured the xeriscape garden, which is planted with native and dry-climate plants that help reduce the amount of water used outside.
DID YOU KNOW?
All of O‘ahu’s fresh water comes from rain that falls on our mountains. It takes 25 years to filter down through the porous volcanic rock before it reaches the underground aquifer, which is where all of our tap water comes from.
