Where does my water come from?


Your water comes from ground water (underground) and surface water sources.  Ground water comes from 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. Tunnels are constructed to tap these sources.  The quality of groundwater is very good and requires no treatment except for disinfection.  The surface water source is the Kapaia Reservoir.  The water is pumped into a filter plant to remove all the suspended material from the water.  The water is then disinfected and fed into the distribution system.
