Rain water is filtered through sands and gravels and seeps into the deep Waimea aquifer, which provides natural underground storage. In times of low river flow, water from the aquifer will be pumped and discharged into the river downstream of the Waikanae Treatment Plant intake.
This means the taste and quality of the water that comes out of your taps will not be affected by groundwater being added to the river, as it will not enter water supply.
As well as enabling consistent high quality water, the consented extra extraction allowed secures supply for future growth in the Waikanae, Raumati and Paraparaumu areas until 2048.
