Bulk water supply

SetRatioSize300225-Healthboy.sized

Every day the people of greater Wellington have access to high quality drinking water at the turn of a tap; summer or winter, it's always there. A safe and reliable water supply is vital to the health and prosperity of our region. 

Greater Wellington collects and treats all the tap water used in Lower Hutt, Porirua, Upper Hutt and Wellington.  Once it's treated, we distribute the water to reservoirs owned by the four city councils, from where the cities supply to the public.
