Chlorine & Health Protection

Chlorine is added to treated water at the Joyce Road and Oropi Water Treatment Plants to kill germs in the pipes which carry the water to your home. This practice is widespread in New Zealand and many other countries and has been done for decades for public health purposes.

Some promoters of home water treatment devices use emotive language to scare people into purchasing their products referring to chlorine as a "poison".  Do not be alarmed!

Tauranga has one of the highest levels of water quality rating (Aa) from the Ministry of Health.  The microfiltration systems at the Joyce Road and the Oropi Treatment Plants provides a physical barrier against Giardia and Cryptosporidium to keep them out of the water supply. 

Some people object to the taste of chlorine in water.  Most, if not all of the taste, can be removed by boiling the water for five minutes.  Keep it uncovered in the fridge.
