Most metropolitan water supplies fall within these limits. If sludge or foreign matter is present in the
water supply, a suitable filter should be incorporated in the water supply.
Some examples of water quality issues where water may need to be treated:
•
Hard water (areas including Whanganui)
•
Aggressive water (areas including Christchurch)
•
Both hard and aggressive water (some bore water)
