FAQ about water
What's the best water filter for tank water in New Zealand?
The right filter depends on what’s in your water. For most NZ rainwater tanks, a whole-house sediment filter combined with a UV system is the safest and most effective combination. The sediment filter removes particles, and the UV kills bacteria. We recommend getting your water tested first, so you’re not over- or under-treating it.
Do I need a UV filter for rainwater?
If you’re drinking from a rainwater tank, yes. UV treatment is the most reliable way to kill bacteria, including E. coli and Giardia, without adding chemicals to your water. It’s low-maintenance, has minimal running costs, and is widely used across rural Rodney. The lamp needs to be replaced annually to remain effective.
What's actually in Rodney district tap water?
Mains water in the Rodney area is treated with chlorine and chloramine to meet NZ Drinking Water Standards. Some areas also receive fluoridated water. While it’s safe to drink untreated water, many homeowners choose to filter out chlorine taste and odour, particularly for drinking and cooking. Silica scaling is also a known issue in areas like Snells Beach.

How do I know if my bore water is safe to drink?
You can’t tell from looking at it. Bore water can look and taste fine while carrying bacteria, nitrate, iron or manganese. Bacteria are more likely in shallow bores and where the bore head isn’t sealed properly, and iron bacteria can be a real problem too. The only way to know is to test the water. We can advise on testing and, once you have results, recommend the right bore water treatment. Don’t assume bore water is safe without testing, particularly if you have children or elderly people in the household.
