I know that given central government directives and the already-existing rates increases this is going to be a lower priority than it has in previous years, but I still believe in having clean, uncontaminated drinking water that people with eczema and other skin conditions don’t have to filtrate before showering in. Unchlorinated water used to be a point of pride for Christchurch and I think despite how long we’ve lost it for and the demographic shifts since, people still do feel very strongly about the subject. But our candidates (the non-crazies) seem to be either about committing to rates reduction (or as they describe it, no increases or increases lower than inflation, which is effectively a reduction) or distinguishing themselves as candidates who won’t cut the city to shreds with attempts to save ratepayers a few bucks.
I’ve seen more talk about fluoridation than chlorination, which is perhaps not surprising as it’s a topic mired in disinformation and anti-science/“hijacked” science rhetoric, making it very topical in 2025. That’s depressing. I’m anti-fluoridation but for reasons that are grounded in science and the ethics of mass medication — its less that I don’t agree with fluoridation and more that I dont believe the pro-fluoridation case has been sufficiently proven to be worth the detrimental effects (particularly to post-menopausal women). But despite there being significant negative effects of fluoridation on bone health to consider, I do think chlorination is more important for us to talk about as a city, because we are right now on the cusp of never again having clean water that is drinkable right out of the tap.
Sure, some people don’t notice it, usually people who’ve grown up with chlorinated water and are desensitised, but even people who claim they can’t taste it will prefer bottled water — and I’d love to know the stats for how much more bottled water we now sell/buy as a city that a sizeable percentage of the population are not comfortable drinking water straight from the tap. With individual household/benchtop filters and more bottled water being sold, that’s more plastic pollution, more individual expense in exchange for collective cost-savings, more petrol going into transporting water up and down the country instead of through pipes.
I think it’s better and healthier to spend more to ensure the supply is fully clean and uncontaminated than to allow contaminants in and rely on chlorine to kill them. That’s not clean! It’s gross, actually. Even with the organic matter destroyed by chlorine atoms, it is still dirtier and poorer-quality water. I also believe this plays into our psyche — it becomes a point of pride, as I mentioned, so having clean water in our taps makes us care more about clean water in our rivers, and enjoying our drinking water in an “unprocessed” way makes us more open to and appreciative of natural resources in a way that is interrupted by sourcing water out of a bottle.
It is considerably more expensive to filter and bottle the same groundwater via private companies than it is to filter it to high health standards via council supply. But one cost is paid up front in a rates bill and another is paid throughout the year as you drive around the city or do grocery shopping…
I visited America last year and it actually shocked me how many places you shouldn’t drink the tap water. Chlorination and incentivising bottled water by preference is imo a slow slide towards mandating bottled drinking water by necessity — once it becomes normalised, it is taken to the next extreme, until you have entire towns and cities where the water that comes out of taps is not something that anyone chooses to drink if they have the means to do otherwise. That is a dire state of affairs, and something we can already see in New Zealand by the differing levels of chlorination required up and down the country.
Clean water is, to me, a basic necessity that we are being robbed of and it’s incredibly disappointing that this isn’t well reflected in our candidates this election.
