Wouldn't it make more sense to add the chlorine after the water is drawn from the reservoir? Doesn't that fix the bromate problem at the root?

- rtpg 11y agoJust a guess, but maybe chlorine needs a good amount of time to be effective, and the transit time from reservoir to tap might not be enough
- Zardoz84 11y agoWhy not use ozone to teat the water. It's a better solution that chlorine, even more effective to kill bacteria.
- david_b 11y agoWhy not, indeed... Bromates are formed many different ways in municipal drinking water. The most common is the reaction of ozone and bromide. Source: https://en.wikipedia.org/wiki/Bromate https://en.wikipedia.org/wiki/Bromate
- PhasmaFelis 11y agoI would guess that having loads of dead algae in your drinking water is not much better than live algae. You want to keep assorted gunk from having a chance to grow in the first place.
- zz1 11y agoBut certainly the water is filtered before reaching homes, considering it rests a long time in a open reservoir. So you could remove the dead algae. Still, they certainly have a "better dead" approach, wanting the reservoir to be a dead pool instead of a living ecosystem where they'd have to monitor what is growing and how dangerous it might be.
- DanBC 11y agoIt's interesting to compare different systems. Here's one for a small part of the UK. Our tap water (from thefaucet) is vety high quality. http://www.thameswater.co.uk/cycles/accessible/water_treatment.html http://www.thameswater.co.uk/cycles/accessible/water_treatme... The last stage of the process is to add chlorine to the water.
