| 1424463 | 2016-08-15 03:51:00 | I can't believe the council allows filthy water - not just Hastings, Napier - other districts too. I thought they ALL chlorinated these days. It's what stopped people dying of cholera. The should take lessons from Warecare: The majority of Auckland's water comes from 10 dams in the Hunua and Waitakere ranges. It is treated at four water treatment plants: Ardmore, Huia, Huia Village, and Waitakere. Raw water, which contains contaminants ranging from large debris to micro-organisms, undergoes a series of treatment stages to ensure the requirements of the Drinking Water Standards for New Zealand 2005 (revised 2008) are satisfied. Step 1: Screening Water first passes through ‘screens’ that remove any large debris such as leaves, branches, rubbish, and dead insects. Step 2: Coagulation To remove the dirt, a compound known as aluminium sulphate (alum) is mixed into the water. This makes the tiny dirt particles stick together or ‘coagulate’. The water is then piped into settling tanks. As the alum and dirt particles stick together, they form large, heavier particles called ‘flocs’ which sink to the bottom of the tank. Step 3: Clarification and filtration At this stage, the floc is removed and clarified or settled water is fed through to sand filters to further remove suspended solids. Step 4: Disinfection The final stage of treatment involves disinfection to remove any micro-organisms (germs) left in the water. Chlorine or sodium hypochlorite is added to kill any pathogenic bacteria that might be in the water after filtration. Watercare produces its own sodium hypochlorite on site from electrolysis of common salt. Chlorine evaporates very quickly. For drinking, place the water in a container and let it stand for up to two hours (or put it in the fridge to be used as needed). Finally, fluoride is added to Auckland's treated water supplies at the request of Auckland's legacy councils (prior to Auckland Council integration). Currently, Onehunga and Huia Village are the only Auckland metropolitan areas where fluoride is not added. Lime is also added to help prevent the water supply pipes from corroding. |

| 1424464 | 2016-08-15 04:41:00 | Obviously Hawkes Bay water treatment must be a very low standard. We are likely to see more of this as dairy intensifies. They presumably don't routinely chlorinate water as this report in the UK Guardian says: "The water supply has since been chlorinated but the council were advising residents to continue to boil their water until given the all-clear. " So, they only chlorinate after an infectious outbreak ???????? :badpc: www.theguardian.com |

| 1424465 | 2016-08-15 05:34:00 | And, lets not tell anyone untill its too late. Better sorry than safe I guess . What if someone dies ..... one elderly gent kept drinking heaps of water, to stop dehydration: just making it all worse "Two elderly people were in intensive care, both as a result of the water contamination." "The death of a rest home resident in Havelock North from a gastro-like illness was also being investigated, Radio New Zealand reported." If this was a private company that let employees get poisoned , there would be court cases, huge fines, multiple govt department witch hunts But if its a Council, its all OK. :annoyed: |

| 1424466 | 2016-08-15 06:00:00 | Hastings District Council have the problem. Havelock North is their area. Not Napier. Two separate towns, councils and systems. Get your facts right before you shoot your mouth off!!:punk Ken |

Get your facts right before you shoot your mouth off!!:punk Ken Napier does not chlorinate either. In fact a few places don't, parts of Canterbury, Tasman, etc.... Insane. |

| 1424469 | 2016-08-15 23:22:00 | This DOC study from 1997 on the Heretaunga Plains aquifer makes interesting reading. docs.niwa.co.nz It identifies areas that may be more prone to contamination such as the margins of the plains, but in 1997 pesticides seemed to be of more concern than dairy. |

| 1424470 | 2016-08-18 08:17:00 | So what is the problem with boiling any water before consumption? Tea, Coffee, cooking, a container of boiled water in the bathroom & kitchen. In Africa you have to boil the water which is a bit of a problem if you have no power or fire wood. | mzee (3324) | ||

No foil hats or ear muffs either. ;) |

| 1424472 | 2016-08-18 21:03:00 | In Africa you have to boil the water which is a bit of a problem if you have no power or fire wood. In Africa you don't have water to your tap, and don't pay the council for it. Why should we have to boil water in major centres in a 1st world country? In todays news: -------------------------------------------------------------------------------------------------------------------------- E coli bacteria were found in Christchurch water 14 times during regular tests by Christchurch City Council last year. The figures, released in the wake of the Havelock North water contamination crisis, has prompted calls for the city to reconsider chlorination. Not treating Christchurch drinking water potentially saved "billions of dollars" but one lobbyist said if councillors were personally liable for the consequences they would not take the risk. The council tests water daily for E coli, but it took 24 hours to get results. A total of 5487 samples were tested for E coli over the 2015 to 2016 reporting year. Currently only Akaroa, Takamatua, Duvauchelle and Little River have a chlorinated water supply in Christchurch. Christchurch's water supply is graded "b", or "satisfactory, very low level of risk". Without treating the water with systems such as chlorination, UV light, and membrane filtration, it is impossible for Christchurch to get an "a" rating. John Pfahlert, chief executive of lobby group Water New Zealand, said low risk did not mean no risk. "[In Havelock North] the probability was low, but we've infected 3000 people," he said. "The issue that happened in Havelock North could easily happen in Canterbury. It has happened in Darfield." --------------------------------------------------------------------------------------------------- Yep, friend in Waimakiriri area is another lucky rate payer with no treated water...... I agree with this guy: www.nzherald.co.nz Most shocking, he said, was that the outbreak was preventable with relatively simple treatment. "Whether the bacteria in question are E.coli or campylobacter doesn't really matter. What matters is that the water supply got contaminated by bacteria which could have been treated by chlorine. This is a simple, effective and common treatment for the removal of bacteria and viruses." |
