The notice affected about 12,000 Rototuna properties, after the positive test for E. coli during routine testing.<\/p>\n
The council said Sunday\u2019s test results showed no E. coli at the Rototuna reservoir or any sites around the city.<\/p>\n
The boil-water notice applied to the Rototuna Water Supply Zone, which covered about 29,000 residents, as well as a small number of Waikato District Council residents supplied from the zone.<\/p>\n
It also applies to the Flagstaff area. <\/p>\n
Only Waikato residents supplied by the Greenhill bulk supply point, being Gordonton and Puketaha, were impacted by the event, the Hamilton City Council said.<\/p>\n
These residents were on the on-demand supply and the rural trickle-feed supply network and must also boil water for as long as the notice was in effect.<\/p>\n
Three Waters director Maire Porter said it was encouraging that the latest water test samples were clear of E. coli.<\/p>\n
She said people should still boil all tapwater and the notice would only lift after three consecutive days of clear tests.<\/p>\n

The water needed boiling before drinking, including making sachet juice or drinks, making ice, food preparation, brushing teeth and preparing infant or toddler formula.<\/p>\n
\u201cWashing hands and good hygiene is important, as E. coli can spread from person to person,\u201d the council said.<\/p>\n
\u201cThis is particularly important around more vulnerable members of the community, like infants, the elderly and people with immuno-compromised conditions.\u201d<\/p>\n
These groups and pregnant people should seek advice about drinking water from their healthcare providers, it said.<\/p>\n
Electric jugs with a cut-off switch could be used as long as they were full, allowing the water to come to the boil and waiting for it to switch off, the notice said.<\/p>\n
\u201cDo not hold the switch down to increase the boiling time.<\/p>\n
\u201cWater can also be placed in a clean metal pan and brought to a rolling boil for one minute. Boiled water should be covered and allowed to cool in the same container.\u201d<\/p>\n
Porter said the council was still investigating the cause of Saturday\u2019s positive test.<\/p>\n
\u201cAn incident management team has been established, and we will be working closely with Taumata Arowai [the Water Services Authority] and the Ministry of Health on next steps.<\/p>\n
Porter said the council\u2019s website and social media channels will carry updates as investigations continue.<\/p>\n
