Everyone who uses the Greater Graymouth water supply should boil the water before using it to drink, cook, prepare food or mix the baby’s formula or brush your teeth until the warning is updated – says the Gray District Council.

- The west coast city of Graymouth and the surrounding areas remain under a boiling water warning due to contamination
- Gray District Council is investigating how Greater Graymouth Water Network has been vulnerable to bacteria
- The boiling water warning cannot be raised until three consecutive days of clear tests are completed
Local authorities identified an area of the Greymouth water network that could have been contaminated, with the city and the larger district to remain under a boiling water warning.
Some schools and companies in the city of Costa West have been forced to close due to the warning, although others are causing it to work, as the community is waiting for a relief for the alert next week.
The Gray District Council issued the boiling warning to customers connected to the Greater Graymouth water supply on Wednesday morning.
It came after water samples found coliforms – types of bacteria linked to human and animal waste – in the network, including E. coli.
On Thursday, the advice said the latest tests showed that the total coliform levels were appearing only in the Kaiata water supply zone and decreased significantly.
None E.Coli was evident in Thursday tests, said a gate.
“We are confident that the actions we are taking are helping to reduce these levels.”

Bottled water has become a valuable merchandise in the city, with schools and companies persevering through interruption.
Cobden School moved quickly to supply bottled water on Wednesday for its students.
But the principal Noula Markham explained that doing this for the rest of the week was logistically very difficult, with the closure of school on Thursday and Friday.
“It was not a decision that was made outside the cuff,” said Markham.
“[On Wednesday] We have water in the supermarket, but when water stocks have been exhausted all day … we could not say with confidence that we were able to give drinking water to all our students without getting bottled water. “
“Logistics around boiling water and cooling … Our school has 107 children. Other areas of the country can call it [small]But there are still many children to give water. “
Hundreds of Greymouth High School students were also invited to stay at home with organized on -line learning.
Other schools continued, including Gray Main School, which has a roll of about 200.
Associated director Rochelle Clark said students were invited to bring their own water bottles.
“We have a supply here for students who cannot bring on their own or forgot their own bottle of drink,” said Clark.
“Most students (Thursday) brought their own water from home, cooked water or bought water.”
The school janitor had provided a tank of treated water that was being tested regularly, as a reserve, said Clark.
“If the worst is the worst, we have it if we need it, but we only have [a day] to the left of the term. “
Cafe and Restaurant Sevenpenny also used filtered rainwater, which had come directly from the property of one of the owners.
Other coffee and food salespeople, such as the courtyard, said at a social media station, it would not be negotiated until the authorities gave everything clear.
“After reviewing the extra requirements for our operation that is outside our current risk management plan and, as it is expected to be for a brief period, we will not negotiate until this problem is resolved,” they said.
Alternative solutions were also needed at Greymouth’s Te Nīkau Gray hospital.
Nursing director at Whatu Ora Canterbury and West Coast, Becky Hickmott, said an incident management team was created at the hospital.
“We are doing our best to keep up with supplies to ensure that everything is working without problems.
“The zippered water boiler cannot be used because it does not boil at high enough for safety.
“We have bottled water being delivered in all clinical areas to patients and employees.”
Contents to the hospital were being developed, including a higher supply of water available at the scene, said Hickmott.
