Chlorine is again being added to Napier's water supply following a positive E.coli reading - this time at the Otatara reservoir.
The chlorine free taps located at Tareha Reserve, Guppy Rd, have also been shut as a health precaution.
Chlorine has been added to the city's water supply twice this year after positive E.coli readings.
Today's decision was made following a low level reading for E.coli returned to Napier City Council.
Although the level was at the very lowest limit of detection, a decision was made to commence chlorination of the reservoir, in conjunction with the Hawke's Bay District Health Board and Drinking Water Assessor.
