Napier City Council has announced a second positive result for e-coli in the Enfield Road water reservoir.
On Thursday the Hawke's Bay District Health Board and Napier City Council agreed to chlorinate Napier's Enfield Rd reservoir after routine testing returned a positive test for e-coli.
Another positive result was returned today, however the council was reassuring residents it showed the very lowest e-coli reading detectable and the source had been isolated to one tank of the two housed at the reservoir.
Napier City Council's Manager Asset Strategy Chris Dolley said, "the reservoir is made up of two tanks - the largest of the two has returned consistently clear results however the smaller of the two has tested positive for e-coli".
The small tank has now been shut off and will not be used for city water supply until further notice.
