Drinking water in Shannon and Tokomaru has been assessed as safe to drink meaning long-standing boil water notices have been lifted by Horowhenua District Council.
Horowhenua District Council chief executive David Clapperton says Shannon's new water treatment plant, with its state-of-the-art membrane filtration system, is now fully commissioned, running and producing high quality water.
Tokomaru's boil water notice is, Clapperton said, counter-productive as it gives the perception that the water is contaminated and not potable.
"Boil water notices are required only in situations where the water is contaminated, showing the presence of E-coli which is used as an indicator for bacterial risk.
"These events are referred to as transgressions. In the seven years from 2006 to 2013 there has been only one transgression for contamination in Tokomaru - on 11 February 2011."
Mr Clapperton says the Tokomaru water supply actually produces high quality water, meaning it complies with New Zealand Drinking Water Standards' bacteriological requirements and therefore there is no need to boil the water before use.
If evidence of a transgression was found a temporary boil water notice would be put in place.
Horowhenua Mayor Brendan Duffy said the Council has invested millions of dollars in improving the district's water supplies and continues to do so despite the district's limited rating base.
"There are five drinking water supplies serving Horowhenua. So far, upgrades have been completed for the Shannon and Foxton Beach supplies and are almost complete for the Foxton supply."
Upgrades to the Tokomaru water supply, in order to provide full treatment of the water, are currently scheduled for 2024 to 2025.
The move has the support of the Ministry of Health and MidCentral Health's Public Health Services, who have confirmed the notices are no longer necessary.
