From today, residents on the Winchmore water supply will have their say on the future of the scheme through a binding referendum.
The referendum is part of the process required to close a small community water scheme.
The proposal to close the scheme was initiated by a request from residents served by the scheme.
Council Assets Manager Andrew Guthrie says eligible residents on the Electoral Roll for the referendum will be mailed voting documents on Wednesday 23 July.
"Information on the proposed closure, including a summary of the Medical Officer of Health's recommendations, will be included with the voting papers," he said.
"If 75 percent or more of votes cast are in favour of the closure, the Winchmore water supply will cease to operate from noon, 14 November this year," said Mr Guthrie.
Voters should return their documents by noon on Thursday 14 August to ensure their views on the Winchmore water supply closure are considered.
A polling booth will be open during normal office hours from Wednesday 23 July until Thursday 14 August at Council Office, 5 Baring Square West, Ashburton.
The results of the referendum will be announced on 20 August.
