An appeal has been lodged against a water reservoir being constructed on the Sugarloaf hill near Cromwell.
The Central Otago District Council applied to itself to establish a water supply reservoir on the lower slopes of the Sugarloaf's northern end.
Independent commissioner David Collins, of Banks Peninsula, heard the application in May and gave consent, subject to 25 conditions.
Bob Perriam, who lives near the site for the reservoir, was one of four people who opposed the application and he has filed an appeal to the Environment Court against the decision.
Environment Court case manager, Chris Jordan, said yesterday the closing date for any submitters to join in support of the appeal was August 11.
After that date, the next stage would be to see if the parties would agree to mediation.
"It's too early yet to say when a hearing might be held or if one is even required," he said.
Mr Perriam had objected to the proposal on the basis that he did not think a new reservoir was needed.
The structure would marr an "iconic landscape", he said.
The council's utilities services manager Peter Greenwood said the reservoir was needed to cater for the growth of the area and to have security of supply for a system that served 250 households.
Under the council's recent changes to its district plan, the Sugarloaf is designated as a significant landscape feature.
