Roy Thompson, who lives on Alec Robins Rd, near Lakes Hayes Estate, addressed the committee during a public forum, on behalf of his family and four neighbours. The road runs off State Highway 6 between Lake Hayes Estate and the Arrowtown-Lake Hayes Rd.
Mr Thompson said the group was requesting the committee's help "and perhaps even mercy" ahead of the 2009-10 summer.
He asked for the five homes to be included in the Lake Hayes water scheme.
"We live at Alec Robins Rd and we rely on water drawn from Hayes Creek. It's our only source of water.
"In summer, that's become an increasingly unsatisfactory source of clean water for us.
"Lake Hayes suffers from algal bloom, increasing in the summer months.
"Our water becomes green, smelly and tests have shown it's not fit for drinking."
Mr Thompson said the situation was complicated further because in that location, bore water was not an option.
"Underneath our area there's lime, and the water can't be treated and it's not fit for consumption either.
"We are left with absolutely no options and we're getting desperate for some help."
He told the committee there were three houses on Alec Robins Rd which were already in the scheme. Those homes were in the rural residential zone.
Mr Thompson's home and those of his four neighbours were in the rural general zone.
"We are desperate for help," he said.
The homes would only use the portable supply for water inside the house. Water for irrigation would still be drawn from Hayes Creek.
Council Infrastructure Services general manager Mark Kunath said a report could be prepared to look at options for the five homes.
After the meeting, Mr Thompson told the Queenstown Times he had lived on the property since 2005 and the green water "comes and goes, depending on how the algal bloom is in Lake Hayes".
It was the first time he had officially approached the council asking for help, and he said he was pleased with the outcome.
"It's not a problem with the council's services, it's a problem with the quality of the Lake Hayes water."
A group of Lake Hayes residents, concerned about the quality of the lake water, had been established and was "doing some good work" with the council, Maf and Niwa.
"They're monitoring what's going on in the lake, and they're trying to come up with some creative ways to address the issues," Mr Thompson said.
Part of the problem with the Lake Hayes water supply was, in summer, a "band" of about 1.5m was oxygenated.
"In summer, most of the water in there is . . . dead.
"There is a band that's OK for fish to live in."
