A significant upgrade to the Cromwell wastewater treatment plant will be complete by early August but another big project is behind schedule, the Central Otago District Council says.
The Cromwell wastewater project, budgeted at $5.7million, is the council's most significant wastewater project in terms of cost and scale prior to the Clyde wastewater project, work on which is due to begin this year.
The Cromwell plant upgrade would help the council meet more stringent discharge quality conditions.
Council infrastructure services executive manager Julie Muir said on Monday at the council's audit and risk committee meeting the Cromwell wastewater project was now in its final stages.
"The project has gone really well ... and has come in under budget."
Ms Muir anticipated that a formal ceremony would be held site at the end of July or early August.
Another significant water project, the Lake Dunstan water supply, had not progressed in the desired timeframe, Ms Muir said.
"We have to take stock of what we can learn," she said.
One project manager was managing both the Cromwell wastewater and Lake Dunstan projects, she said. This had resulted in delays in investigating the Lake Dunstan project while the Cromwell project needed urgent progress to meet Otago Regional Council resource consent requirements.
