The Central Otago District Council has urged residents to mind their surroundings as its infrastructure overhaul begins to flow into urban areas of Alexandra.
Work had moved to Alexandra's town centre this week as a kilometre-long wastewater pipeline along Tarbert St and Rivers St was being built.
The development is part of a pipeline which will take waste from Clyde's new reticulated wastewater system to the Alexandra Wastewater Treatment Plant.
Central Otago District Council capital projects programme manager Patrick Keenan said about 90% of the wastewater pipeline had been installed with only the sections at each end of the pipeline still to be completed.
The pipeline is part of a the $13.6million stage 1 of the Clyde Wastewater Project which also includes a pumping station and the new reticulated wastewater system in central Clyde.
Mr Keenan said accessways to some businesses at the top end of Tarbert St would be disrupted and there would be fewer places to park.
''We've talked directly with business owners and residents that will be most affected and we appreciate that this is an inconvenience and disruptive for them.
''We ask that people be patient and consider others.''
Work is expected to finish on December 14.
