Work to replace a faulty Macandrew Bay water main will begin on Monday.
The Dunedin City Council decided to replace the existing water main because it had broken numerous times, causing water restrictions for the community.
The council plans to lay the first section of the new main before Christmas.
Work will start on Portobello Rd opposite Greenacres St, progress through the Macandrew Bay Beach Reserve car park and continue along Portobello Rd to the junction with Marion St.
From December 3 to 14, vehicle access to the beach reserve car park will be restricted although pedestrian access will remain.
The car park will be open to vehicles at weekends if possible.
Traffic control will be in place along Portobello Rd, which could cause minor delays.
DCC engineering project manager Camilla Bennett said the car park and Portobello Rd area would be left untouched between December 20 and February 1 to minimise disruption during the holiday period.
Work on the second section of the water pipe, on Marion St and Hellyer St, would start on January 14, she said.
The council will send letters to those directly affected before work commencing.
If temporary water shutdowns are necessary, affected residents will be notified.
Work is expected to be completed by the end of February.
