A project to replace water pipes along Klein Constantia Road, between Croft and Pagasvlei roads, Summit Way and Muscat Road, is under way, according to ward councillor Carolynne Franklin.
The contractor, Nejeni Construction and Project Management, has been appointed and the project is at a pre-construction stage of finalising contractual documentation.
Ms Franklin said construction was due to start today, Thursday September 8, and be done by Tuesday January 17.
A water department official said they did not expect any water-supply disruptions for most of the project, only when they connected the newly installed pipeline to the water network, usually at the end of the project.
Council notices would be delivered to affected residents in advance of the water-supply shut-off, and if a larger part of the area was affected, a media release would also be circulated at least three days in advance.
The official said a typical water-supply shut-off for connection of a new pipeline lasted one day, between 8am and 5pm. Multiple shut-off days might be needed if there were more than two connections, but the City staggered the shut-off days to allow residents to replenish their emergency supplies.
