The City of Kelowna announced the news on Friday, stating the boil water notice was due to low water demand and residual chlorine required for drinking water disinfection.
The city said residents using the South East Kelowna Irrigation District water supply for drinking are asked to use precautions.
Several roads are under the boil water notice, including Balldock Road, Gaspardone Road, Harvard Road, KLO Road and McCulloch Road.
