The City Water Division has issued a precautionary boil water advisory for portions of its service area due to low water pressure caused by storm-related power outages at the Chain of Rocks Water Treatment Plant.

under the precautionary boil water advisory. The neighborhoods are as follows:

samples before determining when to lift the boil water advisory. Test results will be in 24
