Close to 50,000 homes and businesses East of the Reversing Falls Bridge are expected to be under a boil water order until at least Sunday evening.
The order went into affect late last night after high winds and heavy rained stirred up the turbidity or cloudiness of the drinking water.
That can cause sediment or organic matter in the water-shed.
Director of Municipal Operations Paul Groody says he realizes how frustrating this situation is for all of the customers of Saint John Water.
Groody adds close to six million litres of affected water entered the system but points out much needed upgrades to the water system would mean they wouldn't be dealing with this problem.
