Residents in Lakeshore can use their water again.
On Wednesday, the municipality had asked people to limit water usage and hold off on doing laundry, dishes and showering so the sanitary system could catch up from all of the recent heavy rain.
Town officials say the system has now fully recovered.
There is rain and the risk of a thunderstorm Thursday night.
A flood warning issued by the Essex Region Conservation Authority is in effect until 12pm on Friday.
