Residents of Harrow and Colchester South are temporarily banned from washing their cars, watering their lawns and gardens and other outdoor uses of water.
The City of Essex also works with a nearby water supply system in case of emergency shortages.
Essex City Council said on Wednesday evening it was declaring a temporary ban on residential customers at the Harrow and Colchester South sewage treatment plant ‘immediately, until further notice’.
The cause, he said, is “extreme weather events on the shores of Lake Erie,” which caused “a significant reduction in water levels.”
People are also using more water in light of the warmer weather, the city said in the advisory. This places “a burden on the system”.
Residents should limit non-essential water use as much as possible to reduce demand on the system, the city said.
The city has also closed the Harrow and Colchester wading pools.
People can check their water bills to see if they are customers of the Harrow and Colchester South sewage treatment plant.
“It is essential that the residents of Harrow and Colchester South suspend the use of outdoor water as a precaution to ensure that we do not experience a serious shortage. Mayor Richard Meloche said in the statement.
Essex is also working with Union Water Supply to get more water in an emergency.
