Jefferson Parish boil water

Advocate photo by Matthew Hinton -- The East Bank of Jefferson Parish was put under a boil water advisory Thursday morning. 

With water pressure a growing concern across Louisiana, Jefferson Parish has issued a boil water advisory for the East Bank.

Jefferson Parish President Mike Yenni said the advisory was the first for the parish since Hurricane Katrina in 2005. 

The advisory was issued because of the loss of pressure in the distribution system due to the extremely high number of water line breaks caused by the hard freeze, according to a release. The pressure will be restored as soon as possible, but will take at least 2-3 days, the release said.

Similar advisories were issued in the past 24 hours for the East Bank of New Orleans as well as New Orleans East as water pressure dropped below 15 psi. 

Jefferson Parish said Wednesday evening that it would reduce the pressure in its water system by about 20 percent over the day Thursday, a move it said was a precaution due to the continued freezing temperatures.

Yenni's administration said that because of the duration of below-freezing temperatures and their effect on some parish distribution lines and private lines, it would drop pressure from a normal 56 pounds per square inch to 45 psi "to conserve water and better control water consumption."

"Jefferson Parish officials are urging residents to conserve water tonight through tomorrow morning. Please wrap exposed pipes and don’t run your faucets. Please turn off any irrigation systems, underground sprinkler systems, and limit the use of appliances that use water such as dishwashers and washing machines."

Additionally, St. Charles Parish has asked residents to conserve water, and St. John Parish is under a boil water advisory, and has asked residents not to use water if possible.
