South shore boil-water advisory still in effect
A boil-water advisory affecting large sections of the south shore will remain in effect until at least noon Friday, according to a city spokesperson.
Jacques Tetrault tells CJAD they have to be sure the water is completely free of bacteria before they can lift it.
This follows a massive water main break on Roland-Therrien Blvd. in Longueuil Wednesday morning. The advisory touches residents of Old Longueuil and St-Hubert, as well as Boucherville, St-bruno de Montarville and Carignan-sur-le-Golf.
It affects about 190,000 residents.
Those residents are being advised to boil their water for at least a minute before consuming it, although the advisory does say hot water can be used for washing dishes and clothes, and for showering or taking baths.
They say it's a preventive measure.
Meanwhile, the city says it now knows what may have caused the break.
Tetrault explains when they dug the pipe they found that workers made a mistake when installing it fifty years ago. He says that instead of using sand to cover the top of the concrete, workers poured gravel.
"There was a friction between the concrete and the gravel that led to minor cracks, and water got in it, which eventually caused corrosion."
