SAINT JOHN – It will be at least Tuesday or Wednesday before a boil water order is lifted for residents between Russell Street and the Reversing Falls Bridge.

More than 35,000 residents are affected by the order, which was instituted Saturday after a water main dating back 140 years broke on Rothesay Avenue.

Regional Medical Officer of Health Dr. Scott Giffin said this will happen with older pipes.

“It points out the need for further infrastructure analysis and, hopefully, practising some prevention in that getting these older pipes looked after is what will happen,” Giffen said.

Health officials are expecting to receive water test results this afternoon.

Deputy Commissioner of Saint John Water Kendall Mason said the city needs two consecutive negative tests on the water before the order can be lifted, which he said could happen late Tuesday or early Wednesday for most residents.
