City officials announced Friday morning that residents of Beverly, Morgan Park and Mount Greenwood, no longer have to boil their water after an outage cut power to the Roseland Pumping Station.

The boil order was in place for approximately 20 hours and included homes and businesses between as far west as Albany Avenue, north of 119th Street and west of Interstate 57 to southwest of Beverly Avenue, officials said.

Microbiological samples analyzed by the Department of Water Management’s Water Purification Laboratories verified that the water is safe to drink, according to a statement from city officials.

There will be an investigation to determine the exact cause of the outage at the pumping station, officials said.

City officials initially blamed the outage that lasted from 8:30 to 9:30 a.m. Thursday at the Roseland Pumping Station on scheduled maintenance work by Commonwealth Edison. However, officials with the utility said the work had nothing to do with the outage.

The boil order was announced just after noon Thursday.

The age of the century-old pumping station was not a factor, said Andrea Cheng, deputy commissioner for the Department of Water Management.

City water officials encouraged all residents to flush all faucets, coolers and drinking fountains by running cold water for five minutes.

Automatic icemakers should also be flushed by making and discarding three batches of ice.

Hot water tanks and reservoirs should also be drained and refilled, officials said. Water softeners and filtration systems should be reset, officials said.
