The Citizens Energy water outage map shows the majority of the city's east side, including Christian Park, Irvington, and areas north around the fairgrounds are experiencing low pressure because of the break.

A water main break at an apartment in Boston’s Chinatown neighborhood Sunday afternoon caused substantial flooding. A fire sprinkler pipe burst at 18 Hudson St. around 4:51 p.m. Sunday, according to the Boston Police Department.

Gallons of water poured into the streets in the northeast side neighborhood. Blocks were flooded. Greenfield Signs & Lighting was a businesses right in middle of the flood zone. Steve Overbey, the shop foreman, was working in the building when he noticed water.
