Newark city workers were going door-to-door with water Tuesday morning after more than 100,000 people were affected by a 72-inch water main break that compromised service in the city as well as nearby Bloomfield and Belleville.

Officials said most of the affected area was experiencing low water pressure but most residents still had water. They estimated the water main break would be repaired by the end of the day.

Kareem Adeem, director of Newark's water and service department, told Gothamist that by late morning, officials had isolated and closed off most of the valves in the area of the break at Branch Brook Park.

Officials in all the affected communities were urging residents to boil water until further notice.
