Richmond Mayor Danny Avula is holding a press conference Friday morning in which he plans to address updates on water service, the city water treatment plant, tests of the water and preparation ahead of the expected winter storm.

A boil-water advisory in Virginia's capital will remain in place at least until Saturday morning, officials said, leaving residents without drinkable tap water for a fourth day following an outage at the city's treatment facility.

Now that pressure has been restored, Hanover and Henrico counties and the City of Richmond all say they expect to remove a boil water notice sometime Saturday.
