ITV News Meridian reporter Chlöe Oliver meets those affected by the water shortage
Residents, schools and businesses have been left relying on bottled water across much of South Hampshire because of water supply problems.
Southern Water said that Yew Hill storage reservoir, that supplies much of the SO and PO post code areas, lost water overnight because of the bad weather.
It has not yet been confirmed how long the problems are due to last.
Which post codes have been affected?
Southern Water has confirmed problems in the following areas:
SO16, SO18, SO19, SO21, SO22, SO23, SO30, SO31, SO32, SO50, SO51, SO52, SO53
Chamberlayne College for the Arts in Southampton was among the locations affected by the loss of supply.
It was forced to close because of the supply issues, sending its 600 pupils home only an hour or so after they'd arrived.
"It's really frustrating.
"The children are looking forward to coming back, particularly after a bank holiday weekend."
"We made it into period 2 before realising we can't make it through the day with the water we've got."
Paul Bryne, who runs a hair salon in the city and has been forced to shut, said he had "no water whatsoever."
"I've had to phone clients up, cancel them, move them around, which in these times is really difficult when you're fully booked."
Southern Water say they're doing all they can to fix the problem, which was caused by power outages in Monday's storm.
Simon Parker, from the company, said "emergency contingency plans" had been deployed to make sure people could get access to water.
"There's about 30,000 homes that could be affected but we haven't seen anywhere that number affected so far," he said, adding that "teams are working round the clock" to try and restore supplies on Tuesday.
