Thousands of homes have been left without water after high winds and poor weather battered northern England.
Staff have been working to repair damage to power lines
Two water mains supplying Hexham and the surrounding areas in Northumberland were washed away, leaving up to 10,000 homes without water.
Northumbrian Water is installing a new water main and hopes to have it available by Wednesday. Emergency water tanks have been set up.
About 7,000 people in the North East and Yorkshire are still without power.
Northumbrian Water has set up emergency water tanks in affected areas and is warning all water for drinking and cooking must be boiled.
Cara Hall from Northumbrian Water said: "Because the water mains are actually submerged in the water, we are having to lay brand new water main.
"The repair that we are having to carry out is very difficult, it's awkward. We are having to lay 3km of new water main and as I am sure everyone can appreciate we are working in very difficult weather conditions."
Northumbria Police warned people in the Hexham area to be on their guard against bogus officials claiming to be from the water board.
A spokesman said Northumbrian Water had said its staff would not need access to homes and police warned people to check callers' identification.
John Bird, from Northern Electric Distribution (NEDL) said 10,000 people across the North East and Yorkshire were still without electricity first thing on Monday morning. By 1300 GMT, that had been cut to 7,000.
