A second water burst - just hours after an initial burst was repaired - left homes and businesses without water for a second day.
Some properties in the PR6 and PR7 areas of Chorley were without water from 5.40am yesterday until the evening, while others had poor water pressure.
United Utilities engineers worked throughout the day to make repairs and tankers were used to pump water into the network.
But just a few hours after the repairs were completed, there was another burst further down the pipe on Bolton Road in Adlington.
Properties in the PR6 area were without water or had poor water pressure again from shortly before midnight.
“We’re really sorry about the water problems over the last two days and we’ve been working round the clock to restore supplies.”United Utilities’ spokesman
Adlington St Paul’s Primary School was closed for a second day because of the problem, but St Joseph’s Primary School and Anderton Primary School were both able to open today.
United Utilities sent a team of engineers to the site to resolve the problem.
A spokesman said: “We’re really sorry about the water problems over the last two days and we’ve been working round the clock to restore supplies.
“It took us longer than usual to locate the burst section of pipe on Tuesday and our team worked through into late evening to repair it. Unfortunately, the pipe then burst again a little further along, around midnight.
“We used water tankers to top up supplies and our engineers have installed two new valves this morning so we can bypass the section being repaired.”
Work to repair the pipe was completed this afternoon and United Utilities said at 2.25pm that water should be starting to flow normally again.
They warned it could take up to two hours for the water pressure to return to normal and the water could be cloudy or discoloured due to the disturbance to the pipes.
