Work has started to upgrade over 300 metres of water pipes in Chapel-en-le-Frith and Chinley this week.
Water company Severn Trent is replacing ageing water pipes with brand new ones to help reduce the amount of leaks and bursts in the area.
Work has started on Crossings Road in Chapel-en-le-Frith, at the junction with Eccles Road. The team will then move along to the junction of Charley Lane in Chinley, working along this road until they reach the Peak Forest Tramway Trail.
Sections of Crossings Road and Charley Lane will be temporarily closed to through traffic in two phases, to allow work to be completed as quickly and safely as possible.
Road signs and barriers will also be in place for everyone’s safety.
The overall scheme is set to finish before Christmas 2019.
Lisa Orme, from Severn Trent, said: "To ensure residents have a reliable water supply for many years to come and to reduce the number of leaks and bursts in the area, we need to upgrade water pipes along Crossings Road and Charley Lane in the High Peak area.
"To carry out this vital work, which will see ageing pipes being replaced with brand new ones, we’ll need to put temporary road closures in place to keep everyone safe.
"We’d like to thank everyone in advance, for their patience as we work our way through the scheme. When we’re finished, residents in this part of Derbyshire will have a reliable water supply for many years to come."
