We're constantly working to improve the supply and quality of your water so you continue to receive clean, fresh water for your morning shower and to enjoy a great cuppa.

Some of the pipes which supply water to almost 43,000 properties in the Carlisle area are over 90 years old. Over time natural mineral deposits have built up inside and although these deposits are not harmful, they can sometimes cause the water to become discoloured.

In February 2016 we started a £14 million investment programme to clean and refurbish over 30km of water pipes to improve the quality of water for customers in the Carlisle area. Our work will take around four years to complete and will be split across nine projects.  The overview map indicates where we'll be working (PDF 372KB opens in a new window).

We'll be using a variety of methods which will include:

  • Inserting new plastic pipe into the existing water main (slip lining)
  • Constructing completely new sections of pipe to replace the existing water main (open cut).
  • Using hi-pressure water jetting or pulling sponge swabs through the main to clean it (air scour/swabbing).   




Expected Completion
Project 2 - Fields either side of the M6 at Park Road/Durranhill Road Laying a new section of pipe through the utility corridor underneath the M6 motorway We have working areas in the fields either side of the M6 motorway at junction 43.  Ongoing work in this location.
Project 2 - Fields at Oak Bank (behind Scotby Road) Pipe connection work Ongoing work in this location.
Project 3 - From the junction near the church on the B6263 through to Steele's Bank (Section 2) Road closure details available here (PDF 104KB opens in new window) Road closure expected to be in place from Monday 1 October for approximately 7 weeks.
Project 3 - Between the B6263 from Steele's Bank to Cumwhinton Water Treatment Works. (Section 3) Temporary two-way traffic lights. Click for more information (PDF 201KB opens in new window) Traffic lights in place until Friday 16 November.
Project 3 - Scotby Road between the junctions of Park Road and the Scotby to Wetheral road Scotby road closure and diversion available here (PDF 77KB opens in new window) Road closure in place from Monday 8 October for approximately 4 weeks
Project 3 - London Road and St Cuthbert's Street Temporary traffic management in place while we install a new valve Temporary closure of St Cuthbert's Street between the junctions of London Road and Lindisfarne Street from Monday 29 October for 3 weeks.  Temporary two-way traffic lights will also be required on London Road for the first week of our work.  The traffic lights will be supervised between 7am - 7pm to help keep traffic flowing.


How our work may affect you

We're carrying out this important investment to improve the water network in Carlisle, ensuring customers can receive a reliable and high quality water supply for many years to come

Temporary changes to the appearance of your water supply

During our work there is a possibility that you may experience a slight discolouration to your water supply.  We'll do all we can to prevent this from happening, but we need to take each section of pipe out of operation as our work progresses. 

To ensure we keep taps flowing to homes and businesses, the water will be rerouted and flow direction changed within the pipe network.  This can disturb the sediment, and result in some temporary short term discolouration which we understand can look unpleasant and tends to be more noticeable when filling a glass or running a bath.

Discoloured water is unlikely to be harmful  and can often be cleared by allowing the first incoming cold water tap (usually in the kitchen) to run at a trickle until it clears.  This can clear quickly, but could take longer as it is dependent on how much of the mineral deposit has been disturbed.

Alternatively the water may appear 'cloudy' or 'milky' which is often a result of trapped air while we've been working, this generally disappears as the air escapes from the pipes. If a glass is filled and left to stand for a few minutes, you should notice that tiny air bubbles will rise to the surface and the cloudy appearance will disappear.

Overnight work

For some stages of the project we'll use high pressure water jetting to flush the pipes and remove the mineral deposits from the network.  This work often takes place over night when there is less demand for water. We will be using equipment that will generate noise, however our teams will do all they can to ensure any disruption is kept to an absolute minimum.

Traffic management

We'll be carrying out our work in phases which may require temporary traffic management, lane closures and on occasions we may need to temporarily close roads.

Don't worry, if you live or work in the area, we'll write to customers in advance of the work starting to provide further information about how our work may affect you and provide updates. We'll also hold local community drop-in sessions as the project progresses.

Thank you for bearing with us while we carry out our work. If you have any queries about this work please call us on 0345 672 3723 quoting project number AMEY U.80018815. We'll be happy to help.
