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).
In early October 2017 we’ll be changing the direction of water flow within several of our large pipes. This will enable us to empty them ready for the next stage of our cleaning and refurbishment work.
Our team will gradually transfer water along different pipes over a four/five week period to reduce the possibility of disturbing mineral deposits. It is possible that you may experience temporary short term discolouration while this takes place. We understand this can look unpleasant. Further advice to help get your tap water running clear is detailed below.
