Barrow to Chelvey
The Chelvey to Barrow renovation scheme is part of a project to renovate 22km of mains in the area. These mains, parts of which were originally laid in the 1860s, supply treated water to the Backwell, Nailsea, Flax Bourton, Barrow Gurney and Long Ashton areas as well as directly into Bristol. The work is needed to improve water quality and ensure the security of water supply for the future. This work will renovate two pipes one at a time.

Technique for Installing
The project will be using a technique called slip lining for the majority of this work. Click on the pdf to find out more about the techniques we use.
Impact on Water Supply
To allow us to carry out the renovation work we will also need to install additional valves at key points on the network. This ‘enabling work’ will allow us to switch between pipes and supplies during the work so that stretches of pipe can be taken out of service for long periods without affecting customer supplies.
This work normally means we have to cut off supply to a defined area for up to 8 hours. All customers affected will be warned 48 hours before the work.
Some road closures will be necessary along parts of the renovation route however, for the majority of the work traffic lights will be used to manage the flow of traffic. A considerable part of the routes will be along the A370. Every effort will be made to ensure we keep disruption down to a minimum, although working in such a busy traffic area will mean some traffic disruption is unavoidable. Traffic lights will be manned at peak times and we will do our best to keep the traffic flowing as smoothly as possible.
The work is being carried out by our contracting partner Land & Marine Engineering Limited (L&M)
