  • North Bristol relief sewer

    We’re investing £55 million to build a new relief sewer in North Bristol with construction due to start at the end of summer 2019. The relief sewer is needed to ensure the sewerage network can cope with ongoing and future development in Bristol and South Gloucestershire.

    The North Bristol relief sewer forms an essential part of our long-term sewerage strategy for the next 100 years.

    A 6km pipeline will be built under the M5 motorway and Network Rail's Henbury Loop freight railway. It will link to the new Frome Valley relief sewer we have just built from Frampton Cotterell to Bradley Stoke.

    Once connected, these new sewers will direct sewage around North Bristol to our water recycling centre in Avonmouth.

    How will it affect local residents and businesses?

    Where possible the new pipework will be built deep underground by tunnelling. However, in some places this will not be possible so we will lay the pipe in a trench.

    We will do everything we can to minimise disruption to the local community.

    Construction is expected to start at the end of summer 2019 and will take approximately 2.5 years to complete.

    We will be working with contractors J Murphy & Sons Ltd to construct the tunnel and lay the pipework.
