Barrow to Chelvey

Project Outline

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.

Length and project duration

  • SCHEME ONE – 8km, 14 inch Chelvey to Barrow treatment works – completed late 2013.
  • SCHEME TWO – 8km, 21 inch Chelvey to Long Ashton – This work commenced Jan 2014 and will be completed towards the ealy 2015.

Update- 10th April 2014 

Yanley Viaduct Project & Bristol International Balloon Fiesta 

We would like to apologise for any confusion arising from signage that has been put in place on Weston Road, Long Ashton and our most recent scheme update. As stated in the update, we are working closely with North Somerset Council, Highways and Transport department to minimise the interface between our respective traffic management measures. It is planned that traffic management measures required for main sliplining works starting on Weston Road during this month (including 24 hour traffic lights where necessary), will be removed by the end of July 2014 in advance of Bristol International Balloon Fiesta and the Yanley Viaduct Project commencing. The 24 week period includes for any remaining minor works such as removal of bypass pipework, final service pipe connections etc., which may need to be completed outside the main carriageway, without traffic management.

Update as of April 4th

Pipe installed on Scheme 2:  439m

Scheme 2 Update – Chelvey to Long Ashton

Preparatory work in Backwell and Flax Bourton to allow the renovation of the second trunk main between Barrow and Chelvey to commence has now been completed (please see scheme map for details). Renovation work on the 21” main has started with large diameter pipework insertion now underway. Temporary pipework is also being deployed at present near Long Ashton at present to maintain customer supply during the renovation work. The scheme follows a route between our treatment works in Chelvey lane along the A370 to Weston Road/Wildcountry Lane, Long Ashton. Works on this entire scheme are programmed to complete in Spring 2015.

Backwell/Farleigh/Flax Bourton/A370

Renovation work on the 21” Barrow to Chelvey trunk main is now underway between Farliegh and Flax Bourton where slipline insertion of the new 450mm plastic pipe recently started. This work has been progressing well to date and our next works area has now been set up near the junction with Stancombe Lane. Two-way traffic lights have been in use on this section and we apologise for the inconvenience this causes to road users.

In light of North Somerset Council proposals to complete major maintenance works on Yanley viaduct (A370/Long Ashton bypass) later this year, we are working together closely with the Highways and Transport department to minimise the interface between our respective traffic management measures. We are therefore commencing sliplining works on the A370 near Flax Bourton/The Dew Drop Inn and working back towards Backwell. This will help ensure that our remaining traffic management measures on the A370 in late Summer will be separated from the zone affected by those proposed by North Somerset Council.

Long Ashton/Old Weston Road/Old Weston Road/Gatcombe

Work has recently been underway on Weston Road and in the surrounding area to temporarily transfer all customer supplies while the 21” main is taken out of service for renovation. The renovation works on Weston Road are scheduled to commence on the 14th of April and are expected to require 24 weeks for full completion. A new 500mm plastic pipe will be inserted into the existing main for this section of the scheme.

Part of our planned work will see completion of a connection to one of the pipes we renovated in Wildcountry Lane at an earlier stage of our programme. This will require a road closure on Wildcountry Lane while works are carried out in the Junction with Weston Road. The road closure will be in place on Wildcountry Lane from 29th April 2014 for 4 weeks.

Residential traffic, business patrons and emergency services will continue to have access to their properties during the period of the closure; however, other through traffic will not be permitted and diversion routes must be followed.

The entire programme of work on this scheme is set to complete in early 2015. Please continue to expect delays on the A370 in peak traffic hours during our works.

Chelvey Lane

A road closure is currently in place until May 2014.  A major excavation is currently being carried out in Chelvey Lane which has necessitated the full closure of the road to all through traffic for a period. Residents will need to note the position of the current ‘blockade point’ and continue to access from one side of the works area only over the coming weeks.

We apologise for the inconvenience these works cause and assure road users that we are working as quickly as possible to complete this part of the project.

Our teams onsite aim to assist any affected residents or road users wherever possible – should you require assistance as a result of our works, please look out for Land & Marine staff with yellow ‘Here to Help’ stickers on their hard-hats. The work is being carried out by our contracting partner Land & Marine Engineering Limited (L&M).
