The work current planned for Brinsea to Banwell forms part of a new £27 million water main which will secure the supply to 280,000 people across Somerset. 30km of water main will be installed between Barrow Gurney and Cheddar, via Banwell, leaving thousands with a better more reliable water supply. With the population of Somerset predicted to boom over the coming years the main will also cater for the increase in demand.

280,000 people will have a much more secure water supply once the scheme is complete. What this means is Bristol water will be able to get water to the areas such as Cheddar, Banwell, Burnham, Weston-super-Mare and Glastonbury through more than one route. So if there is a burst main leaving you without water Bristol Water can switch to the second main keeping you in water. The population of Somerset and North Somerset is expected to grow by over 100,000 people by 2030, making it one of Europe’s fastest growing areas. This new main will help the area keep in water with this massive increase in demand.

The Latest

Planning permission has now been granted by both North Somerset Council and Sedgemoor District Council. There are certain pre-commencement conditions on the permission relating to newt protection and highways design around the compounds.

It is likely that work will commence in Sedgemoor shortly.

Exactly what is happening between Brinsea to Banwell?

The pipeline will come in from north of Brinsea maily over fields and cutting across Stock Lane and Brinsea Lane, which may need a short duration closure to complete the work. It will then head over fields before cutting across King Road just south of Honeyhall Lane, which is likely to need traffic lights. The Mendip Spring Golf Club will be open at all times.

We then head west mainly cutting across fields but we will need to cross Nye Road and through Thatcher’s Cider Farm.


The schedule for the project is still being worked out. At this stage we cannot say when we will between Brinsea to Banwell. The deadline for the overall project is March 2018.

How did we pick this route? 

The route of the main was narrowed down from eight possible options. The scheme has been designed with the impact on the environment and customers at the forefront as well trying to find the best engineering solutions. There were many obstacles in the way including the airport, many ancient woodlands and of course the Mendip hills which have to be avoided, restricting the possible route options. The final route also minimises the impact on major commuter’s route such as the A38 and A370.

One of the biggest engineering accomplishments of the scheme is the ability to use gravity, rather than pumping, to get water from Barrow all the way to Cheddar. This dramatically reduces the energy usage and means the pumping station in Barrow Gurney does not need to be upgraded. This also keeps the running costs of the main lower once in operation.

The impact on the environment has been at the centre of the design work. The area is rich in biodiversity ranging from Dormice, Great Crested Newts, Bats as well as a range of plant life. Bristol Water aim to leave all sites involved in the project in a better environmental position than at the start. To do this they have designed a Biodiversity Index Score system, which was trialled at a few schemes between 2010 and 2015, included the construction of the Millmarsh Reservoir near Frome. The scheme won a Green Apple Award in 2015 for environmental best practise. Any hedges that need to be felled during the scheme will be kept to 7m gaps as to not disrupt bat navigation routes. The work will also be taking place outside of the bird breeding season to minimise the impact.
