A total of 17 corridors were developed initially, six were then shortlisted: three in the south and three in the north.

At this early stage in the assessment process, the project team has identified that, on balance, one pipeline corridor on each side of the Alton Pumping Station is currently the best fit with the guiding principles.

This is the option that broadly follows the existing pipeline, although there are some places where this is no longer possible.

This is currently our favoured pipeline corridor.

  • In the south (Boorley Green to Alton), our favoured pipeline corridor is Option G.
  • In the north (Alton to the West London Terminal storage facility) our favoured pipeline corridor is Option J.

The interactive map below shows the six corridors that we are now asking for your views on.

How to use the map

This interactive map allows you to see where the existing pipeline is located, the corridor options being consulted on and information about the area, such as environmental information.

You can use the search box to find a specific postcode or an area you’re interested in, such as a town or village. Please include a space in the middle of your postcode.

Adding information

To add the different things to the map, click the three white-lined icon in the top left corner of the map. Select a ‘layer’ title from the drop-down list and it will appear on the interactive map. You can select up to 10 layers at any one time. To de-select a layer, click on the three white-lined icon and select the layer you want to remove.

Please note: data was collected for areas within 10 miles of the pipeline corridor options. Beyond this point, data will not appear.

Identifying features and areas

To identify an area, click on the map and a call out box with a description of that area should appear on the right-hand side of the screen. To remove that screen simply click on the ‘i’ icon.

Changing the view

You can zoom in and out of the interactive map using the plus and minus icons on the right-hand side of the screen.

You can also enter ‘full screen mode’ by clicking on the arrow on the right-hand side of the screen.

Moving around the map

To move around the map, hold down the left-hand button on your mouse and drag the map. You can also use the arrow keys on your keyboard to move the map.

For more information on the corridors, please see Chapter 9 of the Consultation Brochure.

Pipeline installation

Typically, installation of the pipeline itself should take around one to two months in a location; in complex areas, it might take longer. We will need to install the pipeline on private land, but it will not pass under any existing homes.

Once a single pipeline corridor is chosen we will develop our plans for the pipeline route in detail. At the second consultation, we will be able to give more details about the route and the proposed installation in your area.

The installation of the replacement pipeline would follow good industry practice through established techniques.
