Planning liaison

If you have not yet submitted a planning application, we encourage early engagement and discussion with us so that we can assess your proposals.

This will help you to understand how we can provide water and/or sewerage services to your development and work with you to ensure our networks are protected.

At this stage you need to establish your preferred point(s) of connection to our network. We will complete a desktop review and comment on network capacity.

When planning permission is granted, if we have identified a lack of capacity in our water and/or sewer networks we will review in greater detail.

Where capacity improvements are required, we will work with you to seek timely implementation.

Further guidance can be found here [link to capacity]

If we haven't already commented on your planning application, please contact us with the reference number and we will assess and comment on your proposal and consider how your development may affect our network(s) in more detail.

Where necessary, network modelling will be undertaken upon grant of planning permission. This will establish if network capacity improvement(s) is/are required.

If your application is at the reserved matters stage we will expect to see a finalised drainage strategy including the point of connection(s) to our network.

We also expect to see on the site layout how our existing assets are protected and how relevant easements have been observed. See Protection and diversions.

You can apply online if we have not commented on your development previously or contact us with any subsequent queries

At this stage, points of connection (supply, foul and surface water) should be finalised and agreed with us. You should also be aware of any capacity improvements necessary to support your development and have been provided with an indication by Wessex Water of when these will be implemented.

Finalise how your site will be connected to our network [Link to NAV, S41, options] / [Link to sewer connection options]

If planning approval is not required for your development, you may still need to discuss your proposed water and drainage arrangements with us to ensure there is adequate capacity and to avoid any unexpected issues relating to our networks or operational sites.

If you require an increased volume of water to be supplied to your development or need to discharge a larger amount of sewage to our network, we need to know your requirements and proposed flow rates.
