Clean water capacity enquiry

If you are planning a new development our Planning Team can offer advice and guidance to help with your enquiry

The Developer Services Planning Team is changing the way we manage your pre planning enquiries.

With effect from 1 April 2015 you will be able to apply for a desk-top study for both clean potable water and sewerage services. 

We will be introducing a fee for this service for sites which have 10 or more domestic dwellings and/or any commercial or industrial premises.  For more information regarding these charges, please click here.

For clean water capacity enquiries, please complete the Pre development capacity enquiry form.

This can be completed either by using our online application form, or click here to download the form.

Before construction can begin, most types of development or building work will need planning permission from the local planning authority.

Whilst we are not a statutory consultant for planning applications, we endeavour to review all applications for planning permission that are submitted to local authorities. We do this to ensure that any development does not compromise our assets including water and waste water networks, which ultimately protects the service we supply to our customers.

Co-operation between South West Water and developers or agents at an early stage of development planning is important to avoid potential delays at the point of planning application. Through early discussions about the proposed development we can understand, advise and plan how we can support the requirements of a proposed development. You may also find our water and waste water service maps useful.

A capacity check is required to see if the water distribution network has sufficient capacity to service a development. Our Development Planning team will inform you if there is adequate capacity for your development and if there is any existing equipment on site that could affect your plans.

This will not be required for developments of up to five single dwellings that will be connected directly to an existing South West Water main. For larger developments it will be necessary to complete a Pre development capacity enquiry .
