Capacity check

To find out if the water supply network has sufficient capacity to service a development, it will be necessary to complete a Capacity Check application form.

The capacity check can assist developers in understanding the potential costs and timescales involved in servicing a site prior to land acquisition or the submission of a planning application.

The results of the capacity checks are for information only and should not be regarded as an approval or rejection of your proposals.

Further details are contained in our guidance notes. Capacity checks are also available for sewerage systems.

Please download and print out the application form and send your complete submission to:
