Southern Water provides an optional Pre-development enquiry to assist developers in identifying possible constraints that may be associated with servicing a development site. The Pre-development enquiry can assist developers in understanding the impact the development proposals will have on our sewerage networks prior to land acquisition or the submission of a planning application. The results of the Pre-development enquiry are for information only and should not be regarded as an approval or rejection of your proposals, nor should the results be used as a basis for design.

Please also note that Southern Water is currently consulting on the New connections charging as directed by Ofwat. Please read through these documents as they may affect your development site in the future.

Please note these assessments are only of the piped networks upstream of the treatment works/surface water outfalls.

In some cases the Pre-development enquiry cannot be completed due to incomplete or insufficient records. In this instance, we may ask the applicant to provide surveys of drainage in the area. These would be conducted at the applicant’s expense.
Pre-development enquiry
This is a simple check that will identify whether the required capacity is available adjacent to or close to the proposed development. Should capacity not be available, you will be provided with an indication of the nearest point at which capacity is available.

It should be noted that a charge will be made for any repeat enquiries.

Should Lack of Capacity be identified a more detailed Feasibility Study could be considered.

We will endeavour to provide you with a written reply within 15 working days of receipt of a complete application. If we are unable to do this you will be contacted and given the reason why.

Important Note: The results of the Pre-development enquiry does not necessarily provide an identified solution for servicing the proposed development site. The Pre-development enquiry is aimed at simply providing an indication of whether capacity is available.

Please refer to the application form for the fee required. This service is only available for developments which are less than 500 units.

To assess the impact of a development greater than 500 units a higher level of review and analysis may be required. This can be undertaken as a Feasibility Study, which can also be used for any scheme to gain the benefit of such more extensive review and analysis.

Should you wish to take advantage of this service, please complete the Feasibility Study Application Form and submit together with the appropriate fees and drawings.

Important Note: The contents of the report are for direct use only by the applicant and are to be kept private and confidential. They may only be disclosed to third parties with the written approval of Southern Water. Such third parties to have no subsequent implied or other right to disclose the contents and information to any other parties.
