Southern Water Build Over Agreement Fee


This provides the location of known water and/or discharge pipes, including pipe size and flow direction. Pipe depths and coverage levels are reported when data are available. For sewers with a diameter greater than 160 mm, you must inform us once the work is completed, so that we can order a CCTV study after construction to check the condition of the sewers. We will check the CCTV investigative material before granting permission. We advise you to divert the pipes around all the proposed buildings or extensions. If you can`t, channel all pipes and fittings under the building so that they are accessible for repairs. If any of the works are located outside your borders, please see working near our pipes. If the affected sewers require a diversion (relocation, not replacement of existing pipe), you must file a Section 185 application with Southern Water Services: owners are responsible for water pipes that are within their property boundary, which are called supply pipes. If you are building on top of or near a domestic sewer with a diameter of less than or 160 mm and you can prove that your plans pose a low risk to the pipe, we may be able to grant a self-certified construction agreement. If you have requested a full build-over agreement, we will contact you within 21 days of your application. We will discuss your proposal with you, including any details that may need to be changed.
