If you plan to build on top of or near the pipes, there are some precautions you need to take. The process depends on the ability of the pipes to transport drinking water or wastewater. Construction above (or near) a public (light) or side sewer If the sewer is not domestic and / or with a diameter greater than 160 mm, we only grant permission when we have carried out a CCTV study before construction. You can then perform the authorized work. If the proposals do not complete the self-certification points, a build-over application form can be downloaded from the following link: developerservices-test.southernwater.co.uk/BuildOver/ApplicationForm For sewers over 160 mm in diameter, you must inform us when the work will be 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. If you are building within three metres of a public sewer or one metre of a public side cub view, you will need our permission before starting work. If your answers meet our needs, we will send you an agreement. If this is not the case, we will forward you to request an authorized build-over agreement for which you will have to pay. There is a discount for online payment. I accept that this application does not grant a construction or construction permit for the proposed extension.
Work on site is not expected to begin until the southern water utilities have given written permission. I agree that for the purposes of the Water Industry Act 1991 and the Data Protection Act 1998, the information provided at this request and all accompanying documents may be retained by electronic or other records, such as computer systems, and processed by Southern Water Services and its employees and agents for any purpose related to the company`s legal water and wastewater businesses. Homeowners are responsible for water pipes within their property boundary, which are called feed pipes. Most Build-Overs do not need a CCTV survey, which allows us to get immediate permission. However, if your sewer is not a house or a diameter of more than 160 mm (6 inches), we will order a CCTV study before construction as soon as we agree with your project. If your proposed extension/building is not subject to the building rules or if you are not in a report area, the following instructions will help you complete the application for a declaration of construction….
