Take our online questionnaire and find out if you qualify for a free self-certified build-over agreement. This agreement is free of charge and will be served on you immediately by e-mail. 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. 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. You must apply for an authorized agreement if: if you have a construction agreement for a domestic sewer with a diameter not exceeding 160 mm (6″), you can continue the authorized work. If the sewage disposal channel is not domestic and / or has a diameter greater than 160 mm, we will not grant permission until we have carried out a CCTV study before construction. You can then perform the authorized work. 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. 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 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. 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. We may need to carry out additional studies for sewers with a diameter greater than 375 mm. This may delay authorization. Learn more about the process. 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.

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. If we grant you a self-certified build-over agreement, you can start the work immediately, as long as it is described. Don`t worry, just fill in as many details of the app as possible, even if they are very simple. Your client or architect should be able to help you with this. . . .
