If the existing tube is discovered in a bad condition or the material is the fiber of bad luck, then you must reposition the length of the tube under the structure at your own expense for a construction to be considered. This minimizes the risk of structural plumbing failure after construction and the potential for inconvenience and service losses for you in the future. This provides the location of known water and/or sewer lines, including pipe dimensions and flow direction. Pipe depths and recovery levels are provided when data is available. Don`t worry, just fill in as much of the app as possible with as much detail as possible, even if they are very simple. Your owner or architect should be able to help you. You must create a Build-Over/Near app through our InFlow online portal if you don`t meet our standard criteria. However, many previously private sewers do not appear in our archives. So if you are applying to build above or near a canal, we often need to give you details about nearby sewers and wells. Most Build Overs don`t need a CCTV survey, so we can authorize it immediately. But if your channel is not-in-inland or above 160 mm (6″) In diameter, we order a CCTV survey before construction as soon as we agree with your project.
Under no circumstances do we allow construction by a canal or side sewer, where: Select your own self-lay supplier, NAV or water company To request construction above or near a public sewer, please contact InFlow via the right link. If you are building within three metres of a public canal or one metre from a public side sewer, you will need our permission before starting work. For sewers larger than 160 mm in diameter, you must tell us when construction is complete, so that we can order a ccTV study after construction to check the condition of the sewers. We check CCTV`s surveys before obtaining authorization. NB: If sewers are pumped, construction above or near an agreement will not be permitted and a section 185 “diversion of a public sewer” will be requested.
