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. 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. We advise you to divert pipes around planned buildings or extensions. If you can`t, then channel all the pipes and fittings under the building, so that they can be accessed for repairs. If any of the works are found outside your borders, please see the work near our pipes. 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. For example, if a building was built over our water main and the pipes burst, it would cause considerable damage and compromise the structure of the building, perhaps until the collapse. An undetected long-term leak can damage the foundations of buildings, posing a similar threat to the structure of a building above the leaking pipe. The weight of the building also weighs on the underlying tube, making it much more likely that there will be a burst or leak than would normally be the case. These risks are due to our inability to access the network to perform the necessary maintenance and repair.

Public sewer «Mapped» are those that appear in the public sewer map maintained by your local water and sanitation company, which you can visit and inspect. You can also talk to a real estate search provider, including our Property Searches team, to order an Asset Location Search for your property. There is a tax for making this available. You can ask us for a map showing where our assets are in your country by sending an email to our geographic analysis team – Geographical.AnalysisTeam@affinitywater.co.uk Most Build-Overs do not need a CCTV survey, which allows us to get permission 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. If your answers meet our requirements, we will send you an agreement.
