When considering building a conservatory, garage or any other extension, the local water authority will need to know about what you are planning. Since October 2011, legislation has been in place to ensure that their access to drains is not impeded and that work being completed will not affect their drainage infrastructure.
A build over CCTV survey will help the property owner to comply with the local authority requirements and establish the location, condition, depth and size of all drainage.
Many sewage systems are located near private property, so when extending your home, the build over CCTV survey will establish if the development work will infringe on a public sewer network.
If you are thinking of adding an extension, conservatory or garage to a property, the Drain Doctor build over / pre-build CCTV service will ensure the project proceeds with confidence and that the building work is undertaken in the knowledge that no drain or sewage pipe issues will arise. Our state of the art cameras are used to map out the drainage system and ensure that any new drains implemented meet industry standards.
Property owners and contractors utilise pre-build CCTV drainage for various reasons. Our CCTV drainage equipment helps improve decision making ahead of a build, delivering valuable insight into the location of the entire sewage and drainage infrastructure that might come into play ahead of construction work.
Pre-build surveys from Drain Doctor are used to identify the current drainage system at any property. If considering an extension, our experienced team will take away the stress of any sewage problems and figure out what is required before building work can begin. The CCTV footage will map the drainage layout, identify ownership of the existing drainage and determine the drain depth. We compile all of this critical information and make it available to the architects at the extension planning stage.
The short answer is no. You are not allowed to build a conservatory or extend your home over a drain, manhole or pressurised pumping main as the water authority require access at all times. However, moving the manhole or redirecting the sewer if it is interfering with your plans is an option. In densely populated areas, this is more likely to be a problem and a build over CCTV survey will help establish if it is possible to proceed with a build, and if there is an issue, how to navigate around it.
