If you're planning any type of development, building something new or extending an existing building, you should check there’s nothing underground that could be affected ie water or wastewater pipes. Our property searches team can supply maps which show the location of our assets.
If you want to build over, or close to, one of our public sewers or lateral drains (this usually means within 3 metres), you need our approval, even if it is located on your land. We have to make sure that all of our pipes are protected from any potential damage that development may cause, so that they can continue to provide the service they're designed for. It's also really important that we can access our pipes for maintenance and repair.
If you need any more information, our Building Over a Public Sewer guide (PDF 585 KB opens in a new window) will give you all help you need to complete the enquiry form.
