    Drain Mapping

    Drain mapping is an essential part of any proposed building work or planning application. If the drains are within 3 meters of your proposed build, certain information needs to be confirmed for your architect, builder, and developer.

    As part of the planning application, your local water authority will require you to provide the necessary information to confirm if a drainage system is located within 3 meters of your proposed build, and whether they are privately owned or public. If so, drain mapping and charting will need to be carried out to confirm the invert level depths, pipe location and dimensions, and to see how close it is to the foundation. With this information, you will be able to confirm to your architect, builder, or developer whether a build over agreement is required.

    If a build-over agreement is required, you will have to carry out a drainage inspection and supply the Local Water Authority (LWA) with a video to confirm the conditions of the pipework prior to any building work being carried out. Once all the building work has been completed, the LWA will require a second CCTV drain inspection to confirm that the drainage system has been installed correctly and that the LWA assets have not been damaged or breached in any way before they issue a sign-off completion note.

      Drainage mapping is the process of creating a map of the drains in an area. This can be done for a variety of reasons, such as planning a construction project or investigating a drainage issue.

      To create a drain map, our mapping engineers will first identify all the drains in the area. Once all the drains have been identified, our engineers will then deploy state-of-the-art mapping equipment to trace all of the underground assets. Our drain mapping surveys are designed to be as non-intrusive as possible and can be carried out with minimal disruption to your property. We are able to do this because our processes and equipment does not require any digging or excavation which saves you time, money, and hassle.

      Our GNSS receivers also provide highly accurate information and measurements which our engineers will compile into a comprehensive drainage plan. This will give you detailed information about the drainage and utility assets that are underneath your property.

      Once the data is compiled, we’ll send the full drainage report to you.

      There are a few different ways to find the drain plans for your house. One way is to contact your local council. They should have records of all the houses in the area and their drainage systems which you may be able to send a request for.

      Another way to find your drain plans is to look online. There are a number of websites that offer downloadable plans for homes. However, these may not be accurate, so it’s always best to check with your local council first.
