Planning an Extension? You Will Require Severn Trent Water’s Approval First.

During the early part of 2021, we have been supporting clients in the Birmingham and surrounding areas in preparation for them to start their works on building extensions to their properties.

How?

In the initial stages of planning your extension it is a requirement to have a CCTV Drain Survey completed if you are planning to build over or near to a Severn Trent main sewer line. Further information can be found on Severn Trent main website on their requirements (click here). In summary, you cannot commence building works if there are sewer pipes within your boundary without your water company's approval. You will have to have a prior CCTV drain survey completed on the condition and location of the main sewer line on your property.


Once the survey is completed and you have the report, you can send it to Severn Trent Water to approve either by a Self-Certification Declaration or a Formal Build Over Agreement. Once approved, this is when you get the go ahead to start building your lovely new extensions (subject to any other approvals you made need such as planning permission and/or building regulations).


Our drainage engineers:

  • Are fully equipped with CCTV Camera equipment to meet your drainage needs when it comes to surveying the drainage run(s).

  • Use the correct coding recognised for defects and screenshot if any are significantly detected.

  • Produce inspection reports to WRc standards including details on the sections surveyed such as pipe type (foul or surface water), pipe material, pipe size, pipe depth, condition classification, drain connections, defects and recommendations as well as photographs of significant defects.

  • Will produce a site map of the drainage system in block plan format showing your existing building structure and if possible the newly proposed extension (if available during time of survey).


Our clients have been so happy with our engineer’s assistance during the initial stages in getting their build over or near to surveys completed. Here are a couple of recent kind words from our lovely clients from Google My Business and Checkatrade.

“We needed a survey performing in preparation for building work. The guys were friendly, professional, communicative and timely - if only all tradespeople took this approach.


It’s not just our presence on site conducting the survey or our high quality reports that gets us our valuable reputation, but also our aftercare in helping our clients with questions they may need answers to in regards to the application process for their extensions and assisting with any queries from Severn Trent. Our team will assist you every step of the way to make the process less stressful and to get the results and go ahead for their projects.
