Thames Water Process and Timescales
Divert Abandon Sewer If the location of a public sewer prevents land development or property extension, it may be possible to divert the sewer via an adoption agreement. The Water Industry Act (s.185) specifies that you need to have an interest in the land, or adjacent land, to do this. It also defines in what circumstances the developer can make the diversion, provided a s.104/116 agreement has been signed before work starts.
Process and timescales – non-strategic sewers
Our process steps are outlined below. More detailed information will be provided as you progress. The process is a little different for strategic sewers (see further below), as in these cases we will have to do the work.
1,.You submit your application.
2. We carry out a technical review.
3. Within 14 days of receiving your application, we’ll let you know if we need any more information. Once we have everything, within 28 days we’ll send you our technical decision and what you need to do next.
4. If the work is approved, you’ll need to pay inspection fees and sign the legal agreements that need to be in place before work on the sewer(s) can start.
5. You notify us when the diversion is due to take place.
6. Our field engineer periodically inspects the works and lets you know any corrective actions required.
7. When you’ve finished, you provide as-built drawings and CCTV surveys so taht we can update our records and ensure construction has been carried out satisfactorily. We let you know if any corrective works are needed.
8. Once any remedial work has been completed, we issue a provisional vesting certificate.
9. After a one year maintenance period and our final inspection, we issue a final vesting certificate and adopt (take responsibility for) the sewer(s).
Process and timescales – strategic sewers
Except in certain circumstances where we have agreed that you will make the diversion, we will undertake the work. Our process is described below.
You submit your application.
2. Your application is reviewed to determine if the sewer is strategic in nature.
3. Within 5 days of receiving your application, an engineer contacts you to discuss your application and request further information if necessary.
4. Next, our engineer undertakes a preliminary investigation to identify a diversion proposal. Our engineer then discusses the proposal’s impact on the catchment with our network operations and asset planning departments.
5. If there are no objections, within 5 weeks of the proposal a budget estimate and indicative programme are produced. At this stage, if circumstances allow it, we discuss you doing the work under a s.185 agreement.
