TfL Ref: FOI-1884-2425
Thank you for your request which we received on 10 September 2024, asking for drainage diagrams and plans of any subsequent modifications to the Tolworth underpass.
Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy.
Unfortunately, we do not hold the information you have requested. We have gully information, but we found no records of the layout of the drainage at the A3 Tolworth underpass. However, drainage details of the underpass could be found in any public sewer information. I recommend that you contact the relevant water company.
I’m sorry not to be able to help you further on this occasion.
Please see the attached information sheet for details of your right to appeal.
Yours sincerely
Eva Hextall
