Environmental Information Request

 

Dear Mr Richardson

 

Thank you for your environmental information request, please see your
request and our response broken down below:

 

1.    Your request

 

Could you please provide the information on the following:

 

1) The geographical locations of historical confirmed mains water leaks in
the Surrey area, covering the last couple of years but primarily during
the summer of 2018.

 

2) A breakdown of whether the leak was sewage, mains water or ingress.

 

3) Whether the leak was tracked and traced to the source and the length of
time each report took to be resolved.

 

2.    Thames Water's response

 

We’ve assessed the information you’ve requested, regarding the location
and confirmed mains water leaks, if we were to release this information it
would give an indication of the health and potential weaknesses on our
Trunk mains.

 

This could pose a serious national threat, because the information being
disclosed could have deep and profound effects on our national security /
infrastructure (if it got into the wrong hands) and once this category of
information is disclosed under EIR it makes it available to every member
of the public.

 

Anyone could request this information and it could be used in such a way
as to exploit weaknesses across our infrastructure and cause serious harm
and distress to the general public and surrounding infrastructure around
our assets.

 

For the above reason we won’t be releasing this information, the exception
that applies is as follows:

Regulation 12(5)(a), in particular the section of this exemption that
relates to national security and public safety.

3.    Your right to Object

 

If you are dissatisfied with the handling of your request, you have the
right to raise an objection and request us to carry out an internal
review. 

 

The objection should be raised within 40 days of the EIR response being
issued to you and should be addressed to our EIR email address
[2][email address].

 

Please be aware in circumstances where an objection is raised after the
above mentioned 40 days from issue, then the objection will be treated as
a new request.

 

If you remain dissatisfied with the outcome of the internal review, you
can apply, to the Information Commissioner, who will consider whether
Thames Water has complied with its obligations under the Regulations, and
can require Thames Water to remedy any problems. You can find out more
about how to do this at: [3]www.ico.org.uk.

 

Should you have any questions, please don’t hesitate to contact me.

 

 

Yours sincerely,

Morgan Smart
