Environmental Information Requests, Welsh Water

Our Reference: EIR/1771/2024



Dear Jessika Venn


Request for Information


We write further to your request for information dated 3^rd April 2024
which we have been considering under
the Environmental Information Regulations 2004.


We can confirm that any conversations we have about tree planting is
through Developer Services department. Details of the proximity of trees
and planting near our networks are set out within the industry guide
‘Design Guide Sewers for Adoption’. As this is an Industry guide, it is
not our document we do not host this on our website.


We do refer to Sustainable Drainage Systems and trees near our assets
within the attached leaflet.


If trees are being added into the street scene from an aesthetic point of
view by the councils, they will include root containment, so they protect
infrastructure like sewers/services and footpath itself. We hold no detail
on the standard design of these.

Turning to enforcement or legal powers, Dŵr Cymru Welsh Water can rely on
the statutory powers set out in the Water Industry Act 1991 (the “Act”)
which provides a wide range of powers and remedies for the protection of
assets/buried infrastructure. Water undertakers require unrestricted
access to repair, maintain or renew assets and therefore can rely on the
provisions of the Act to request or enforce the removal of any matter that
interferes with or obstructs the exercise of such powers.


Matters are generally be dealt with on a case-by-case basis and
consideration should be made for the ecological impact for the removal of
existing trees or planting of new trees.


We hope that this response is clear. Should you have any questions, you
can contact us by email at
[1][email address]


If you are dissatisfied with the handling of your request, you have the
right to ask for an internal review. Internal review requests should be
submitted within 40 working days of the date of receipt of this response
and should be addressed to Company Secretary, Linea, Fortran Road, St
Mellons, Cardiff CF3 0LT.


If you are not content with the outcome of the internal review, you have
the right to apply directly to the Information Commissioner for a


Yours faithfully,
