The data has been assessed by a team that has a large amount of experience in various aspects of the water industry whose skills include civil engineering, process engineering, asset management and quantity surveying. Together we believe we have the ability to understand all technical aspects of Bristol Water’s Business Plan, Statement of Case and the large volume of supporting information provided. Trevor Perry Associate Director [email protected] This Report has been amended following the receipt of two responses from Bristol Water; a letter from Greenberg Traurig Maher LLP (GTM) dated 18 June 2015 and a more comprehensive list of “the major errors of fact and understanding” dated 22 June 2015. We do not believe that either of these documents provided any references to any substantial issues. Where this report has been challenged we have changed the text to ensure that our opinion is taken in the context it was intended to be, provided additional evidence in an appropriate footnote and made some additions to ensure the reader fully understands our opinion. We have considered the challenges made to the Initial Findings Report and note that they have not changed our opinion or the conclusions we have reached. We have corrected one error on page 25, paragraph 95. We apologise for this error. Amendments to the report regarding the issues raised by BW have been highlighted in blue font for ease of location, generally other amendments have been annotated with a footnote. Paragraphs have been numbered for ease of reference.
