Every value is quoted from the document and page cited; the quote was checked against that page's text. "Derived" means the reader worked it out from stated figures (shown in the quote). Planning and licence figures are design or permitted values, not measured use; values derived from an EPA annual environmental report (AER), mostly water, are reported use for that year. The note under each quote gives the scope and whether a demand figure is a maximum or an average.
