I already have my first doubting Thomas (see comment on yesterday's post).
So, if you look at Highlands own report, Volume 1 of 4, page 14, it says:
"The actual amount of water that will require management will vary depending on the extraction areas in operation and/or rehabilited. The daily average amount of water to be managed upon completion of the quarry and rehabilitation with the COA and four fully excavated extraction areas, is calculated to be about 599,000 cubic metres a day (converted that is the 600 MILLION litres a day.)"
So lets remember the only way to keep the holes dry is, according to their own studies, to operate 16 pumps 24/7 managing 600 MILLION litres of water a day.
At least there will be lots of local jobs......doing this:
