Talk:Thornton Steward Reservoir

Amount of extraction from the Ure
This 2001 document says "Yorkshire Water Services currently abstracts water  from  the River Ure  at Kilgram  Bridge  under  a  time-limited  licence.  The  licence  allows  abstraction  of  46,  22.73,  3.27  tcmd  at  flows  >300,  >163  and  >50  tcmd  respectively,  as  measured  at  the  Kilgram  Bridge  flow  gauging  station. There is zero abstraction at river flows  equal to or <50 tcmd." (where TCMD means "thousand cubic metres per day"). Ideally we'd give an up to date figure - I'm not comfortable using such an old number, particularly after the improvments to the treatment works in 2007. If anyone can find up to date numbers, either of Yorkshire Water's licence limits, or their actual usage, that'd be a useful addition. -- Finlay McWalter··–·Talk 21:10, 8 September 2019 (UTC)

I'm sceptical about the direct Leighton Reservoir connection
The 2007 D&S article cited in the article is pretty clear that Yorkshire Water installed a new pipeline from Leighton Reservoir to Thornton Steward Reservoir. But I'm worried that the journalist misunderstood what they were doing, and in making the article digestible introduced an error, which we're now reproducing. In particular:
 * that's at least 4 miles, as the crow flies - that's a lot of pipeline and it's over hills (or twice as far, if they followed the valleys) - doing all that, with the associated pumping, for just £1 million seems unlikely.
 * why bother? Leighton discharges naturally into the Ure, and Thornton Steward extracts downstream from the Ure - that's only a mile or so of piping
 * the two roads mentioned in the D&S article, Moor Lane and Longdike Lane, are both between the extraction point at Kilgrim Bridge and the south end of Thornton Steward - they're where a pipeline from Kilgrim to Thornton Steward would go, nothing to do with that long trip from Leighton.

So what I think is really the case is that, as the Leighton Reservoir article says, it just keeps the Ure topped up to make up for the extraction, and all the extraction is done (sensibly) at Kilgrim. And the 2007 pipeworks were just the line from Kilgrim to Thornton Steward. So, exactly contrary to what the D&S says, there is not a direct pipeline between the two reservoirs - only the Ure. -- Finlay McWalter··–·Talk 12:40, 9 September 2019 (UTC)
