A Grey Water facility is necessary for any more buildings so the DDDA are trying to sell the "Canal" idea to us, in order to achieve this facility inexpensively.
In order to pay for it all and have ongoing income they need a large area they "Own" with buildings on it. Hence they propose not just building on the Campshires but out into the Liffey as well.
I take your point that the apparent absence of a fresh water supply differentiates this canal from other canals, but that's only true if the level of the water in the canal is perminantly higher than the high tide level in the Liffey. Do we know that this is intended to be the case, or is that part of what the tender study procedure is supposed to advise on?
I don't remember any special 'grey water' facility in the Kevin Roche / Spencer Dock mega-plan, surely a 'grey water facility' in normal circumstances, is just a big drainage pipe! The 'grey water' is going to end up in the Liffey one way or another, why would they take on all of this extra expense of digging a broad, recreational scale canal? When you say 'inexpensively' cagey, are you factoring in the extra value DDDA accrue from presiding over a bigger development footprint?
I'm not sure if the 'ongoing income' argument stands up. On a map, the amount of actual building footprint looks about the same! What DDDA gain by building on the campshire and out over the Liffey, they lose by digging the canal!
It all adds to the puzzle of the whole thing, as far as I'm concerned, but, with the information available to date, it's like trying to put together a 500 piece puzzle when we've only got six pieces in the box.
Like I said before, I was pretty sure that this was just a kite flying exercise until I saw Dick Gleeson include it in a 'What's in the pipeline for Dublin'
presentation a few weeks back, followed quickly by cagey's post on the tender notice procedure and suddenly it's time to stop cracking jokes about this and get serious about what it means for the future development of Dublin, and what it tell us about the level of vision, or otherwise, of the people in charge of planning in this city.
P.S. [INDENT]Definitely looks like it would be worth trying to get into the Q & A session with the planners on Tuesday (10th June) at 7pm in the Clarion, as posted by lightswitch, or is that just for residents? What was the upshot of the information meeting on the 3rd?[/INDENT]
