Shannon Water Pipeline - Parteen to Dublin

Water John

Every lifting lock would need a pump anyway, for one.

Pipeline is more efficient. Once it gets to the top of the hill, it just goes downhill on its own by gravity, and does not get contaminated by oil, effluent, etc. The plan is to design the route so this happens, whereas a canal is much harder to control.

Also more under control of IW using a pipe.

Ah that makes sense .
Was stuck in dublin traffic this morning along the canal and was just thinking all that water coming from the Shannon how come they can't use that.
But yeah in a contained pipe line IW have full control of the product.
Thanks.

Fadó, fadó they used to use canal water for the public water supply. The Blessington st bassin was a reservoir fed by the royal canal

Guinness used to use the Grand Canal spur where the luas is now for their water

The other thing to consider about drawing water from the canals is that they didn't just get their water supply from the Shannon. They have to be "fed" along the route by local rivers/water sources. So, if you draw water from the canals in Dublin, it probably wouldn't be coming from the Shannon at all, but from one of those intermediate sources.

Feed Up

Not sure that the Royal and Grand Canals are fed from the Shannon.

In the case of the RC it's fed at the summit level from Lough Owel with additional water piped from Lough Ennell together with additional water sources in both directions. The RC joints the Shannon at Richmond Harbour, Cloondara. Taking gravity into account I can't see the Shannon being a source of water for the RC. I could be wrong though.

Similar would apply to the GC. From what I can recall the summit level is around Robertstown, which is closer to Dublin than Shannon Harbour.

G-Man

7 springs and pollardstown fen is a major source of water to GC, via a special feeder canal. At some stage in 70s/80s attempts were made to drain the fen for agri use. It got stopped and drains were blocked and the fen is a great place to visit.

Guinness I think still use the filter beds at Bluebell, (they look maintained), but for maintenance... Brewing water comes from their own onsite wells, nicely replenished by all those leaking pipes perhaps.

Could the path of the pipeline be maintained as a long distance cycle way. Its not without precedent. The grand canal cycleway from bluebell to lucan only got constructed when ESB needed to use right of way to bury cables from Inchicore to Grange Castle.. It connects some major towns Tullamore, Birr, Nenagh, Limerick. Its likely to be at a reasonable consistent gradient too.

Another problem with the canal is that when it gets to Dublin it's at sea level. In a pipeline it should have pressure in the pipe from the highest point along the pipe 300ft I think it is above sea level, provided there isn't any leaks along the way:rolleyes:.
