    Speaking of fridges....

    I sometimes think we are frozen in time 😊

    I always say fridge🙂

    It's actually an old Gift Grub sketch.

    This project is likely to end up in the courts if plannig is approved (quite likely). Ireland has been very poor in looking after our waterways and still those involved are paid huge increases in salaries.

    Ireland's historically poor management of its water supplies is precisely why a large-scale solution designed to modern standards and EU environmental regs is required.

    I've yet to hear a coherent argument against it, other than a small-minded hatred of Dublin.



  • Registered Users, Registered Users 2 Posts: 9,146 ✭✭✭saabsaab


    This isn't a solution. Dublin needs to stop growing outwards and divert new industry and people where there is water.

    Nope. You were wrong on your previous anti Dublin thread and still wrong.



  • Registered Users, Registered Users 2 Posts: 8,788 ✭✭✭Former Former Former


    divert new industry and people where there is water.

    Right, but then you still need to extract the same amount of water from the rivers.

    So it really isn't about protecting the environment, it's about not wanting to give anything to Dublin.



  • Registered Users, Registered Users 2 Posts: 1,671 ✭✭✭Busman Paddy Lasty


    Not wanting to give anything to Dublin.

    That is why this thread exists and why the OP was banned from their previous identical thread. Ignoring all the other posts about how this isn't just 'water for Dublin', it will allow development in Drogheda, Navan, Mullingar, Athlone and all the other places mentioned on threads. Carlow, Limerick, Tipp etc

    Calling it “whataboutery” avoids engaging with the actual issue, which is national water resilience. Telling people they “get what they deserve” for living in a floodplain is hardly constructive. People live and work along the Shannon for the same reason people live in coastal towns, cities and river valleys everywhere: history, livelihood and community. That doesn’t remove the State’s responsibility to manage infrastructure properly.

    Dragging clan names and parishes into it and then jumping to phrases like “ethnic cleansing” is completely over the top. Nobody is proposing removing anyone from anywhere. A strategic abstraction of a small fraction of the Shannon’s average flow to support multiple regions is not cultural displacement. It is infrastructure planning in a modern state.

    And this constant framing of it as “Dublin versus the environment” ignores a basic fact: most people in Dublin actually have a relatively small environmental footprint. Urban residents are far more likely to use public transport, walk or cycle. They live in apartments and terraced housing with smaller floor areas that require less heating. They share infrastructure, services and utilities at scale. Per capita energy use, land take and transport emissions are typically lower in dense cities than in dispersed rural settings so stop lecturing people that do less environmental damage than you do.

    What would the country be like if we all dispersed from the urban centres to live like you? Turning rural Ireland in to a monster housing estate that's impossible to police or service with public transport and other services.

    It is also not just “for Dublin”. Kildare, Meath, Wicklow and parts of the Midlands are all tied into the same supply strategy. This is about resilience for households, hospitals, industry and future growth across several regions.

    If the concern is environmental impact, then argue the science. If the concern is flood management, then argue the modelling. But throwing around loaded language and historical grievance does not strengthen the case.

    There are absolutely some people who are 100% against it just because of an anti-Dublin bias but there are also people who think that anyone against it (or even questioning it) do so because of an anti-Dublin bias. These groups are two sides of the same coin IMO

    This is a relatively small number of people, some genuine in their concerns (perhaps environmental), others afraid of change, others f€ck Dublin, more looking for increased compo etc are combining to potentially hold up a project that is required for the greater national good.

    It is a fact that Dublin is a key driver of the national economy and its east coast hinterland is where population growth will continue in the decades ahead. Furthermore certain water-intensive industries will need a guaranteed supply of water.

    Lets build it like most well run countries can do. I can only imagine if they tried to build Ardnacrusha now … no chance

    Ok, if it's not anti-Dublin bias, what are the (legitimate) reasons to be against it?

    And if you accept that the East and Midlands (NB, not just Dublin) needs a reliable water supply, what is the alternative?



  • Registered Users, Registered Users 2, Paid Member Posts: 4,250 ✭✭✭MacDanger


    What's going to happen to the downstream river shannon when there's not enough waterflow to meet the minimum requirements for the river plus the abstraction for the water supply pipeline?

    I don't know what the alternative is but if that's one of the arguments for this project i.e. it's not great but it's the least worst, then the proponents of it should at least be able to make that argument and be honest about it

    As I said earlier on the thread, we see people all over the country who would benefit directly from infrastructure projects (Metro North, Bus Connects, etc.) and yet they still oppose them so it's not surprising when you have people who will see no direct benefit from a project but fear that they may be negatively impacted by the project, some of them are likely to oppose it. Dismssing those genuine fears as "anti-Dublin" bias rather than attempting to address them with data is a weak position IMO

    Then less water gets extracted through the pipeline. The current minimum water flow through the river will not change.



  • Registered Users, Registered Users 2, Paid Member Posts: 4,250 ✭✭✭MacDanger


    Ah come on, do you genuinely believe that?

    There'd be absolute uproar if water restrictions were being applied to the areas served by the pipeline in favour of maintaining river flow.



  • Registered Users, Registered Users 2 Posts: 1,671 ✭✭✭Busman Paddy Lasty


    That is exactly the case now! Disputed by one poster here but the Shannon has a minimum flow set by legislation. If anything that minimum flow could be increased as the drinking water removal is a fraction of the Ardnacrusha flows.



  • Registered Users, Registered Users 2, Paid Member Posts: 4,250 ✭✭✭MacDanger


    Has the reduction of flow to Ardnacrusha ever meant the interruption of electricity supply to a large segment of the population? If not, then the two aren't really comparable



  • Registered Users, Registered Users 2 Posts: 8,788 ✭✭✭Former Former Former


    It's a legal requirement for the flow of the river to be maintained so yes, I do believe it.

    The Shannon pipeline isn't just about increasing the volume of water into the system, it's about reducing the reliance on a single source (the Liffey), but that would work both ways. If the flow from the Shannon is reduced, I presume they would just increase the draw from the reservoirs along the Liffey.



  • Registered Users, Registered Users 2 Posts: 795 ✭✭✭JohnDoe2025


    If there are arguments against it, other than anti-Dublin ones, I have yet so see a single coherent one.

    I am not saying there aren't arguments against it, just that none of the ones to date stack up.

    You mean the same uproar when they introduced water restrictions and hosepipe bans instead of turning off the Liffey?

    Stop with the conspiracy theory nonsense, it's been explained over and over that the river flow and the pipeline together will make next to no difference to the reservoir.



  • Registered Users, Registered Users 2, Paid Member Posts: 4,250 ✭✭✭MacDanger


    It is but you can imagine the clamour to change that legislation when there are water restrictions in large parts of the country - see the recent legislative changes to increase the passenger cap at Dublin airport as an example. Now you can argue about whether the government would ascede to that public pressure but it would be disigenuous to pretend that such pressure wouldn't happen and IMO there'd be only one outcome in that scenario



  • Registered Users, Registered Users 2, Paid Member Posts: 4,250 ✭✭✭MacDanger


    You can dismiss it as conspiracy theory nonsense if you want but that's a weak enough position IMO

    If you have a genuine argument to make here, then you're welcome to make it - provide some data e.g. what the governance is around abstraction from the Liffey, what those rates are compared to this proposal and how that is / has been managed. It's a pretty patronising position to take to just dismiss any concern as being anti-Dublin or a conspiracy theory



  • Registered Users, Registered Users 2 Posts: 15,031 ✭✭✭✭Red Silurian


    It's never been about protecting the environment. The water is required so that the Dublin region can expand and develop further. The poster is only arguing that if those developments moved closer to the Shannon river the pipeline wouldn't be needed. The added benefit is that development would be spread more evenly over the country and not just based in Dublin

    You mean using the pipeline in reverse to supply water to the settlements south of Lough Derg?

    It's a nice idea and in theory possible but in reality the country is too small. Droughts would be more likely to affect the entire country at the same time. A drought causing less water in the Shannon would also cause less water in the Liffey and vice-versa. This pipeline will be useless in a drought situation to either side of the pipeline

    No, what I mean is:

    • when rain is plentiful and the rivers are full, use the Shannon pipeline to its max permitted extent and reduce the demand on the Liffey, thus allowing the reservoirs to fill up and no one will notice a difference on the Shannon.
    • if we hit a dry spell and Shannon levels begin to drop, turn down the intake on the pipeline and use the reservoirs to supply more of the demand.

    I just can't believe that the plan is to keep pumping even if the Shannon is running dry. It's not a rational argument at all.



  • Registered Users, Registered Users 2, Paid Member Posts: 4,250 ✭✭✭MacDanger


    That would make sense - using the Liffey to fill Poulaphuca while the Shannon is providing day-to-day requirements during wet periods and then using Poulaphuca to supply when the Shannon has lower flow - it's not awfully clear that that is the plan though? I'd have absolutely no problem with that approach. There would obviously be the areas not serviced by Poulaphuca to be considered but hard to know what % of the supply that would be

    I presume it's engineering / cost reasons that the Shannon pipeline isn't just filling Poulaphuca?



  • Registered Users, Registered Users 2 Posts: 15,031 ✭✭✭✭Red Silurian


    You'd need a lot of reservoirs (or one very big one) to hold enough water for drought times, not criticising, I actually like the idea of building up vast quantities of reserves in such a way

    I'd also that be surprised if pumping anything less than the regular designed capacity of the pipeline over that distance would be in any way cost effective

    What is the hardness of Shannon water compared to Poulaphuca? Would it affect the current pipes?



  • Registered Users, Registered Users 2 Posts: 9,146 ✭✭✭saabsaab


    Shannon water is generally hard. Poulaphuca is soft.
