As we approach the end of 2020, we’ve been asking Newstalk listeners what the 20 most influential moments of the last 20 years are… We had Brexit, the election of Donald Trump, the Queen in Croke Park, a smoking ban, a whole new way of consuming TV and music - and a pandemic… Over the next few weeks, we’re focusing on one of the Top 20 each day – and today it's the introduction of water charges. Fionnan Sheahan, Ireland Editor with Independent News and Media tells Shane what we learnt from the water charges debacle Michael Brennan, Author of ‘In Deep Water: How People, Politics and Protests Sank Irish Water’  and Paul Murphy, RISE TD for Dublin South West assess the political and social implications from the introduction of water charges. Henry McKean looks back at the public backlash surrounding the creation of Irish Water and tours Stillorgan Reservoir to find out where exactly our water comes from. And Kieran Cuddihy goes deeper into the water charges debacle with Brendan Ogle, National Coordinator of Right2Water and Fergus O’Dowd, Fine Gael TD for Louth & former Minister of State at the Department of the Environment.
