Enterprise Ireland recently hosted a two-day 'Efficiency Through Innovation' event, which was held in Dublin. A 65-strong delegation of UK water companies, consultants, Tier 1 contractors and Irish SMEs were hosted by Enterprise Ireland at their headquarters under their 'HubH2O' initiative. The event comprised of a half-day conference and a series of site visits to showcase Irish innovation in the water sector and to offer the UK visitors a fresh perspective on efficiency options in the delivery of treatment solutions. The event kicked off with a half-day conference held at the Enterprise Ireland headquarters. Following insightful presentations from Regina Finn (ex-Ofwat CEO), Yorkshire Water and Irish Water, EPS provided an overview of the Nereda® granular activated sludge technology. Michael O'Sullivan outlined the benefits and successes of the operational plants at Clonakilty and Carrigtwohill, and demonstrated how the learning from these installations is being used to drive further efficiencies in the current project at Cork Lower Harbour and the upcoming schemes across the UK. EPS is the Nereda® licensee for Ireland and is also working in partnership with IP holders Royal Haskoning DHV to develop and deliver schemes for Scottish Water, Thames Water, United Utilities and Anglian Water. EPS is also delivering new assets to the UK water sector using BIM-led digital design systems and off-site construction techniques, mostly through its MEPS Joint Venture vehicle. Shaun Stevens, EPS business development manager, used a series of case studies to illustrate to the assembled audience the company's capabilities in this area. Particular focus was given to the substantial project-level benefits that can be earned by adopting key methodologies such as early supplier engagement, cross-functional collaborative planning, federated modelling, 4D rehearsed installation and digital commissioning. The delegation was taken on a guided tour of the wastewater neutralisation plant at the Diageo Guinness brewery in Dublin city centre. The plant is confined to a small corner of this vast industrial site, and was constructed in and around the previous end-of-life treatment system, presenting significant challenges in terms of space and clash detection. Much of the new plant was located on elevated platforms, leaving the old plant to continue functioning beneath and around it, until it could be switched off and removed.
