Green pumps for a green stadium

Croke Park is a major Gaelic Athletic Association (GAA) sports venue located in Dublin that hosts events for a number of sports. Croke Park has been at the heart of Irish sporting life for over a hundred years, it is not only an iconic landmark but also the third largest stadium in Europe.

Since 1884 the site has been used primarily by the GAA to host Gaelic games, most notably the annual All-Ireland finals in Gaelic Football and Hurling. In honour of Archbishop Thomas Croke, one of the first GAA’s first patrons, the stadium was renamed to Croke Park.

Following a redevelopment programme started in the 1990s, Croke Park currently has a capacity of 82,300, making it the third largest stadium in Europe, and the largest stadium excluding those used for association football. Croke Park has also taken the approach to work towards becoming a “Greener Stadium”: “A part of our mission is working towards a greener stadium on and off the Pitch”, states Tony McGuinness, Events and Safety Manager at Croke Park Management. “Croke Park’s commitment to sustainability is brought to every level within the organisation with all staff playing their part to ensure our goals. Efficient pump operation helps us to reduce our impact on the environment. This is why we rely on Wilo Ireland.”

Wilo Ireland Service Department carries out the maintenance to the various booster sets, pressurisation units and circulating pumps on site. “We’ve now upgraded almost 20 booster systems to high efficiency models, based on energy calculations we’ve done for the customer in advance. This is a part of an overall investment in energy solutions in recent years”, explains Derek Elton, Managing Director Wilo Ireland. “Our Service department has been extensively involved with the replacement, commissioning and maintenance of all high efficiency booster sets in the stadium with some requiring complete disassembly and reassembly in position due to access restrictions.”

The high efficieny variable speed booster set type range Cor-Helixve-VR takes care of all water services requirements, hot and cold as well as the pitch irrigation system. It is essential that the irrigation sprinklers receive the correct water volume at constant pressure to ensure even water distribution on watering the pitch to avoid shading of the pitch surface, which was the criteria for the upgrade. It was also essential that the booster unit responded automatically to the number of sprinklers in operation at any one time, with maximum efficiency both electrically and hydraulically.
