What Glanua does
Glanua is a privately held Irish-headquartered engineering group that designs, builds, operates, and maintains critical water, wastewater, and energy infrastructure across Ireland and the United Kingdom. The company was originally established in 1997 and reorganized under the unified Glanua brand in July 2023 (previously BHSL and its Glan Agua, Hydro International, and MEIC subsidiaries). It serves three primary customer segments: municipal water utilities (Uisce Éireann, Thames Water, Yorkshire Water, Northern Ireland Water), industrial manufacturers (notably food and beverage names such as Kerry Group, Glanbia, ABP, Unilever, Coca-Cola, Greencore, and First Milk), and pharmaceutical/life sciences clients. Headquartered in Loughrea, Co. Galway, Glanua operates more than 600 employees across offices in Ireland (Loughrea, Cork, Navan) and the UK (Newton-le-Willows, Bishop's Stortford, Bradford, Shropshire), with an in-house DFMA manufacturing facility in Navan producing galvanized mild steel and stainless steel treatment equipment.
The group's technology portfolio centers on a core suite of water and wastewater treatment systems: Dissolved Air Flotation (DAF), the proprietary Glanua Screw Press for sludge dewatering (claimed up to 80% energy savings versus centrifuge and belt presses, 20% DS typical dewatering, up to 95% solids recovery), Moving Bed Biofilm Reactor (MBBR) biological treatment using high-surface-area carrier media, Step Screens, Aeration Systems, and automated Polymer dosing, complemented by a bespoke engineering capability. Through the Marches Biogas acquisition, it added end-to-end anaerobic digestion and biogas plant design, build, and operation (50kWe to large-scale facilities), and through Aqua Operations it gained a UK industrial O&M platform. The company integrates digital project delivery methodologies, including BIM (recipient of a 2023 Irish Construction Excellence Silver Award), digital twins, 3D modeling, and point cloud scanning into its design-build workflows. It holds a patent for Fluidised Bed Combustion technology and is certified to ISO 9001, 14001, 45001, and 50001.
Glanua's revenue model is a mix of (i) Design & Build EPC contracts, (ii) long-term Operations & Maintenance services covering 60+ facilities with contracts extending to 20 years, (iii) equipment rental, (iv) DFMA/hardware sales from the Navan facility, and (v) authorized service and repair work, including as Ireland's first Grundfos Authorised Service Partner. Pricing is project-specific and quote-based on multi-year contracts, with a direct enterprise field sales motion. The group reported €150M revenue in 2023 (up from €97M in 2022) and has stated a strategic target of €400M by 2028, supported by Rabobank growth funding and an active buy-and-build strategy exemplified by the August 2024 Aqua Operations and January 2025 Marches Biogas acquisitions.
