Water and wastewater engineering specialist Glanua has opened its first US office in Radnor, Pennsylvania, targeting North America’s booming life sciences and advanced manufacturing sectors. The office, near Philadelphia, marks a major international milestone for the Galway-headquartered contractor, expanding operations beyond Ireland, the UK and continental Europe.

The US business will focus on engineering and designing specialist treatment systems for pharmaceutical, life sciences and food manufacturing facilities, with plans for a North American workforce of over 200 personnel. Chemical engineer Mark McKeever has been appointed US operations director to head the rollout, drawing on Glanua’s European design-build, modular construction and plant-operation experience.

Karl Zimmerer, Group Managing Director, said: “The scale of US investment in pharmaceutical and advanced manufacturing is creating strong demand for specialist water engineering expertise. Our practical experience allows us to develop solutions that reduce delivery and operational risk for clients.”

Supported by Enterprise Ireland, the expansion coincides with recent rapid growth. Glanua’s headcount rose from 545 to over 750 employees, and its 2025 revenue reached €155m, projected to exceed €200m this year. Backed by a €900m order book running to 2030, the firm aims to reach €400m in annual revenue by 2028.

Alongside its US entry, Glanua continues scaling its Irish and UK infrastructure portfolios under Uisce Éireann and AMP8 framework programmes. Meanwhile, its Lisbon engineering hub has expanded to over 20 professionals, supporting broader growth across industrial water reuse and
