Celtic Anglian Water

What Celtic Anglian Water does

Celtic Anglian Water (CAW) is an Ireland-based water and wastewater infrastructure operator that delivers integrated engineering design, capital works, and operations and maintenance (O&M) services to public water utilities, principally Uisce Éireann and NI Water. Founded in 1998, the company is a wholly-owned subsidiary of Anglian Water Group (UK) operating under Anglian Venture Holdings. CAW manages several of Ireland's largest wastewater treatment assets, including Ringsend WwTW in Dublin (serving 50% of the Republic's population and operated since 1999), Waterford WwTW (since 2010, serving 190,000 people), and Sligo WwTW (since 2009). The company employs approximately 100 professionals and has delivered over EUR100m of capital works at Ringsend while maintaining continuous operational integrity.

CAW's service portfolio spans the full asset lifecycle: engineering design (MEICA, BIM, value engineering, lifecycle assessment), capital works delivery (planning, construction, commissioning), and long-term O&M contracts including process optimisation under LEAN Six Sigma. It deploys advanced treatment technologies including Nereda aerobic granular sludge, Ephyra anaerobic digestion (yielding 20-30% more biogas than conventional AD), CAMBI thermal hydrolysis, combined heat and power (CHP) systems, and ultrafiltration/reverse osmosis/UV water reuse. The company treats over 230 million m³ of water and wastewater annually, generates 65+ million kWh of renewable energy from biogas, and recycles ~20,000 tonnes of biosolids for agricultural use (doubling planned in 2025).

The business model is built on bespoke long-term contracts and framework agreements with government utilities, with revenue generated through managed services fees (O&M) and project-based professional services fees (capital works). CAW pursues new work via Early Contractor Involvement (ECI) frameworks and consortium arrangements, most notably the FaCT3 Consortium (formed 2020 with Farrans Construction and TES Group) which holds Lot 3 Process MEICA status under NI Water's IF106 Framework. The company holds five ISO certifications (9001, 14001, 45001, 50001, 27001) and operates exclusively through direct enterprise sales to public-sector clients, with no consumer or SME exposure.
