Operations and Maintenance Services
Trusted by leading water utility companies across the island of Ireland, CAW’s expertise in managing water and wastewater operations is built on a foundation of process optimisation, delivering operational resilience, compliance, sustainability, and efficiency to our clients.
We ensure the sustainable operation of your plant to comply with EU and local regulations, by employing LEAN Six Sigma processes to address potential challenges proactively.
Across the sites we manage we treat over 230 million m3 of water and wastewater per year, and produce enough biogas to provide gas power to the equivalent of over 6500 homes for a year. Plus, at our largest plant, in Dublin, 50% of potable water demand on-site comes from recycled treated effluent.
Our strength lies in working collaboratively with each client to achieve their goals. With over 25 years of experience managing a number of Ireland’s major treatment plants, we consistently deliver exceptional service by combining our extensive expertise with a deep understanding of each client’s unique operational context and KPIs, ensuring their short- and long-term objectives are met.
