Coffey’s Process Engineering Team designs, validates, and optimises water and wastewater treatment systems for municipal and industrial clients across Ireland and the UK. Our approach combines first-principles design with piloting and data-driven controls to deliver compliant, operator-friendly plants with low whole-life cost.

Scale and Results
Our portfolio ranges from small wastewater schemes to 81,000 PE works, and from compact water packages to 300 ML/d treatment plants.
A recent industrial project delivered a 2,000 m³/d high-end water treatment system for a dairy and nutrition client, supported by full validation. Outcomes included:
-
Robust compliance from day one
-
Reduced chemical and energy demand
-
Smooth, safe operation
