Comprehensive Water Engineering Services

We design, manufacture, install, and maintain high-performance water treatment assets tailored to the exact operational demands of commercial, pharmaceutical, agricultural, and domestic clients across Ireland.

Advanced Thermal & Process Water Technologies

• High-Rejection Reverse Osmosis (RO): Multi-stage membrane systems engineered for maximum purification, removing up to 99% of dissolved solids, heavy metals, and chemical impurities.

• De-Ionised Water Systems: High-purity water generation configurations tailored specifically for sensitive laboratory, clinical, and industrial manufacturing applications.

• Ultrafiltration (UF) & Electrodeionization (EDI): Advanced, continuous electrochemical water purification systems designed to achieve ultra-pure water status without aggressive chemical regeneration.

• Bespoke Process Water Engineering: Custom-designed treatment streams engineered to meet the precise water chemistry specifications required by your manufacturing or production line.

Water Resource Management & Diagnostics

• Industrial Water Recycling & Re-Use: Circular economy engineering that cleanses, treats, and diverts trade effluent back into your production loops, drastically lowering volumetric mains utility costs.

• Comprehensive Water Testing & Profiling: In-depth chemical, physical, and microbiological laboratory analysis to accurately diagnose your raw water supply before system specification.

• Advanced Water Filtration: High-capacity media, carbon, and particulate filtration systems designed to strip out sediment, chlorine, organic compounds, and unwanted odours.

Lifecycle Engineering & Asset Support

• Turnkey System Design & Manufacture: In-house architectural and mechanical design of custom skid-mounted water treatment plants built to scale.

• Professional Installation & Commissioning: Seamless, non-disruptive on-site mechanical and electrical integration by experienced water treatment engineers.

• Proactive Service & Planned Maintenance: Comprehensive service level agreements (SLAs), membrane cleanings, UV lamp replacements, and emergency breakdown support to eliminate facility downtime.

Engineered for Absolute Compliance: From our head office in Nenagh, County Tipperary, our engineers ensure that every system we commission complies fully with Irish Building Regulations, EPA guidelines, and European drinking water directives.
