Specialist water expertise from a WQA Certified Water Specialist
This is where Same Water goes beyond standard compliance. Our consultancy division handles the complex, specialist work that most water hygiene companies simply can't: designing water systems for new-build and refurbishment projects, investigating and resolving persistent contamination issues, and providing independent expert opinions for disputes and legal proceedings.
Led by Darragh Durkan — a WQA Certified Water Specialist — our consultancy work is grounded in deep technical knowledge, real-world experience, and an unwavering commitment to getting things right. If you need advice that goes beyond a standard risk assessment, this is where we can help.
Water System Design & Specification
Getting the water system right at the design stage is always cheaper, safer, and more effective than retrofitting solutions later. We work with architects, M&E consultants, developers, and building owners to design hot and cold water systems that are compliant, efficient, and practical from day one.
Our design work covers new-build developments, major refurbishments, system upgrades, and extensions. We design to BS EN 806, HTM 04-01 (for healthcare), and current HSE L8 guidance — ensuring that compliance is built into the system, not bolted on afterwards.
What's Included
System Sizing and Specification
Calculating flow rates, pipe sizes, storage volumes, and pump duties to ensure adequate performance.
Pipe Routing and Layout
Designing layouts that minimise dead legs, stagnation risks, and excessive run lengths.
Compliance Review
Reviewing third-party designs for L8 and water hygiene compliance before construction starts.
Healthcare-Specific Design
Designing water systems for hospitals, clinics, and care homes to HTM 04-01 standards, including augmented care requirements.
TMV and Temperature Control Strategy
Selecting and positioning thermostatic mixing valves, specifying thermal control measures, and designing safe hot water distribution.
Diagnostics & Troubleshooting
When Legionella counts won't come down, when a system keeps failing despite repeated cleaning, or when nobody can explain why a building has persistent water quality problems — that's when you need a diagnostics specialist, not another standard risk assessment.
Our diagnostic work is forensic and methodical. We don't guess. We investigate root causes by examining system design, operational practices, water chemistry, biofilm presence, and control measure effectiveness. Then we give you a clear answer and a practical plan to fix it.
Common Scenarios
Independent Expert Witness
When water system issues become disputes — whether that's between landlords and tenants, managing agents and contractors, developers and buyers, or insurers and policyholders — you need an independent expert who can provide an impartial, evidence-based opinion.
Darragh Durkan provides independent expert witness services for civil and regulatory proceedings involving water systems, Legionella, and water hygiene compliance. His opinions are grounded in the WQA Certified Water Specialist credential, over 13 years of industry experience, and a reputation for thoroughness and impartiality.
