KOMEC GLOBAL · Water infrastructure advisory
A selected record of strategy, performance and assurance work in water infrastructure, led by Raef Kobeissi CEng.
Illustrative editorial image · project evidence is anonymised
Professional focus
Strategy, evidence and assurance recur throughout the work. The selected work includes hydraulic modelling, CFD modelling, non-revenue water studies, technical peer reviews and independent water infrastructure advisory.
Where should long-term investment create the greatest resilience?
Selected experience in risk-led trunk-main strategy, investment pathways and the evidence that supports a defensible case.
What is the physical and operational evidence telling us?
Hydraulic modelling, CFD modelling, non-revenue water studies, leakage, pressure and water-asset performance - with the focus on the decision that follows.
Can the proposed approach be relied upon?
Independent engineering judgement, technical peer review and assurance applied to strategies, models, designs and live-system delivery interfaces.
Selected work
These anonymised examples show the technical evidence, personal role and programme-level outcome behind a small selection of assignments.
01Strategy & investment
How should investment protect customers and reduce failure exposure without funding the wrong assets?
Led infrastructure strategy and co-authored the regulatory enhancement case within a wider multidisciplinary programme.
A multi-period investment pathway targeted the highest-risk 600 km of London trunk mains within a 3,600 km network and supported a £150m regulatory trunk-main enhancement case.
02Diagnostics & optimisation
Where should field resources be deployed when leakage evidence and water balances remain uncertain?
Led the analytical framework, combining probabilistic water-balance analysis with condition and operational risk scoring.
The risk-led programme contributed to approximately 12 MLD/year of leakage savings and supported around 120 proactive repairs each year.
03Advanced modelling
Do flow behaviour and residence time justify an operating change, targeted retrofit or capital intervention?
Established and led a specialist CFD service line, from scoping and model development to interpretation and recommendation.
8+ specialist commissions supported water-quality assurance, retrofit evaluation and investment decisions for 4 water utilities.
04Technical assurance
Can new pumping, storage and transmission works be integrated without compromising live-network operation?
Led construction-stage design review and technical assurance across submissions, interfaces and stakeholder coordination.
Independent governance supported construction readiness and resilient integration of 64 MIGD pumping capacity, storage and major mains.

Working approach
The work is structured to make the next decision clearer, not to create analysis for its own sake.
Frame the decision, evidence, constraints and material uncertainty.
Test performance, options, lifecycle value, risk and implementation reality.
Translate the evidence into a clear recommendation and investment pathway.
Protect technical integrity through governance, review and delivery interfaces.
Portfolio evidence
These capabilities recur across the work. They are tools for making an intervention, investment or governance choice clearer - not standalone products.
Network capacity, pressure, resilience, reinforcement and operational options.
Mixing, residence time, water quality and decision-relevant flow behaviour.
Probabilistic water balances, leakage, pressure and intervention priorities.
Independent review of strategies, models, designs and business cases.
Condition, consequence and operational exposure in a single framework.
GIS, SCADA, monitoring and field evidence connected to action.
Leadership context
The portfolio centres on water-system decisions. The wider leadership record provides the scale and context in which those decisions have been made.
Water and infrastructure leadership.
Regulatory trunk-main enhancement case co-authored for London.
Leakage savings supported through risk-led trunk-main analysis.
Potential lifecycle savings identified in confidential water and energy strategy work.
Figures represent selected professional experience. USD 350m+ refers to potential lifecycle savings identified, not realised savings.
Where an independent perspective can help
Not a menu of products: simply the kinds of decision moments where a focused conversation can clarify the evidence, risks and next steps.
When a strategy, business case or asset-priority decision needs a clear challenge on evidence, risk and lifecycle value.
When network, pumping, storage or treatment-asset behaviour needs to be understood before an operating or capital response is chosen.
When a model, design basis, option study or technical proposal needs an independent engineering view before a commitment is made.
When delivery, commissioning and operational resilience must be considered together rather than as separate technical workstreams.
