Illustrative infrastructure image

Strategic perspective

Direction, investment and confidence in delivery.

Start with the wider water-infrastructure decision: what is needed, which pathway is justified, and what evidence is sufficient to move forward.

01

Water-sector strategy

What should the system be ready for?

Long-term supply resilience, network strategy and asset priorities, informed by demand, operational constraints and uncertainty.

Scenario-led water resource appraisal
02

Investment planning

Where, when and why should investment be made?

Option appraisal, risk-led prioritisation, regulatory enhancement cases and phased investment, balancing performance, cost and deliverability.

Risk-led trunk-main strategy
03

Technical assurance

Is the decision supported by credible evidence?

Independent engineering assurance, technical governance and review of models, designs and delivery interfaces, with assumptions and limitations made explicit.

Live-system assurance experience

Specialist capabilities

The technical depth behind the wider decision.

These disciplines support strategy, investment and assurance—applied individually or together, according to the question.

Case studies

From strategic appraisal to specialist analysis.

Explore 2 studies connecting wider water-infrastructure questions with the technical evidence behind them, with assumptions and limitations stated.

01 · Strategy & investment

Risk-led trunk-main strategy

Decision
How should investment protect customers and reduce failure exposure without funding the wrong assets?
Personal role
Led infrastructure strategy and co-authored the regulatory enhancement case within a wider multidisciplinary programme.
Outcome
A multi-period investment pathway targeted the highest-risk 600 km of trunk mains within a 3,600 km network and supported a multi-million-pound regulatory enhancement case.

02 · Diagnostics & optimisation

Probabilistic leakage and intervention prioritisation

Decision
Where should field resources be deployed when leakage evidence and water balances remain uncertain?
Personal role
Led the analytical framework, combining probabilistic water-balance analysis with condition and operational risk scoring.
Outcome
Risk-led analysis supported leakage reduction and an annual programme of around 120 proactive trunk-main repairs.

03 · Advanced modelling

CFD diagnostics for water quality and asset performance

Decision
Do flow behaviour and residence time justify an operating change, targeted retrofit or capital intervention?
Personal role
Established and led a specialist CFD service line, from scoping and model development to interpretation and recommendation.
Outcome
8+ specialist commissions supported water-quality assurance, retrofit evaluation and investment decisions for 4 water utilities.

04 · Technical assurance

Live-system assurance for a major transmission upgrade

Decision
Can new pumping, storage and transmission works be integrated without compromising live-network operation?
Personal role
Led construction-stage design review and technical assurance across submissions, interfaces and stakeholder coordination.
Outcome
Technical governance supported construction readiness and integration of pumping, storage and major mains within an operating network.

Engineering approach

Start with the question. Build the decision basis.

  1. 01

    Diagnose

    Define the question, constraints and material uncertainty.

  2. 02

    Evaluate

    Compare performance, options, risk and whole-life value.

  3. 03

    Decide

    Translate the findings into an implementable pathway.

  4. 04

    Assure

    Review technical integrity and delivery interfaces.
