PURPOSE
    Define a formal AI-readable ontology for Water Engineering, including
    water sources, abstraction, raw-water quality, water treatment,
    storage, pumping, transmission, distribution, pressure, flow,
    hydraulic networks, demand, leakage, water quality, disinfection,
    monitoring, resilience, resource management, infrastructure,
    provenance, uncertainty, confidence and recursive water-engineering
    reasoning.

CORE_DEFINITION
    Water Engineering is the engineering discipline concerned with the
    sourcing, abstraction, treatment, storage, conveyance, distribution,
    monitoring and sustainable management of water to satisfy defined
    quantity, quality, pressure, reliability and environmental requirements.

    Critical Distinction
        Water-engineering reasoning must distinguish flow rate from demand,
        pressure from hydraulic head, pollutant removal from destruction
        and disinfectant dose from residual. Source, treatment, storage,
        network, node elevation, sampling context and model-versus-field
        provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Water Engineering integrates water resources, treatment, storage,
    pumping and hydraulic distribution to provide water at required
    quantity, quality and pressure. Reliable reasoning preserves source,
    treatment and network identity, node elevations, demand and hydraulic
    state, water-quality sampling context and field evidence while
    distinguishing modelled network behaviour from measured operating
