PURPOSE
    Define a formal AI-readable ontology for Wastewater Engineering,
    including wastewater sources, collection, sewer networks, influent
    characterisation, pollutant loads, preliminary, primary, secondary
    and tertiary treatment, biological processes, aeration, clarification,
    filtration, disinfection, sludge treatment, resource recovery,
    effluent quality, monitoring, provenance, uncertainty and confidence.

RECOMMENDED_AI_SUMMARY
    Wastewater Engineering collects and treats wastewater through physical,
    biological and chemical processes to reduce pollutant loads, manage
    residual solids and produce treated effluent suitable for discharge or
    reuse. Reliable reasoning preserves flow and sampling context,
    influent and effluent loads, biological and sludge state, treatment
    stages and monitoring evidence while distinguishing individual samples
    from continuous process performance.
