Eighteen research domains, each with three subtopics, linked by explained relationships. The domains are an editorial taxonomy, not performance ratings of any utility. Relationships are original synthesis. Related sources are shown for context and do not prove a relationship.

Directory of domains

The same 18 domains as a list. Works without hover or the graph.

Domain D / Treatment

Recycled water

Treated water can be fit for purpose, and carries nutrients of its own.

Subtopics

  • Treatment class and barriers. Match treatment barriers and exposure risks to intended use.
  • Storage and distribution. Include seasonal mismatch, pipes, tanks and user exposure.
  • Receiving soil and irrigation balance. Assess combined water, salts and nutrient loading for the destination.

  • Dependency

    Polishing and disinfection to Treatment class and barriers: Validated polishing/disinfection barriers govern recycled-water suitability.

    Question raised: Which decisions in C Wastewater treatment or D Recycled water must be settled before the other can be treated as fixed?

    Why connected? (R07)
    Basis: Editorial systems synthesis
    Editorial systems synthesis supplied in the VRCRI relationship register. No source is registered as direct support, and none is registered as qualifying or contrary.
    What remains uncertain
    How strongly one side depends on the other depends on the site, the technology and the regulatory context. No magnitude is asserted.
    Direct supporting evidence
    None registered.
    Qualifying or contradictory evidence
    None registered.
    Contextual references (do not establish this relationship)

    Draft analysis (not reviewed)

    Written to be checked, not relied on. No source supports it yet.

    1. Relationship and direction
    Dependency: Polishing and disinfection (domain C) to Treatment class and barriers (domain D).
    2. Proposed mechanism
    Validated polishing and disinfection steps are what allow treated water to be assigned a recycled-water class. The class depends on documented barriers.
    3. Why it matters
    The class sets permitted uses for recycled water.
    4. What it could change
    Upstream: Process validation. Downstream: Permitted uses and monitoring obligations.
    5. Source support
    None reviewed. 3 unchecked research leads are queued for review; SRC-004 in the register may be relevant context. Leads are not support.
    6. Limits and alternatives
    Class assignment is a regulatory outcome based on validation rules, not on a process description.
    7. What would settle it
    Validation records and regulator approvals for the specific scheme.
  • Constraint

    Receiving soil and irrigation balance to Soil and crop suitability: Irrigation water chemistry must be included in receiving-soil assessment.

    Question raised: Which limits in D Recycled water narrow what K Agricultural use can do?

    Why connected? (R08)
    Basis: Editorial systems synthesis
    Editorial systems synthesis supplied in the VRCRI relationship register. No source is registered as direct support, and none is registered as qualifying or contrary.
    What remains uncertain
    Which limits apply and what their values are depends on jurisdiction and site. No limit values are asserted.
    Direct supporting evidence
    None registered.
    Qualifying or contradictory evidence
    None registered.
    Contextual references (do not establish this relationship)

    Draft analysis (not reviewed)

    Written to be checked, not relied on. No source supports it yet.

    1. Relationship and direction
    Constraint: Receiving soil and irrigation balance (domain D) to Soil and crop suitability (domain K).
    2. Proposed mechanism
    Irrigation water chemistry and the soil's water and salt balance together may affect what soils and crops tolerate over time.
    3. Why it matters
    Suitable use depends on the combined soil and water system, not on the water alone.
    4. What it could change
    Upstream: Irrigation water quality. Downstream: Crop choice, soil management and application rates.
    5. Source support
    None reviewed. 3 unchecked research leads are queued for review. Leads are not support.
    6. Limits and alternatives
    Soil response is site-specific and changes with management.
    7. What would settle it
    Soil survey and irrigation water analysis for the target site.
