Explore the connected wastewater-to-regeneration system.

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 A / Upstream

Source control

What enters the sewer determines what ends up in every downstream stream.

Subtopics

  • Catchment inputs. Separate domestic, commercial and industrial sources; record composition and flow over time.
  • Industrial and trade waste. Investigate discharge acceptance and source-control mechanisms before contaminants mix.
  • Source identification and acceptance. Define material provenance, sampling and rejection controls.

Where a decision here travels

Domains reached by following the selected relationship types, by number of steps. Structural reach only; it does not show material flow or size of effect.

Relationships (2)

  • Dependency

    Source identification and acceptance to PFAS and emerging contaminants: Known source and acceptance determine contaminant risk across downstream materials.

    Question raised: Which decisions in A Source control or H Contaminant fate must be settled before the other can be treated as fixed?

    Why connected? (R01)
    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.

    Draft analysis (not reviewed)

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

    1. Relationship and direction
    Dependency: Source identification and acceptance (domain A) to PFAS and emerging contaminants (domain H).
    2. Proposed mechanism
    What a utility knows about who discharges to the sewer, and what it agrees to accept, may set which contaminants can reach the solids and liquids. Inputs that are not screened leave the contaminant profile uncertain.
    3. Why it matters
    It affects how much testing a downstream material may need before any use is considered.
    4. What it could change
    Upstream: Discharger screening and acceptance criteria. Downstream: Testing scope, product qualification and destination options.
    5. Source support
    None reviewed. 3 unchecked research leads are queued for review. Leads are not support.
    6. Limits and alternatives
    Source control does not remove contaminants already in the network or arriving from diffuse household sources, and it does not replace measuring the actual material.
    7. What would settle it
    Catchment discharger records compared with measured PFAS in influent and solids over time.
  • Material flow

    Industrial and trade waste to Primary solids separation: Trade-waste control shapes primary treatment load.

    Question raised: How does a change in A Source control alter the amount or character of what reaches C Wastewater treatment?

    Why connected? (R02)
    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 streams actually move, in what amounts and with what composition, depends on the facility. No quantities 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
    Material flow: Industrial and trade waste (domain A) to Primary solids separation (domain C).
    2. Proposed mechanism
    Trade waste can change the load and character of the flow reaching primary separation, which may change what is captured and the composition of the primary solids.
    3. Why it matters
    Primary solids are the starting material of the solids stream.
    4. What it could change
    Upstream: Trade-waste agreements and pretreatment requirements. Downstream: Quantity and quality of primary solids, and later handling.
    5. Source support
    None reviewed. 3 unchecked research leads are queued for review. Leads are not support.
    6. Limits and alternatives
    The size of any effect depends on the catchment mix. Domestic load may dominate in some catchments.
    7. What would settle it
    Primary solids quantity and composition records alongside trade-waste load records for the same period.
