DECISION INTERPRETATION No source is used beyond its scope. Codex is international guidance, not a permit. EPA WRAP is a policy/action program, not plant authorization. EU BAT ranges are technical performance comparators, not universal legal limits. 21 CFR and EU hygiene rules control only within their jurisdictions and exact applicability. CONTROL ACTION Add jurisdiction, end use and evidence class to every reuse claim. REQUIRED RECORDS Source; locator; jurisdiction; end-use category; evidence class; date verified; claim IDs. AUDIT / ESCALATION TRIGGER Escalate when a pilot, BAT range or Codex recommendation is presented as legal permission. FOOD2-002 | Sources: B01, B05, B07, B08, B09, B10 | Claim: claim_foodbev002_p02_core KEY Water-reuse evidence must distinguish international guidance, binding food law, competent-authority requirements, BAT comparators and site-specific validation. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: The defensible sequence is source; hazards; end use; applicable legal or authority requirements; treatment barriers; validation; monitoring; verification; and controlled release or diversion.

Microbial, chemical and physical hazards require different controls. A stream that is suitable for cooling-tower makeup may be unsuitable for a food-contact rinse; a potable-quality target may be required in one jurisdiction or end use and unnecessary in another. DECISION INTERPRETATION Executives should approve reuse pathways, not generic "recycled water." Each approved pathway needs a defined source, treatment train, release criteria, diversion response and regulatory basis. The same treatment system can support multiple uses only if each use is independently justified. CONTROL ACTION Create an approved source-to-end-use matrix with release limits and diversion actions. REQUIRED RECORDS Source ID; use ID; hazards; legal requirement; treatment barriers; validation result; monitoring parameters; release criteria. AUDIT / ESCALATION TRIGGER Escalate any pathway with an undefined end use, undefined legal basis or no automatic response to out-of-spec water. FOOD2-003 | Sources: B01, B04, B08, B09 | Claim: claim_foodbev002_p03_core KEY The defensible sequence is source; hazards; end use; applicable legal or authority requirements; treatment barriers; validation; monitoring; verification; and controlled release or diversion. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Water carries function, heat, chemistry and contamination; it should be specified and accounted for like any other process material.

Each role has different quality needs and introduces different contaminants. Treating all water as one utility hides both unnecessary potable-water use and high-risk reuse pathways. DECISION INTERPRETATION Assign a quality specification to each water function and measure both quantity and quality at the point where the function occurs. Water conservation is strongest when the required quality is no higher than necessary but never lower than safety and product requirements. CONTROL ACTION Define a water specification for every major use point. REQUIRED RECORDS Use point; required quality; flow; temperature; pressure; contact class; critical contaminants; owner. AUDIT / ESCALATION TRIGGER Escalate potable water used in high-volume non-contact applications without a documented reason or reclaimed water used in contact applications without validation. FOOD2-004 | Sources: B01, B06, B08, B09 | Claim: claim_foodbev002_p04_core KEY Water carries function, heat, chemistry and contamination; it should be specified and accounted for like any other process material. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: A controlled water-reuse program requires a reconciled balance of intake, internal transfers, product incorporation, evaporation, discharge, recovery and material losses.

Metering only the site inlet and final discharge cannot identify reuse opportunities. DECISION INTERPRETATION Build the balance hierarchically: site -> process area -> major use -> candidate reuse source. Use a consistent reporting period and reconcile unexplained variance before using intensity metrics for investment decisions. CONTROL ACTION Install or validate meters at the major water users and candidate reuse sources. REQUIRED RECORDS Opening/closing tank levels; intake meters; process meters; wastewater flow; production denominator; evaporation estimates; meter uncertainty. AUDIT / ESCALATION TRIGGER Escalate when unexplained water-balance variance is large enough to change the ranking of reuse opportunities. FOOD2-005 | Sources: B01, B06, B10 | Claim: claim_foodbev002_p05_core Facility-specific metering controls the balance; BAT ranges are comparison evidence only. KEY A controlled water-reuse program requires a reconciled balance of intake, internal transfers, product incorporation, evaporation, discharge, recovery and material losses.
Key: Reuse opportunities are identified by matching a defined source to a compatible end use before streams are mixed.

End-use mapping records contact class, product proximity, aerosol potential, worker/public exposure, equipment/material compatibility and required quality. The intersection defines the treatment and validation burden. DECISION INTERPRETATION Prioritize short, stable loops where source quality is high and the end-use requirement is lower than or similar to the source quality. Avoid building complex treatment around a mixed wastewater stream when a cleaner source can be segregated upstream. CONTROL ACTION Create a source-end-use Sankey or matrix and rank candidate loops by risk and treatment gap. REQUIRED RECORDS Source flow; contaminant profile; variability; end-use demand; required quality; temporal match; storage need. AUDIT / ESCALATION TRIGGER Escalate when a reuse project depends on averaging incompatible streams that could have been segregated. FOOD2-006 | Sources: B01, B06 | Claim: claim_foodbev002_p06_core KEY Reuse opportunities are identified by matching a defined source to a compatible end use before streams are mixed. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Fit-for-purpose means the water quality is adequate for the intended use after considering all relevant hazards and exposure pathways.

This is not permission to lower standards arbitrarily. Food safety, product quality and competent-authority requirements define the minimum acceptable quality, and some uses may require potable-quality water or equivalent controls. DECISION INTERPRETATION Create quality classes tied to use categories: ingredient/direct product contact, food-contact surface/final rinse, indirect process contact, closed-loop utility and non-contact utility. Each class should state microbiological, chemical, physical and operational criteria. CONTROL ACTION Publish an internal water-quality-class standard with approved end uses. REQUIRED RECORDS Microbial criteria; chemical panel; turbidity/solids; conductivity; residual disinfectant; temperature; contact class. AUDIT / ESCALATION TRIGGER Escalate any quality class defined only by one indicator such as conductivity or turbidity. FOOD2-007 | Sources: B01, B04, B08, B09 | Claim: claim_foodbev002_p07_core KEY Fit-for-purpose means the water quality is adequate for the intended use after considering all relevant hazards and exposure pathways. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Water category labels are useful only when they correspond to a defined quality and permitted use.

EU hygiene law requires adequate potable water and separation of non-potable systems and places conditions on recycled processing/ingredient water. Codex provides a fit-for-purpose framework that must be applied inside those legal boundaries. DECISION INTERPRETATION Do not assume "reclaimed" means non-potable, "process" means food contact or "utility" means low risk. Define each category by measurable quality, contact route and legal basis. Piping identification and physical separation should follow those definitions. CONTROL ACTION Create controlled definitions and color/label standards for all water systems. REQUIRED RECORDS Water class; specification; legal basis; piping ID; approved uses; prohibited uses; responsible owner. AUDIT / ESCALATION TRIGGER Escalate unlabeled cross-connected systems or categories whose name is used as a substitute for a quality specification. FOOD2-008 | Sources: B01, B08, B09 | Claim: claim_foodbev002_p08_core KEY Water category labels are useful only when they correspond to a defined quality and permitted use. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Microbiological control does not establish chemical safety, and chemical compliance does not establish microbiological control.
CEPA Technical Intelligence Brief | Food, Beverage, Brewing, Distilling & Dairy Edition | @CEPAIntel | @CEPAFoodIntel Page 09 Prepared by EterSolis Waste & Carbon Management | etersolis.com CEPA-TIB-FOODBEV-002-20260906 CEPA TECHNICAL INTELLIGENCE BRIEF | RISK SYSTEM Microbial, chemical and physical hazard framework FOOD2-009 TECHNICAL BASIS Microbial hazards may include pathogens and indicator organisms; chemical hazards can arise from source water, process ingredients, cleaning/sanitation chemistry, corrosion, treatment chemicals, persistent compounds and by-products; physical hazards include particles, turbidity and foreign material. WHO/FAO notes that chemical-water guidance is less mature than microbial guidance and recommends risk-based prioritization. DECISION INTERPRETATION Build separate hazard inventories, then identify common controls and interactions. For example, stronger disinfection may improve microbial control while generating chemical by-products or changing corrosion. Reuse design must manage the combined risk without assuming one surrogate captures all hazards. CONTROL ACTION Require microbial, chemical and physical hazard sign-off for every contact-class reuse loop. REQUIRED RECORDS Source contaminants; process chemicals; corrosion materials; pathogen indicators; treatment chemicals; by-product panel; physical parameters. AUDIT / ESCALATION TRIGGER Escalate reuse approved from microbiological validation alone when plausible chemical hazards remain unassessed. FOOD2-009 | Sources: B01, B04, B11 | Claim: claim_foodbev002_p09_core KEY Microbiological control does not establish chemical safety, and chemical compliance does not establish microbiological control. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Upstream segregation can prevent relatively clean streams from inheriting the treatment burden of high-load or chemically incompatible streams.

Once mixed, the entire flow may inherit the highest treatment burden. DECISION INTERPRETATION Use conductivity, COD/TOC, turbidity, temperature, pH and process-event signals to define diversion logic. Segregation should be based on demonstrated quality patterns, not visual appearance alone. CONTROL ACTION Install source diversion or dedicated collection where stable quality classes exist. REQUIRED RECORDS Flow and quality profile by event; valve logic; diversion destination; tank capacity; contamination upset history. AUDIT / ESCALATION TRIGGER Escalate when a high-value low-load stream is routinely sent to mixed wastewater without a documented reason. FOOD2-010 | Sources: B01, B06, B10 | Claim: claim_foodbev002_p10_core KEY Upstream segregation can prevent relatively clean streams from inheriting the treatment burden of high-load or chemically incompatible streams. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Ingredient and direct product-contact reuse are high-consequence applications and require the strictest applicable legal, food-safety and validation controls.
CEPA Technical Intelligence Brief | Food, Beverage, Brewing, Distilling & Dairy Edition | @CEPAIntel | @CEPAFoodIntel Page 11 Prepared by EterSolis Waste & Carbon Management | etersolis.com CEPA-TIB-FOODBEV-002-20260906 CEPA TECHNICAL INTELLIGENCE BRIEF | HIGH-CONSEQUENCE USE Ingredient and direct product-contact water FOOD2-011 TECHNICAL BASIS Codex general principles and national law require particular caution where water becomes part of food or directly contacts product. U.S. CGMP requires water contacting food to be safe and of adequate sanitary quality. EU rules contain specific conditions for recycled water used in processing or as an ingredient and require that it not present contamination risk. DECISION INTERPRETATION For generic CEPA guidance, do not authorize a direct-contact reuse application. Instead, define the evidence package required: legal basis, source characterization, validated treatment barriers, microbial and chemical verification, product-quality assessment, monitoring, fail-safe diversion and competent-authority acceptance where required. CONTROL ACTION Require executive and food-safety approval for any ingredient/direct-contact reuse pathway. REQUIRED RECORDS Legal interpretation; source hazard profile; validation study; product testing; monitoring limits; diversion test; regulator/authority documentation where applicable. AUDIT / ESCALATION TRIGGER Escalate any direct-contact pathway justified only by treatment technology capability or potable-like analytical results without legal review. FOOD2-011 | Sources: B01, B08, B09 | Claim: claim_foodbev002_p11_core Authorization is jurisdiction- and use-specific; this publication does not grant permission for any specific direct-contact reuse application. KEY Ingredient and direct product-contact reuse are high-consequence applications and require the strictest applicable legal, food-safety and validation controls.
Key: Final-rinse water can transfer residual chemical or microbiological contamination directly to food-contact surfaces and therefore needs end-use-specific release criteria.

Relevant controls can include microbiological quality, treatment residuals, chemical contaminants, turbidity/solids, sanitizer compatibility and time between rinse and production. DECISION INTERPRETATION Where reclaimed water is considered, validation should test the actual circuit, surface, operating temperature, downtime and residual behavior. A laboratory water sample alone cannot validate the hygienic outcome of the final rinse system. CONTROL ACTION Validate final-rinse pathways using both water and surface-release evidence. REQUIRED RECORDS Water-quality results; surface verification; sanitizer residual; line hold time; startup release record; corrective action. AUDIT / ESCALATION TRIGGER Escalate a reclaimed final-rinse system that lacks surface-level verification or automatic diversion on treatment failure. FOOD2-012 | Sources: B01, B08, B09 | Claim: claim_foodbev002_p12_core KEY Final-rinse water can transfer residual chemical or microbiological contamination directly to food-contact surfaces and therefore needs end-use-specific release criteria. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Intermediate rinses can be reuse candidates when product, allergen and chemical carryover are measured and controlled rather than assumed.

Early water may contain concentrated product or soil; later water may be relatively clean. Conductivity, turbidity, TOC/COD, pH or product-specific signals can identify quality transitions. Reusing a rinse without allergen or product-family controls can create cross-contamination. DECISION INTERPRETATION Use event-based diversion: recover product-rich fractions where appropriate, route contaminated fractions to treatment and capture the quality window that meets a defined secondary use. Do not reuse by fixed time alone when process variability is material. CONTROL ACTION Develop sensor-based or validated time/volume diversion windows for stable circuits. REQUIRED RECORDS Cycle profile; product family; allergen status; conductivity/TOC/turbidity; diversion setpoint; receiving use specification. AUDIT / ESCALATION TRIGGER Escalate rinse reuse across incompatible product/allergen families without validated controls. FOOD2-013 | Sources: B01, B02 | Claim: claim_foodbev002_p13_core KEY Intermediate rinses can be reuse candidates when product, allergen and chemical carryover are measured and controlled rather than assumed. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Closed or semi-closed cooling systems can support reuse, but higher concentration cycles can increase salts, treatment-chemical demand and microbiological control requirements.

Reclaimed sources can reduce freshwater demand, but higher dissolved solids or nutrients may increase chemical treatment, blowdown or aerosol-related concerns. Refrigeration systems also contain condensate streams with distinct quality and heat-recovery potential. DECISION INTERPRETATION Evaluate reuse using both water and energy balances. Increasing concentration cycles may reduce makeup until corrosion, scaling, treatment chemistry or blowdown quality becomes limiting. Source quality must be compatible with metallurgy and microbiological control. CONTROL ACTION Build a cooling-water mass and chemistry balance before assigning reclaimed makeup. REQUIRED RECORDS Makeup/blowdown flow; conductivity; hardness/alkalinity; chlorides; nutrients; corrosion indicators; biocide residual; drift control. AUDIT / ESCALATION TRIGGER Escalate projects that report water savings without measuring additional blowdown, chemical demand or corrosion risk. FOOD2-014 | Sources: B06, B12 | Claim: claim_foodbev002_p14_core KEY Closed or semi-closed cooling systems can support reuse, but higher concentration cycles can increase salts, treatment-chemical demand and microbiological control requirements. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Condensate recovery can reduce water and thermal-energy demand, but contamination risk and any product-contact steam requirements must be controlled separately.

However, process leaks, additives, carryover or product-contact requirements can change suitability. Steam used directly on food or food-contact surfaces may have additional quality requirements compared with closed utility steam. DECISION INTERPRETATION Segregate clean and suspect condensate, monitor for contamination indicators and return only streams that meet boiler/feedwater and hygienic requirements. Count recovered heat as a separate benefit from recovered water. CONTROL ACTION Install or validate condensate-quality diversion logic and return metering. REQUIRED RECORDS Condensate flow/temperature; conductivity; contamination indicator; treatment chemical; return rate; boiler feed specification. AUDIT / ESCALATION TRIGGER Escalate condensate return where heat-exchanger or process leaks cannot be detected reliably. FOOD2-015 | Sources: B01, B06, B10 | Claim: claim_foodbev002_p15_core KEY Condensate recovery can reduce water and thermal-energy demand, but contamination risk and any product-contact steam requirements must be controlled separately. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Membrane permeate and reject are separate products with different value and risk; neither should be labeled simply "treated water" or "waste."

Permeate quality depends on membrane integrity, feed water, pretreatment and operating conditions, while reject concentrates salts and other retained constituents. Recovery percentage alone can hide rising concentrate burden or fouling energy. DECISION INTERPRETATION Assign a specification and destination to permeate and a mass balance to reject. Monitor parameters that can indicate membrane integrity and use periodic verification for contaminants not captured by online surrogates. CONTROL ACTION Reconcile membrane feed = permeate + concentrate + cleaning/hold-up and track salt/contaminant mass. REQUIRED RECORDS Feed/permeate/reject flow; conductivity; pressure; normalized flux; integrity indicator; cleaning frequency; reject composition. AUDIT / ESCALATION TRIGGER Escalate increasing recovery when concentrate management, fouling or energy demand worsens disproportionately. FOOD2-016 | Sources: B06, B12 | Claim: claim_foodbev002_p16_core KEY Membrane permeate and reject are separate products with different value and risk; neither should be labeled simply "treated water" or "waste." Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Process condensate can look visually clean while carrying volatile organics, entrained product or chemical contaminants that depend on the process.

Dairy, beverage and other food processes may create condensates that are reusable after appropriate characterization, but contamination can arise from entrainment, volatile compounds, cleaning events or equipment leaks. DECISION INTERPRETATION Characterize condensate by operating state rather than one grab sample. Separate normal production, startup, shutdown and cleaning. Reuse should be tied to a quality window and receiving-use specification. CONTROL ACTION Create condensate diversion logic with startup/CIP exclusion unless validated otherwise. REQUIRED RECORDS Flow; conductivity; TOC/COD; turbidity; volatile markers where relevant; event state; temperature; receiving-use spec. AUDIT / ESCALATION TRIGGER Escalate reuse based only on low conductivity when organic carryover is plausible. FOOD2-017 | Sources: B01, B03, B10 | Claim: claim_foodbev002_p17_core KEY Process condensate can look visually clean while carrying volatile organics, entrained product or chemical contaminants that depend on the process. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Alternative water sources can add source-specific microbial, chemical and physical hazards together with temporal or seasonal variability.

Storage can create additional contamination or stagnation. EPA reuse resources emphasize that end-use specifications and state rules vary. DECISION INTERPRETATION External-source projects require source agreement/specification, incoming verification, treatment-barrier design, seasonal risk analysis and a backup/diversion strategy. They should normally target lower-consequence uses unless stronger legal and validation evidence supports higher-consequence uses. CONTROL ACTION Define approved alternative sources and prohibited connections. REQUIRED RECORDS Source contract/spec; seasonal data; microbial/chemical panel; storage conditions; treatment validation; state/local requirements. AUDIT / ESCALATION TRIGGER Escalate external alternative water entering the plant without independent incoming verification and clear piping separation. FOOD2-018 | Sources: B06, B07, B11 | Claim: claim_foodbev002_p18_core KEY Alternative water sources can add source-specific microbial, chemical and physical hazards together with temporal or seasonal variability. Applicability is specific to source, jurisdiction, process and evidence boundary.
Key: Flow volume and pollutant load must both be measured because a small high-strength stream can control treatment burden while a large low-load stream controls hydraulic capacity.

Mixing those streams with cooling water, condensate or later rinses dilutes concentration but not pollutant mass and can make reuse and recovery harder. Load is calculated from flow and concentration on a consistent time basis. DECISION INTERPRETATION Rank streams by both cubic meters and kilograms of key load per period. Separate high-load streams for product recovery, targeted treatment or controlled digestion where technically appropriate; protect low-load streams for reuse. CONTROL ACTION Create a flow-load matrix by source and event. REQUIRED RECORDS Flow; COD/TOC; BOD where used; TSS; nutrients; conductivity; pH; event duration; product-equivalent loss. AUDIT / ESCALATION TRIGGER Escalate projects that claim pollution reduction because concentration fell after dilution. FOOD2-019 | Sources: B01, B10 | Claim: claim_foodbev002_p19_core Concentration reduction without mass-load reduction is not source control. KEY Flow volume and pollutant load must both be measured because a small high-strength stream can control treatment burden while a large low-load stream controls hydraulic capacity.
Key: Treatment should be selected to close the measured gap between source quality and the defined end-use requirement.

Multiple barriers can improve robustness when they address different failure modes, but added complexity also increases energy, maintenance, monitoring and residuals. The required log reduction or chemical target must be justified by the risk framework and jurisdiction. DECISION INTERPRETATION Design from the end-use target backward. Identify each hazard, the barrier responsible, performance target, monitoring surrogate, validation method and failure response. Do not add unit operations that have no defined hazard-control role. CONTROL ACTION Create a treatment-barrier table linked to the hazard analysis. REQUIRED RECORDS Hazard; barrier; design target; validated performance; critical operating parameter; monitoring alarm; diversion action. AUDIT / ESCALATION TRIGGER Escalate any critical hazard with no validated barrier or any barrier with no measurable operating control. FOOD2-020 | Sources: B01, B02, B04, B05 | Claim: claim_foodbev002_p20_core KEY Treatment should be selected to close the measured gap between source quality and the defined end-use requirement.

Solids removal can reduce turbidity, membrane fouling and disinfectant demand, but it does not necessarily remove dissolved organics, salts or pathogens. DECISION INTERPRETATION Select filtration from measured particle/solids characteristics and downstream requirements. Track captured-solids mass and destination; otherwise water-quality improvement can hide a residuals problem. CONTROL ACTION Measure influent/effluent TSS or turbidity and solids capture mass. REQUIRED RECORDS Particle/TSS profile; differential pressure; filtrate quality; backwash; captured-solids mass; disposal/recovery route. AUDIT / ESCALATION TRIGGER Escalate filtration credited with dissolved-contaminant removal that has not been demonstrated.

No membrane is a universal barrier for every chemical. Integrity and normalized performance need monitoring, and concentrate must be managed. DECISION INTERPRETATION Use membrane selection to target defined contaminants and end-use quality. Validate removal for critical hazards and avoid assuming conductivity removal proves removal of all organics or microorganisms. CONTROL ACTION Set normalized flux, pressure, conductivity and integrity alarms with independent verification.
