STANDARDS AUSTRALIA • AS 3633
Why Enviroswim Has Published These Submissions
For more than 25 years, Enviroswim has researched, developed and manufactured Australian water-treatment technology supported by independent laboratory efficacy testing, public-pool field experience, international certification and scientific review. Throughout that time, we have consistently supported one simple principle: every swimming-pool sanitation system should be judged by the same independently verifiable evidence.
Standards Australia Limited is an independent, non-government, not-for-profit company. It is not a government regulator, public-health authority or elected lawmaking body. Australian Standards are generally voluntary unless they are adopted into legislation, regulation or contracts. In practice, however, a published standard can acquire quasi-regulatory force through government guidance, council approvals, tenders, consultant specifications, insurance requirements, training materials and contractual conditions.
That makes the development of DR AS 3633:2026 a matter of considerable public interest.
The draft does not expressly prohibit alternative sanitation technologies. Nevertheless, it defines minimum efficacy by reference to chlorine, treats a conventional chlorine-based system as the principal comparator and places a separate, visible proof burden on alternative systems. If published in its present form, this structure could establish chlorine as Australia’s de facto compliance benchmark without requiring every incumbent sanitation pathway to satisfy the same transparent, product-specific and operating-condition-specific evidence test.
There is also a serious governance concern. The individual members of the responsible technical committee, their relevant scientific qualifications, their declared commercial interests and the measures used to manage conflicts are not fully visible to the public. Decisions capable of influencing national public-health practice, competition and market access should not be made by largely unidentified participants without a clear and auditable evidence trail.
This lack of transparency creates a genuine risk that established commercial interests and conventional chemical practices will be protected by the standard’s structure—whether deliberately or simply through institutional familiarity—while independently validated Australian innovation is required to clear a higher evidentiary barrier.
Enviroswim is not asking Standards Australia to endorse our technology, weaken public-health safeguards or prohibit chlorine. We are asking for the opposite: one rigorous, technology-neutral evidentiary standard applying equally to chlorine, bromine, stabilised chlorine, hydrogen peroxide, PHMB, ozone, ultraviolet treatment, advanced oxidation and complete multi-barrier systems such as Enviroswim.
We have therefore published below the five submissions lodged through Standards Australia’s public-comment portal. They address evidence parity, cyanuric acid, pathogen control, disinfection by-products, worker safety, committee transparency, industry competency and the risk of a voluntary standard becoming quasi-regulation.
Readers are invited to examine the submissions and supporting evidence and reach their own conclusions. If the evidence supporting the draft’s preferred pathways exists, it should be disclosed and mapped to the claimed outcomes. If it does not, inherited practice, registration status and commercial familiarity must not be converted into a national scientific presumption.
Enviroswim’s submissions
SUBMISSION 01
Clause by Clause Submission
Date submitted: 19/08/26
Enviroswim’s 19 August 2026 submission calls for major technical revision of Draft AS 3633 before it is finalised. It identifies a missing microbiological criteria table, contradictory requirements that may continue to mandate chlorine or bromine even after an alternative system has been independently validated, and unequal evidentiary requirements for conventional and alternative treatment technologies.
The submission recommends one transparent, outcome-based assessment framework for all pool-water treatment systems, supported by independent laboratory testing and full-scale field evidence. It also raises concerns regarding cyanuric acid, disinfection by-products, the treatment of hydrogen peroxide and PHMB, outdated scientific references, operator competency and pool-chemical security.
Enviroswim asks Standards Australia to correct the technical defects, independently validate the proposed testing pathway and reissue the revised draft for further public comment.
SUBMISSION 02
Evidence based critique
Date submitted: 19/08/26
Enviroswim’s evidence-based critique examines whether Draft AS 3633 is technically complete, internally consistent and genuinely technology-neutral before it becomes a primary national reference for pool-water quality.
The critique identifies a missing microbiological criteria table, contradictory requirements affecting alternative systems, unequal evidentiary burdens and weaknesses in the proposed Appendix I validation method. It also examines cyanuric acid, disinfection by-products, occupational exposure, chemical security, operator competency and the draft’s treatment of hydrogen peroxide, PHMB, mineral pools and multi-barrier technologies.
Enviroswim does not seek automatic acceptance or the exclusion of chlorine. It asks that every treatment pathway be assessed against the same transparent, independently reviewable evidence requirements.
The submission recommends correcting the technical defects, publishing the evidence supporting each permitted pathway, obtaining independent multidisciplinary review and reissuing the amended draft for further public comment before finalisation
SUBMISSION 03
Supplementry Technical Submission
Date submitted: 23/08/26
Enviroswim’s supplementary technical submission expands on its original comments by examining sanitiser efficacy, cyanuric acid, microbiological outcomes and evidence parity under Draft AS 3633.
The submission argues that a familiar chemical residual is an operational control measure—not a substitute for transparent proof of efficacy. It recommends that chlorine, ionisation, multi-barrier systems, PHMB and other treatment technologies be assessed against the same organisms, log reductions, contact times, safety margins and full-scale field-validation requirements.
It also explains why cyanuric acid and real-world operating conditions can affect chlorine performance and why a routine free-chlorine reading alone does not establish equivalent disinfection outcomes.
Enviroswim presents its independent laboratory results, NSF/ANSI 50 certification history, operational evidence and reports by water microbiologist Dr Simon Toze, while asking Standards Australia to correct the draft’s technical inconsistencies and provide an issue-by-issue response before finalisation.
SUBMISSION 04
Further Public Comment
Date submitted: 31/08/26
Enviroswim’s further public comment addresses a central structural problem in Draft AS 3633: the draft does not apply the same evidentiary standard to every sanitiser pathway.
The submission argues that registration, historical use, patents, component certification and manufacturer statements do not constitute independent proof that a complete installed pool-treatment system delivers its claimed public-health outcomes. It proposes one evidence rule for chlorine, bromine, hydrogen peroxide, PHMB, ionisation, mineral-electrolyte systems, ozone, ultraviolet, advanced oxidation and integrated alternative systems.
Evidence should identify the exact system, organisms, log reductions, contact times, operating conditions, laboratory independence and representative field validation.
Supported by World Health Organization guidance, Enviroswim asks Standards Australia to insert the missing microbiological criteria, distinguish residual readings from demonstrated efficacy, independently review the framework and correct the unequal evidence pathways before ballot or publication.
SUBMISSION 05
Further Technical addendum
Date submitted: 08/09/26
Enviroswim’s cyanuric acid technical addendum addresses a specific public-health gap in Draft AS 3633: the assumption that a measured free-chlorine residual demonstrates equivalent disinfection performance when cyanuric acid is present.
Drawing on peer-reviewed research, NSW Health protocols and CDC guidance, the submission explains that cyanuric acid can materially slow chlorine’s action, particularly against chlorine-resistant organisms such as Cryptosporidium. However, the draft permits cyanuric acid concentrations from 5 to 50 mg/L without establishing a validated relationship between free chlorine, cyanuric acid, pH, temperature, contact time and organism-specific performance.
Enviroswim asks Standards Australia to introduce a cyanuric-acid-aware performance rule, revise the description of chlorine residual as “minimum efficacy,” add specific contamination-response requirements and publish the evidence supporting the permitted operating range. A free-chlorine reading alone should not be treated as proof of equivalent disinfection efficacy.
SUBMISSION 06
Overarching Supplementary submission
Date submitted: 19/09/26
Enviroswim’s overarching public-interest briefing consolidates the technical, regulatory and governance concerns raised in its earlier submissions on Draft AS 3633:2026. It explains how a voluntary Australian Standard can become a de facto compliance requirement through government guidance, tenders, contracts, insurance, training and professional practice.
Although the draft does not prohibit alternative sanitation technologies, it defines minimum efficacy by reference to chlorine, uses conventional chlorine treatment as its principal comparator and places a separate proof burden on alternatives. The briefing also examines cyanuric acid, resistant pathogens, disinfection by-products, airborne exposure, APVMA evidence gaps, workforce competency and committee transparency.
Enviroswim is not seeking to prohibit chlorine or secure automatic approval for its technology. It calls for one rigorous, technology-neutral evidence standard for every sanitation pathway, supported by transparent governance, independent review and disclosure of the evidence relied upon before the draft proceeds to ballot or publication.
