Australia is in the middle of an important review process for swimming pool water quality standards. On paper, this should be a welcome opportunity: reassess old assumptions, consider new science, invite independent expertise, and ensure the next generation of pool water management is safer, cheaper, and more effective.
But a more uncomfortable question now arises:
Is the system genuinely open to innovation—or merely managing a controlled update that protects entrenched interests?
Recent correspondence relating to the revision of AS 3633 – Residential and Public Pools: Water Quality raises legitimate concerns about transparency, scientific independence, and whether alternative technologies receive fair consideration.
The Problem With “Voluntary” Standards That Behave Like Mandatory Rules
Standards Australia itself explains that standards are generally voluntary documents unless adopted by legislation, regulation or contract. Their own guidance can be viewed here: https://www.standards.org.au/standards-development/what-is-standard#what-is-a-standard-id
That point is important because many people assume Australian Standards automatically carry legal force. In many cases, they do not. On their own, they often carry limited direct legal weight unless another body chooses to mandate them.
Yet in practice, many standards still operate as de facto rules.
They are routinely relied upon by:
• architects
• engineers
• consultants
• councils
• procurement officers
• insurers
• commercial operators
That means a document described as “voluntary” can still determine whether a technology is accepted, rejected, specified, insured or financed.
This practical disconnect was expressly raised in the correspondence, noting that AS3633 is often used in the field as a gatekeeping mechanism against alternative systems. If a standard carries that level of market power, then the drafting process should meet a far higher bar of independence and scientific rigour.
Who Is Actually Writing the Rules?
One of the most significant issues raised is the apparent lack of visibility around committee composition and scientific qualifications.
Questions were formally asked regarding:
• which organisations are represented
• the technical backgrounds of members
• microbiology expertise
• sanitation science capability
• toxicology knowledge
• occupational hygiene input
• public health competence
Those are not hostile questions.
They are basic governance questions.
When a standard directly influences pathogen control, swimmer safety, chemical exposure, air quality and worker health, it is entirely reasonable to ask whether suitably qualified scientists are central to the process—or peripheral to it.
Industry Representation Is Not the Same as Scientific Expertise
Many regulatory and standards systems make the same mistake: assuming industry familiarity equals scientific competence.
They are not the same thing.
Commercial stakeholders may understand products, installation trends, service models and market behaviour. That has value.
But it does not replace expertise in:
• microbial risk
• disinfection kinetics
• airborne contaminant exposure
• toxic by-product formation
• occupational hygiene
• epidemiology
• corrosion chemistry
• comparative treatment efficacy
A committee heavy with commercial interests but light on independent science risks reproducing yesterday’s assumptions under today’s branding.
The Legacy Chemistry Advantage
Another issue raised concerns whether legacy pool sanitising chemistries continue to enjoy preferential treatment simply because they are historically embedded.
Once a method becomes “standard practice,” it often receives structural advantages:
• automatic familiarity
• installer confidence
• procurement acceptance
• training ecosystem support
• regulatory inertia
• lower scrutiny than newcomers
Meanwhile, alternatives are often required to clear a much higher hurdle: prove everything, fund everything, and disprove decades of habit.
This is how incumbency protects itself.
New Safe Work Pressures Change Everything
The review of pool standards is not happening in a vacuum.
Australia is simultaneously moving toward tighter workplace expectations around airborne contaminants, including chlorine exposure. That has direct implications for:
• indoor aquatic centres
• plant rooms
• pool halls
• maintenance staff
• lifeguards
• coaches
• contractors
The correspondence warned that a revised standard which ignores evolving workplace health settings could be outdated upon release. A modern pool standard cannot focus only on water chemistry while ignoring air chemistry.
Proven Alternatives Already Exist
This debate is often framed as if alternatives are speculative.
They are not.
Systems such as Enviroswim have operated for decades in residential and commercial environments, including public pools, with independent testing, certification pathways and long-term field data cited by proponents.
Whether one agrees with every claim is beside the point.
The real issue is this:
Are such systems being evaluated fairly under evidence-based criteria—or excluded because they do not fit the old chlorine-first model?
What Collusion Often Looks Like in Real Life
Collusion does not always require secret meetings or explicit conspiracy.
Sometimes it is softer and more common:
• the same insiders rotating through committees
• trade bodies influencing standards language
• training organisations certifying industry views
• procurement relying on outdated norms
• regulators deferring to industry consensus
• innovators being told to wait for consultation
That kind of ecosystem can preserve the status quo without anyone believing they are doing anything improper.
Yet the result is the same.
What a Credible Review Should Include
If public confidence matters, the AS3633 process should visibly demonstrate:
- Independent microbiologists and water scientists at the core of drafting
- Transparent disclosure of committee representation
- Clear conflict-of-interest management
- Equal evidentiary treatment of old and new systems
- Consideration of airborne exposure and by-products
- Publicly visible submissions and responses
- Performance-based outcomes rather than chemistry preference
Anything less invites doubt.
The Bigger Question for Australia
Do we want pool water regulation built around:
• habit
• commercial convenience
• chemical legacy systems
• insider networks
Or do we want it built around:
• modern science
• measurable outcomes
• worker safety
• swimmer wellbeing
• lower operating costs
• genuine innovation
That is the real issue now before the industry.
Because once standards become gatekeepers instead of guides, the public stops being protected—and the status quo starts being protected instead.
