Chemical Tips Understanding ORP Oxidation Reduction Potential (ORP) measures the true efficacy of the oxidisers present in the water in millivolts. An ORP reading of 700mV to 720mV is considered adequate for fast and effective disinfection in pools and most Australian health departments recommend it for commercial pools. ORP will rise and fall according to the level of cyanuric acid, pH and contaminants in the water. For example, a pool showing a Free Chlorine level of 2ppm may show an ORP reading of 720 at a pH level of 7.4. As the pH level changes so too will the ORP. At a pH of 7.8 the ORP may read below 700 or at a pH of 7 may read above 750. Similarly a stabiliser reading of 20 will show a much higher ORP level than the same pool with a stabiliser level of 50+. As swimmers introduce contaminants such as sweat, body fats or urine into the pool water, the ORP will reduce. As the ORP level changes it enables the sanitiser controller to react to the increased chlorine demand and commence feeding as required. Chlorine controllers will only monitor and control the Free Chlorine set point but do not allow for changes in pH, contaminants etc. (See Issue 118 for more on pH.) These tips are supplied by pool industry pioneer and chemistry expert David Lloyd. For more information call International Quadratics on (02) 9774 5550.

SPASA responds to NSW Fair Trading reforms Following the release of NSW Fair Trading’s consultation paper, SPASA Australia has responded to elements pertinent to the swimming pool and spa industry. The four most pertinent items are that SPASA: • Rejects the removal of licensing for Fencing, Glazing and Paving; • Advocates removing Owner-Builder licensing; • Supports more focus and the expansion of mandatory CPD program; • Recommends the Security of Payment Act be expanded to include homeowners. In the introduction to the document SPASA says: “The swimming pool and spa industry in NSW is directly affected by the operation of occupational and business licensing requirements. “SPASA’s position is to support the operation of an appropriate licensing framework for the swimming pool and spa and broader industries. The ultimate key is for the framework to be set at a reasonable level to

achieve the intended consumer and safety outcomes and avoid risks associated with ‘unqualified’ persons or organisations undertaking work. “Licensing should minimise risks by ensuring that people who perform work which is critical to safety have as a minimum achieved a certain standard of technical skills. When any building or associated work is done badly then it has the potential to cause significant harm to people and/or costs to property. “In considering the effects of red tape on licensing there is, in SPASA’s view, a need to rethink the concept that by removing licensing that it will result in the positive removal of red tape. “Whilst this may be the case in some instances, it can never be acceptable in situations where licensing relates to work which is critical to improving safety outcomes in and around swimming pools and spa environments.” The SPASA Submission on the Easy and Transparent Trading Consultation Paper is available at


New certification program to boost industry sustainability A new, comprehensive efficiency and sustainability certification system was launched at SPLASH! during the national awards gala. SPASA Australia’s Climate Care Certification Program enables members to promote their products, services and installations under an industry approved, environmentally sustainable program. A Climate Care Certified product, system or installation/retrofit/construction is one that creates a new benchmark for swimming pools and spas which utilise: • Water efficiency/sustainability • Energy efficiency • Noise reduction measures • Environmentally sustainable designs • Efficiency/sustainability innovations Smart Approved WaterMark is the certification partner for water efficient products for Climate Care Certified. Certification with Smart Approved WaterMark provides a Climate Care applicant with verification of water saving claims required in the application.

Climate Care Certified benefits

Having your products, systems or installations/ retrofits/constructions Climate Care Certified enhances your ability to:

• Highlight your product/system/installation’s environmentally sustainable qualities; • Show your commitment to preserving the environment and to industry best practice; • Gain a competitive edge in the market place by joining a network of environmentally conscious providers, listed as Climate Care Certified on the searchable database; • Increase sales and productivity by having your industry innovations: recognised, endorsed, validated and approved as Climate Care Certified; • I mprove your reputation and credibility with consumers, colleagues and industry partners, and; •D  emonstrate your investment in the industry’s sustainable future and inspire others to do the same. As part of the registration process, all products, systems and installations submitted for registration will undergo a claims verification process undertaken by a SPASA appointed panel prior to being provided with the Climate Care Certification. As a launch offer, SPASA members who apply to Smart Approved WaterMark are able to get both Climate Care Certification and Smart Approved WaterMark for the cost of one (valid for two years).
