Ultra Clear domestic systems have been designed and tested to meet the NSW Health Department Guidelines and AS 1546.3:2017 with advanced secondary effluent. Both systems were tested at the Jimboomba, QLD test site with the testing program monitored by Global Certification Pty Ltd.
The average daily loading of raw sewage influent during testing for Model ST8 was 1,200 litres with a 5 day stress test loading of 1,600 litres per day. The average daily loading of raw sewage influent during testing for Model ST10 was 1,500 litres with a 5 day stress test loading of 2,000 litres per day.
Both Ultra Clear systems consistently achieved far in excess of the required results during testing. Ultra Clear has been proven to remove over 98% of suspended solids, with removal of harmful micro organisms.
Ultra Clear systems have been designed by Darryl Rebbeck, a consultant in the manufacturing industry, who has had over 29 years experience in the wastewater industry and has a full knowledge of the operation of most types of aerated systems. The systems have been designed for efficient maintenance and servicing by providing easy and full access to all chambers for complete maintenance. This enables the system to function at optimum efficiency at all times.
The single tank systems have inlets of 550mm for ST10 and 750mm for ST8, which allow for a greater fall to the tank from the house, for easier installation and also decreasing the need for risers.
Ultra Clear systems are manufactured using concrete tanks and baffles manufactured by Highland Tanks Pty Ltd trading as Highland Concrete Tanks, at 16 Gantry Place, Braemar, to comply with Australian Standards to AS/NZS 1546.1:2008. NSW Health Certificate of Accreditation No. CofA STCW005 and Global Certification Pty Ltd Product Certificate of Registration No. 631.
The Test Results
Testing of Ultra Clear Models ST8 and ST10 was conducted at the Jimboomba QLD test site in accordance with AS 1546.3:2017. The testing program was monitored by Global Certification Pty Ltd.

- Biochemical Oxygen Demand (BOD 5) measures the amount of organic matter in effluent. The lower the test result the cleaner the water.
- E coli measures the amount of harmful pathogens in the water. The lower the reading, the clearer and cleaner the treated effluent.
- Suspended Solids (TSS) measure solid particles in the water.
- Turbidity the lower the turbidity, the clearer the clarity of the treated effluent
