FEBRUARY 2014 WATER 95 Water Business to be designed in a way that would ensure it would be easily maintainable while also providing easy-to-access spares in the event that equipment would need to be replaced. "At NHP, we are committed to not only tting projects with the required products, but equally value our after sales service. We are pleased to have established a Parts Management Agreement (PMA) with the Cairns Regional Council to decrease the size of the spares required to support this vital infrastructure, and ensure we are there when required,", said Mark Smedts, Business Development -- Projects WA. The upgraded facilities have considerably expanded capacity to meet population growth predictions catering for a population of more than 200,000 people, and the high- quality recycled water will aid non-drinking re-use purposes such as industrial cooling applications, concrete production and dust suppression, irrigation on golf courses, parks and sporting grounds, and agriculture.

The real-time, accurate quanti cation of total bioburden provides operators with the ability to pinpoint the problem area within a system, apply treatment and quantify the ef cacy of this treatment within a matter of hours, compared to days or weeks with traditional methods. This rapid feedback enables the expedient and proactive adjustment of system operations to ensure that localised problems do not evolve into major problems. Water treatment operators typically use Heterotrophic Plate Counts to estimate the total population of microorganisms in a water sample and to supplement regulated parameters such as Total Coliform and E. coli tests. While it can be useful as a general indicator of water quality, the shortcomings of the HPC are well documented. Several species that can cause signi cant problems in water systems such as nitri ers, sulfate- reducing bacteria, iron bacteria and algae are not easily culturable and, therefore, would otherwise go unnoticed. Since results are not known until several days later, HPC tests provide minimal value as a control tool, since changes in the water system have already occurred well after they have been detected. Culture test results may vary according to the media used, highlighting its reliance on detection of cultivable organisms (which typically represent a small proportion of total microorganisms). As well, some species such as algae are dif cult to remove once they are established, so it is important to detect changes in water quality as early as possible. In general, since the main goal of an HPC test is to reveal changes in the overall water quality, the value would undoubtedly be much higher if the results were known at the time the sample was collected instead of several days afterward.
