Abstract:
New housing developments are now commonly incorporating dual reticulation water systems for the redistribution of recycled water back to households for non-potable use. Within such distribution systems is the potential for cross-connections between recycled and drinking water pipelines, and a number of such events have been documented both in Australia and internationally. While many cross-connections are unlikely to present a source of health concern given the high level of recycled water treatment, they do have the potential to negatively impact public confidence in dual reticulation systems. A rapid and highly sensitive method of cross-connection detection is required to increase consumer confidence in the construction and maintenance of such recycled water distribution systems. This paper reviews a number of current and potential cross-connection detection methods, highlighting the use of fluorescence spectroscopy as a highly promising analytical tool for portable cross-connection detection.
