Do you know the condition of your filter media?

Filtration is an important step in drinking water treatment, especially where the source water is not from a fully protected catchment and has a pathogen risk. It is the process of passing water through material (e.g. sand or other granular substance) to remove particulate and other impurities from the water being treated. These impurities consist of suspended particles (fine silts and clays), biological matter (bacteria, plankton, spores, cysts or other matter) and floc. Filtration processes can generally be classified as being either slow or rapid. Figure showing a simple slow sand filter concept. [Reproduced from: Bruni, M. (no date). Slow Sand Filtration.

Importance of Staff Retention in Water Treatment

The operation of water treatment plants is an essential service provided by councils and water authorities throughout Australia. Many lay people do not consider the human element of treating water, including the skills and experience required to consistently produce safe drinking water. Operators play a central role in ensuring safe drinking water supply, and in smaller regional and remote communities often retain complete responsibility for operation and maintenance of the entire supply system.

And as whole, while the attention to vital WH&S policies and procedures continues to make leaps and bounds with every decade that passes, it is the day to day, month to month and year to year heedfulness within each individual business that keeps staff safe and reminds us to never become complace

Drinking Groundwater - is it the 'safe' source we think it is?

Groundwater is an important and vital source of drinking water in Australia. Geosciences Australia (link) report that Australia's use of groundwater has increased significantly over recent decades. For example, in the 13 years from 1983 to 1996, our national reliance on groundwater increased by nearly 90 per cent. Future use of groundwater in Australia is projected to rise, especially as surface water resources may become less available due to climate change and prolonged droughts. Groundwater is also an important water source in Australia for a wide range of other purposes, such as irrigation, agriculture and industrial use. In fact, irrigation practices account for just over half of all gr
