South East Water has developed a vibration sensor device named Sotto to detect leaks within its network in order to reduce wastage…
Antimicrobial resistance (AMR) – the ability of microorganisms to resist antibiotics, antifungals, and antivirals – is one of the greatest health threats of the 21st century…
Real time monitoring and process control is a crucial component of optimal, pro-active water and wastewater management but there is a lack of information about real-world experience, operation, return on investment and the costs that are related to online monitoring…
Satellite earth observation technologies have developed rapidly, with strong potential emerging for satellite remote sensing to offer new insights and opportunities to water utilities and agencies…
Recycling wastewater to a standard that makes it fit for use in irrigation is an efficient and cost-effective strategy for managing water resources, and has prompted the installation of separate pipe and tap reticulation systems in domestic housing schemes such as at Rouse Hill in Sydney…
One wastewater treatment (WWT) option is disinfection with ultra violet (UV) light to remove pathogens and some contaminants, but substances in treated wastewater, such as particles of solid matter, can absorb the UV radiation and reduce its disinfecting activity…
Microbial pathogens are removed from source waters to make safe drinking water. Health-based targets (HBTs) refer to the quantities of pathogens that will NOT cause illness, and water treatment plants (WTPs) must ensure that the numbers of pathogens in potable water are the same or lower than the HBTs…
A survey of water utilities identified the top five challenges faced in daily operations, and technical, economic and literature reviews identified remote sensing strategies and technologies to address these five operational issues…
The management of blue-green algae (cyanobacteria), and the toxins and taste and odour compounds they produce, have been the focus of more than 30 years of research, but there is still a need for a suite of user-friendly tools to assess and manage aesthetic and toxin risks…
Although water utilities recognise the value of online instruments that provide real-time monitoring capability, there are problems with visualising and interpreting datasets, and with distinguishing between data resulting from real-world changes in treatment plant operating conditions, for example changed turbidity or flow, and instrument failure…
