METRO REGION WORKING GROUP
The Metro Region Working Group is made up of the IWN Champions from:
City West Water
South East Water
Yarra Valley Water.
The Metro team are participating in broader trials like Utilising satellite leak detection and Digital Metering Risk Assessment. They are also considering a number of initiatives for trial including:
ROVs for tank cleaning
Remotely operated vehicles (ROVs) have the potential to provide more efficient and effective cleaning and inspection of potable water tanks while still online.
Robot cleaning is a possible solution to cleaning tanks that cannot be taken offline for cleaning and/or do not have sufficient access for divers. For tanks where diver cleaning is possible, the use of ROVs could provide a safer alternative. The Metro group undertook the trial of ROV for tank cleaning and the report will be available soon.
If you are interested in this trial, please contact Tanya Pearson.
IWN’s Collaboration and Knowledge Sharing Program is organising a conference for passionate and enterprising water corporation employees. Only a small percentage of water industry individuals such as leaders and experts are given the opportunity to attend conferences, so this event is targeted at the dedicated rank and file of the industry so that they too can connect with their peers and learn from industry professionals.
Three employees from each Victorian Water Corporation will have the opportunity to attend the conference, in addition to the IWN Champions and presenters. The conference is free to attend and is sponsored by IWN.
The Problem: Biosolids management is a critical problem for the wastewater industry. Its environmental sustainability and socio-economic effectiveness is challenged by growing pressure on land, rising public scrutiny, intensifying regulation, and a diminishing number of biosolids disposal options. At present, no satisfactory solution exists. Currently biosolids are primarily managed by stockpiling (typically for 3 years) and subsequent application to land to allow for nutrient recovery. But this approach is labour intensive, occupies a large land area, and risks polluting land and water tables with heavy metals and nutrients. Urban sprawl is increasing both the pressure on land use and the amount of biosolids produced. Water corporations are urgently seeking alternatives. Numerous technologies have been proposed (e.g. incineration, thermal treatment, and pyrolysis), but they are limited by high capital costs, high energy and spatial footprints, and major pollution risks.
The proposal: This project will develop a disruptive PYROCO technology for converting otherwise - polluting biosolids into value-added smart carbon materials of far-reaching social, environmental and economic benefits.
Managed by an experienced team of engineers, scientists, social scientists and economists, this project will demonstrate a 75 kg/hr PYROCO design and reduce barriers to its use. The goal is to validate the social and commercial viability of the design by showcasing how it provides a low emission and low cost solution by offering 80-85% reduction in energy and 30-40% reduction in capital and operating costs compared to existing technologies. Working closely with industry, this project will reduce biosolids management costs by 30-35%.
